Services provided by the cloud infrastructure system can dynamically scale to meet the needs of its users. A specific instantiation of a service provided by cloud infrastructure system is referred to herein as a service instance. In general, any service made available to a user via a communication network such as the Internet from a cloud service provider's system is referred to as a cloud service. Typically, in a public cloud environment, servers and systems that make up the cloud service provider's system are different from the customer's own on-premises servers and systems. For example, a cloud service provider's system may host an application and a user may, via a communication network such as the Internet, on demand, order and use the application.
[0038] A service in a computer network cloud infrastructure includes protected computer network access to storage, a hosted database, a hosted web server, a software application, or other service provided by a cloud vendor to a user, or as otherwise known in the art. For example, a service can include password-protected access to remote storage on the cloud through the Internet. As another example, a service can include a web service-based hosted relational database and script-language middleware engine for private use by a networked developer. As another example, a service can include access to an email software application hosted on a cloud vendor's web site.

The computing devices that make up cloud infrastructure system 100 may run any of operating systems or a variety of additional server applications and/or mid-tier applications, including HTTP servers, FTP servers, CGI servers, Java servers, database servers, and the like. Exemplary database servers include without limitation those commercially available from Oracle, Microsoft, Sybase, IBM and the like.
[0060] In various embodiments, cloud infrastructure system 100 may be adapted to automatically provision, manage and track a customer's subscription to services offered by cloud infrastructure system 100. In one embodiment, as depicted in FIG. 2, the components in cloud infrastructure system 100 include an Identity Management (IDM) module 200, a services module 202, a Tenant Automation System (TAS) module 204, a Service Deployment Infrastructure (SDI) module 206, an Enterprise Manager (EM) module 208, one or more front-end web interfaces such as a store user interface (UI) 210, a cloud user interface (UI) 212, and a support user interface (UI) 216, an order management module 214, sales personnel 218, operator personnel 220 and an order database 224. These modules may include or be provided using one or more computers and/or servers which may be general purpose computers, specialized server computers, server farms, server clusters, or any other appropriate arrangement and/or combination.
[0061] In one embodiment, one or more of these modules can be provided by cloud management functionality 108 or IaaS platform 110 in cloud infrastructure system 100. The various modules of the cloud infrastructure system 100 depicted in FIG. 2 are meant for illustrative purposes only and are not intended to limit the scope of embodiments of the present invention. Alternative embodiments may include more or fewer modules than those shown in FIG. 2.
[0062] In an exemplary operation, at (1) a customer using a client device such as client device 224 or 226 may interact with cloud infrastructure system 100 by browsing the various services provided by cloud infrastructure system 100 and placing an order for a subscription for one or more services offered by cloud infrastructure system 100. In certain embodiments, the customer may access store UI 210 or cloud UI 212 and place a subscription order via these user interfaces.
[0063] The order information received by cloud infrastructure system 100 in response to the customer placing an order may include information identifying the customer and one or more services offered by the cloud infrastructure system 100 that the customer intends to subscribe to. A single order may include orders for multiple services. For instance, a customer may login to cloud UI 212 and request a subscription for a CRM service and a Java cloud service in the same order.
[0064] Additionally, the order may also include one or more service levels for the ordered services. As used herein, and as will be discussed in greater detail below, a service level for a service determines the amount of resources to be allocated for providing the requested service in the context of the subscription, such as the amount of storage, amount of computing resources, data transfer facilities, and the like. For example, a basic service level may provide a minimum level of storage, data transmission, or number of users, and higher service levels may include additional resources.
[0065] In addition, in some instances, the order information received by cloud infrastructure system 100 may include information indicative of a customer level, and the time period during which the service is desired. The customer level specifies the priority of the customer making the subscription request. In one example, the priority may be determined based on the quality of service that the cloud infrastructure system 100 guarantees or promises the customer as specified by a Service Level Agreement (SLA) agreed to between the customer and the provider of the cloud services. In one example, the different customer levels include a basic level, a silver level and a gold level. The time period for a service may specify the start date and time for the service and the time period for which the service is desired (e.g., a service end date and time may be specified).
[0066] In one embodiment, a customer may request a new subscription via store UI 210 or request for a trial subscription via cloud UI 212. In certain embodiments, store UI 210 may represent the service provider's eCommerce store front (e.g., www.oracle.com/store for Oracle Cloud services). Cloud UI 212 may represent a business interface for the service provider. Consumer can explore available services and sign up for interested services through cloud UI 212. Cloud UI 212 captures user input necessary for ordering trial subscriptions provided by cloud infrastructure system 100. Cloud UI 212 may also be used to view account features and configure the runtime environment located within cloud infrastructure system 100. In addition to placing an order for a new subscription, store UI 210 may also enable the customer to perform other subscription-related tasks such as changing the service level of a subscription, extending the term of the subscription, increasing the service level of a subscription, terminating an existing subscription, and the like.
[0067] After an order has been placed per (1), at (2), the order information that is received via either store UI 210 or cloud UI 212 is stored in order database 224, which can be one of several databases operated by cloud infrastructure system 100 and utilized in conjunction with other system elements. While order database 224 is shown logically as a single database in FIG. 2, in actual implementation, this may comprise one or more databases.
[0068] At (3), the order is forwarded to order management module 214. Order management module 214 is configured to perform billing and accounting functions related to the order such as verifying the order and upon verification, booking the order. In certain embodiments, order management module 214 may include a contract management module and an install base module. The contract management module may store contract information associated with the customer's subscription order such as the customer's service level agreement (SLA) with cloud infrastructure system 100. The install base module may include detailed descriptions of the services in the customer's subscription order. In addition to order information, the install base module may track installation details related to the services, product status and support service history related to the services. As a customer orders new services or upgrades existing ones, the install base module may automatically add new order information.
[0069] At (4), information regarding the order is communicated to TAS module 204. In one embodiment, TAS module 204 utilizes the order information to orchestrate the provisioning of services and resources for the order placed by the customer. At (5), TAS component 204 orchestrates the provisioning of resources to support the subscribed services using the services of SDI module 206. At (6) TAS module 204 provides information related to the provisioned order received from SDI module 206 to services module 202. In some embodiments, at (7), SDI module 206 may also use services provided by services module 202 to allocate and configure the resources needed to fulfill the customer's subscription order.
[0070] At (8), services module 202 sends a notification to the customers on client devices 224, 226 and 228 regarding the status of the order.
[0071] In certain embodiments, TAS module 204 functions as an orchestration component that manages business processes associated with each order and applies business logic to determine whether an order should proceed to provisioning. In one embodiment, upon receiving an order for a new subscription, TAS module 204 sends a request to SDI module 206 to allocate resources and configure those resources needed to fulfill the subscription order. SDI module 206 enables the allocation of resources for the services ordered by the customer. SDI module 206 provides a level of abstraction between the cloud services provided by cloud infrastructure system 100 and the physical implementation layer that is used to provision the resources for providing the requested services. TAS module 204 may thus be isolated from implementation details such as whether or not services and resources are actually provisioned on the fly or pre-provisioned and only allocated/assigned upon request.
[0072] In certain embodiments, a user may use store UI 210 to directly interact with order management module 214 to perform billing and accounting related functions such as verifying the order and upon verification, booking the order. In some embodiments, instead of a customer placing an order, at (9), the order may instead be placed by sales personnel 218 on behalf of the customer such as a customer's service representative or sales representative. Sales personnel 218 may directly interact with order management module 214 via a user interface (not shown in FIG. 2) provided by order management module 214 for placing orders or for providing quotes for the customer. This, for example, may be done for large customers where the order may be placed by the customer's sales representative through order management module 214. The sales representative may set up the subscription on behalf of the customer.
[0073] EM module 208 is configured to monitor activities related to managing and tracking a customer's subscription in cloud infrastructure system 100. EM module 208 collects usage statistics for the services in the subscription order such as the amount of storage used, the amount data transferred, the number of users, and the amount of system up time and system down time. At (10), a host operator personnel 220, who may be an employee of a provider of cloud infrastructure system 100, may interact with EM module 208 via an enterprise manager user interface (not shown in FIG. 2) to manage systems and resources on which services are provisioned within cloud infrastructure system 100.
[0074] Identity management (IDM) module 200 is configured to provide identity services such as access management and authorization services in cloud infrastructure system 100. In one embodiment, IDM module 200 controls information about customers who wish to utilize the services provided by cloud infrastructure system 100. Such information can include information that authenticates the identities of such customers and information that describes which actions those customers are authorized to perform relative to various system resources (e.g., files, directories, applications, communication ports, memory segments, etc.) IDM module 200 can also include the management of descriptive information about each customer and about how and by whom that descriptive information can be accessed and modified.
[0075] In one embodiment, information managed by the identity management module 200 can be partitioned to create separate identity domains. Information belonging to a particular identity domain can be isolated from all other identity domains. Also, an identity domain can be shared by multiple separate tenants. Each such tenant can be a customer subscribing to services in the cloud infrastructure system 100. In some embodiments, a customer can have one or many identity domains, and each identity domain may be associated with one or more subscriptions, each subscription having one or many services. For example, a single customer can represent a large entity and identity domains may be created for divisions/departments within this large entity. EM module 208 and IDM module 200 may in turn interact with order management module 214 at (11) and (12) respectively to manage and track the customer's subscriptions in cloud infrastructure system 100.
[0076] In one embodiment, at (13), support services may also be provided to the customer via a support UI 216. In one embodiment, support UI 216 enables support personnel to interact with order management module 214 via a support backend system to perform support services at (14). Support personnel in the cloud infrastructure system 100 as well as customers can submit bug reports and check the status of these reports via support UI 216.
[0077] Other interfaces, not shown in FIG. 2 may also be provided by cloud infrastructure system 100. For example, an identity domain administrator may use a user interface to IDM module 200 to configure domain and user identities. In addition, customers may log into a separate interface for each service they wish to utilize. In certain embodiments, a customer who wishes to subscribe to one or more services offered by cloud infrastructure system 100 may also be assigned various roles and responsibilities. In one embodiment, the different roles and responsibilities that may be assigned for a customer may include that of a buyer, an account administrator, a service administrator, an identity domain administrator or a user who utilizes the services and resources offered by cloud infrastructure system 100. The different roles and responsibilities are described more fully in FIG. 4 below.
[0078] FIG. 3A depicts a simplified flowchart 300 depicting processing that may be performed by the TAS module in the cloud infrastructure system, in accordance with an embodiment of the present invention. The processing depicted in FIG. 3A may be implemented in software (e.g., code, instructions, program) executed by one or more processors, hardware, or combinations thereof. The software may be stored in memory (e.g., on a memory device, on a non-transitory computer-readable storage medium). The particular series of processing steps depicted in FIG. 3A is not intended to be limiting. Other sequences of steps may also be performed according to alternative embodiments. For example, alternative embodiments of the present invention may perform the steps outlined above in a different order. Moreover, the individual steps illustrated in FIG. 3A may include multiple sub-steps that may be performed in various sequences as appropriate to the individual step. Furthermore, additional steps may be added or removed depending on the particular applications. One of ordinary skill in the art would recognize many variations, modifications, and alternatives. In one embodiment, the processing depicted in FIG. 3A may be performed by one or more components in TAS component 204 as will be described in detail in FIG. 3B.
[0079] At 302, a customer's subscription order is processed. The processing may include validating the order, in one example. Validating the order includes ensuring that the customer has paid for the subscription and ensuring that the customer does not already have subscriptions with the same name or that the customer is not attempting to create multiple subscriptions of the same type in the same identity domain for subscription types for which this is disallowed (such as, in the case of a CRM service). Processing may also include tracking the status of an order for each order that is being processed by cloud infrastructure system 100.
[0080] At 304, a business process associated with the order is identified. In some instances, multiple business processes may be identified for an order. Each business process identifies a series of steps for processing various aspects of the order. As an example, a first business process may identify one or more steps related to provisioning physical resources for the order, a second business process may identify one or more steps related to creating an identity domain along with customer identities for the order, a third business process may identify one or more steps for related to performing back office functions such as creating a customer record for the user, performing accounting functions related to the order, and the like. In certain embodiments, different business processes may also be identified for processing different services in an order. For example, different business process may be identified to process a CRM service and a database service.
[0081] At 306, the business process identified for the order in 304 is executed. Executing the business process associated with the order may include orchestrating the series of steps associated with the business process identified in step 304. For example, executing a business process related to provisioning physical resources for the order may include sending a request to SDI module 206 to allocate resources and configure those resources needed to fulfill the subscription order.
[0082] At 308, a notification is sent to the customer regarding the status of the provisioned order. Additional description related to performing steps 302, 304, 306 and 308 is provided in detail in FIG. 3B.
[0083] FIG. 3B depicts a simplified high level diagram of one or more sub-modules in the TAS module in the cloud infrastructure system, in accordance with an embodiment of the present invention. In one embodiment, the modules depicted in FIG. 3B perform the processing described in steps 302-308 discussed in FIG. 3A. In the illustrated embodiment, TAS module 204 comprises an order processing module 310, a business process identifier 312, a busines process executor 316, an overage framework 322, a workflow identification module 324, and a bundled subscription generator module 326. These modules may be implemented in hardware, or software, or combinations thereof. The various modules of the TAS module depicted in FIG. 3B are meant for illustrative purposes only and are not intended to limit the scope of embodiments of the present invention. Alternative embodiments may include more or fewer modules than those shown in FIG. 3B.
[0084] In one embodiment, order processing module 310 receives an order from a customer from one or more input sources 321. For example, order processing module 310 may directly receive an order via cloud UI 212 or store UI 210, in one embodiment. Alternatively, order processing module 310 may receive an order from order management module 214 or order database 224. Order processing module 310 then processes the order. In certain embodiments, processing the order includes generating a customer record which includes information about the order such as a service type, a service level, a customer level, the type of resources, the amount of the resources to be allocated to the service instance and a time period during which the service is desired. As part of the processing, order processing module 310 also determines whether the order is a valid order. This includes ensuring that the customer does not already have subscriptions with the same name or that the customer is not attempting to create multiple subscriptions of the same type in the same identity domain for subscription types where this is disallowed (such as, in the case of a fusion CRM service).
[0085] Order processing module 310 may also perform additional processing on the order. Processing may include tracking the status of an order for each order that is being processed by cloud infrastructure system 100. In one embodiment, order processing module 310 may process each order to identify a number of states pertaining to the order. In one example, the different states of an order may be an initialized state, a provisioned state, an active state, an administration required state, an error state, and the like. An initialized state refers to the state of a new order; a provisioned state refers to the state of an order once the services and resources for the order have been provisioned. An order is in an active state when the order has been processed by TAS module 204 and a notification to that effect has been delivered to the customer. An order is in an administration required state when intervention by an administrator is needed to resolve the issue. The order is in an error state when the order cannot be processed. In addition to maintaining the order progress status, order processing module 310 also maintains detailed information about any failures encountered during process execution. In other embodiments, and as will be discussed in detail below, the additional processing performed by order processing module 310 may also include changing the service level for a service in the subscription, changing the services included in the subscription, extending the time period of the subscription, and canceling the subscription or specifying different service levels for different time periods in the subscription.
[0086] After an order has been processed by order processing module 310, business logic is applied to determine whether the order should proceed to provisioning. In one embodiment, as part of orchestrating the order, business process identifier 312 receives the processed order from order processing module 310 and applies business logic to identify a particular business process to use for the order being processed. In one embodiment, business process identifier 312 may utilize information stored in a service catalog 314 to determine the particular business process to be used for the order. In one embodiment, and as discussed in FIG. 3A, multiple business processes may be identified for an order and each business process identifies a series of steps for processing various aspects of the order. In another embodiment, and as discussed above, different business processes may be defined for different types of services, or combinations of services such as a CRM service or a database service. In one embodiment, service catalog 314 may store information mapping an order to a particular type of business process. Business process identifier 312 may use this information to identify a specific business process for the order being processed.
[0087] Once a business process has been identified, business process identifier 312 communicates the particular business process to be executed to business process executor 316. Business process executor 316 then executes steps of the identified business process by operating in conjunction with one or more modules in the cloud infrastructure system 100. In some embodiments, business process executor 316 acts as an orchestrator for performing the steps associated with a business process. For example, the business process executor may interact with order processing module 310 to execute steps in a business process that identifies workflows related to the order, determines the overage of services in the order or identifies service components related to the order.
[0088] In one example, business process executor 316 interacts with SDI module 206 to execute steps in a business process for allocating and provisioning resources for services requested in the subscription order. In this example, for each step in the business process, business process executor 316 may send a request to SDI component 206 to allocate resources and configure resources needed to fulfill the particular step. SDI component 206 is responsible for the actual allocation of the resources. Once all the steps of the business processes of an order have been executed, business process executor 316 may send a notification to the customer of the processed order by utilizing the services of services component 202. The notification may include sending an email notification to the customer with details of the processed order. The email notification may also include deployment information related to the order to enable the customer to access the subscribed services.
[0089] In certain embodiments, TAS module 204 may provide one or more TAS Application Programming Interfaces (APIs) 318 that enable TAS module 204 to interact with other modules in cloud infrastructure system 100 and for other modules to interact with TAS module 204. For example, the TAS APIs may include a system provisioning API that interacts with SDI module 206 via an asynchronous Simple Object Access Protocol (SOAP) based web services call to provision resources for the customer's subscription order. In one embodiment, TAS module 204 may also utilize the system provisioning API to accomplish system and service instance creation and deletion, switch a service instance to an increased service level, and associate service instances. An example of this is the association of a Java service instance to a fusion applications service instance to allow secure web service communications. The TAS APIs may also include a notification API that interacts with the services module 202 to notify the customer of a processed order. In certain embodiments, the TAS module 204 also periodically propagates subscription information, outages, and notifications (e.g. planned downtime) to services component 202.
[0090] In certain embodiments, TAS module 204 periodically receives usage statistics for each of the provisioned services such as the amount of storage used, the amount data transferred, the number of users, and the amount of system up time and system down time from EM module 208. Overage framework 322 utilizes the usage statistics to determine whether over use of a service has occurred, and if so, to determine how much to bill for the overage, and provides this information to order management module 214.
[0091] In certain embodiments, TAS module 204 includes an order workflow identification module 324 that is configured to identify one or more workflows associated with processing a customer's subscription order. In certain embodiments, TAS module 204 may include a subscription order generation framework 326 for generating subscription orders for a customer when the customer places a subscription order for one or more services offered by the cloud infrastructure system 100. In one embodiment, a subscription order includes one or more service components responsible for providing the services requested by a customer in the subscription order.
[0092] Additionally, TAS module 204 may also interact with one or more additional databases such as a Tenant Information System (TIS) database 320 to enable the provisioning of resources for one or more services subscribed by the customer while taking into consideration historical information, if any, available for the customer. TIS database 320 may include historical order information and historical usage information pertaining to orders subscribed by the customer.
[0093] TAS module 204 may be deployed using different deployment models. In certain embodiments, the deployment includes a central component that interfaces with one or more distributed components. The distributed components may, for example, be deployed as various data centers and accordingly may also be referred to as data center components. The central component includes capabilities to process orders and co-ordinate services in cloud infrastructure system 100, while the data center components provide capabilities for provisioning and operating the runtime system that provides the resources for the subscribed services.
[0094] FIG. 4 depicts an exemplary distributed deployment of the TAS module, according to an embodiment of the present invention. In the embodiment depicted in FIG. 4, the distributed deployment of TAS module 204 includes a TAS central component 400 and one or more TAS Data Centers (DCs) components 402, 404 and 406. These components may be implemented in hardware, or software, or combinations thereof.
[0095] In one embodiment, the responsibilities of TAS central component 400 include, without limitation, to provide a centralized component for receiving customer orders, performing order-related business operations such as creating a new subscription, changing the service level for a service in the subscription, changing the services included in the subscription, and extending the time period of the subscription, or canceling the subscription. The responsibilities of TAS central component 400 may also include maintaining and serving subscription data needed by cloud infrastructure system 100 and interfacing with order management module 214, support UI 216, cloud UI 212 and store UI 210 to handle all the back-office interactions.
[0096] In one embodiment, the responsibilities of TAS DCs 402, 404 and 406 include, without limitation, performing runtime operations for orchestrating the provisioning the resources for one or more services subscribed by the customer. TAS DCs 402, 404 and 406 also include capabilities to perform operations such as locking, unlocking, enabling, or disabling a subscription order, collecting metrics related to the order, determining the status of the order, and sending notification events related to the order.
[0097] In an exemplary operation of the distributed TAS system shown in FIG. 4, TAS central component 400 initially receives an order from a customer via cloud UI 212, store UI 210, via order management system 214, or via order database 224. In one embodiment, the customer represents a buyer who has financial information and the authority to order and/or change a subscription. In one embodiment, the order information includes information identifying the customer, the type of services that the customer wishes to subscribe to, and an account administrator who will be responsible for handling the request. In certain embodiments, the account administrator may be nominated by the customer when the customer places an order for a subscription to one or more services offered by cloud infrastructure system 100. Based on the order information, the TAS central component 400 identifies the data region of the world such as Americas, EMEA, or Asia Pacific in which the order originates and the particular TAS DCs (for e.g., 402, 404 or 406) that will be deployed for provisioning the order. In one embodiment, the particular TAS DC (for e.g., from among DCs 402, 404 or 406) that will be deployed for provisioning the order is determined based on the geographical data region in which the request originated.
[0098] TAS central component 400 then sends the order request to the particular TAS DC in which to provision services for the order request. In one embodiment, TAS DCs 402, 404 or 406 identify a service administrator and an identity domain administrator responsible for processing the order request at the particular TAS DC. The service administrator and the identity administrator may be nominated by the account administrator identified in the subscription order. TAS DCs 402, 404 or 406 communicate with SDI module 204 to orchestrate the provisioning of physical resources for the order. SDI component 204 in respective TAS DCs 402, 404 or 406 allocates resources and configures those resources needed to fulfill the subscription order.
[0099] In certain embodiments, TAS DCs, 402, 404 or 406 identify an identity domain associated with the subscription. SDI component 206 may provide the identity domain information to IDM component 200 (shown in FIG. 2) for identifying an existing identity domain or creating a new identity domain. Once the order is provisioned by the SDI module at respective TAS DCs, 402, 404 or 406, TAS central component 400 may place information regarding the provisioned resources in a support system, via support UI 216. Information may include, for example, displaying resource metrics related to the services and usage statistics of the services.
[0100] Once in operation, at each data center, EM module 208 to periodically collects usage statistics for each of the provisioned services provisioned at that data center, such as the amount of storage used, the amount data transferred, the number of users, and the amount of system up time and system down time. These statistics are provided to the TAS DC that is local to EM module 208 (i.e., at the same data center). In an embodiment, the TAS DCs may use the usage statistics to determine whether overuse of a service has occurred, and if so, to determine how much to bill for the overage, and provide the billing information to order management system 214.
[0101] FIG. 5 is a simplified block diagram illustrating the interactions of the SDI module with one or more modules in the cloud infrastructure system, in accordance with an embodiment of the present invention. In one embodiment, SDI module 206 interacts with TAS module 204 to provision resources for services in a subscription order received by TAS module 204. In certain embodiments, one or more of the modules illustrated in FIG. 5 may be modules within cloud infrastructure system 100. In other embodiments, one or more of the modules that interact with SDI module 206 may be outside cloud infrastructure system 100. In addition, alternative embodiments may have more or less modules than those shown in FIG. 5. These modules may be implemented in hardware, or software, or combinations thereof.
[0102] In one embodiment, the modules in SDI module 206 may include one or more modules in SaaS platform 102 and PaaS platform 104 in cloud infrastructure system 100. In order to perform provisioning of resources for various services, SDI module 206 may interact with various other modules, each customized to help with provisioning resources for a particular type of service. For example, as illustrated in FIG. 5, SDI module 206 may interact with a Java service provisioning control module 500 to provision Java cloud services. In one embodiment, Java service provisioning control component 500 may deploy a Java Cloud Service (JCS) assembly specified by SDI module 206 that includes a set of tasks to be performed to provision Java cloud services. Infrastructure resources 106 then determines the resources needed to provision the Java cloud services.
[0103] As other examples, SDI module 206 may interact with one or more modules such as a Virtual Assembly Builder (VAB) module 502, an Application Express (APEX) deployer module 504, a Virtual Machine (VM) module 506, an IDM module 200, and a database machine module 118. VAB module 502 includes capabilities to configure and provision complete multi-tier application environments. In one embodiment, VAB module 502 deploys a Middleware (MW) service assembly specified by SDI module 206 to provision a MW service in cloud infrastructure system 100 using the services provided by VM module 506. APEX deployer module 504 includes capabilities to configure and provision database services. In one embodiment, APEX deployer module 504 deploys a database service assembly specified by SDI module 206 to provision a database service in cloud infrastructure system 100 using the resources provided by infrastructure resources 106. SDI module 206 interacts with IDM module 200 to provide identity services such as access management across multiple applications in cloud infrastructure system 100.
[0104] FIG. 6 depicts a simplified high level diagram of sub-modules of the SDI module according to an embodiment of the present invention. In the embodiment depicted in FIG. 6, SDI module 206 includes a SDI-Web Services (WS) module 600, an SDI request controller module 602, an SDI task manager module 604, an SDI monitoring module 606, an SDI data access module 608, an SDI common library module 610, and an SDI connector module 612. These modules may be implemented in hardware, or software, or combinations thereof SDI module 206 depicted in FIG. 6 and its various modules are meant for illustrative purposes only and are not intended to limit the scope of embodiments of the present invention. Alternative embodiments may have more or less modules than those shown in FIG. 6. These modules and their functions are described in detail below.
[0105] SDI-WS module 600 includes capabilities for receiving a step in the business associated with an order from business process executor 316 of TAS component 204. In one embodiment, SDI-WS module 600 parses each step of the business process and converts the step into an internal representation used by SDI module 206. In one embodiment, each step of the business process associated with the order arrives through a web service processing layer (for example, via System Provisioning API discussed in FIG. 3B) in the form of a SOAP request to SDI-WS module 600.
[0106] SDI request controller module 602 is the internal request processing engine in SDI module 206 and includes capabilities for performing asynchronous request processing, concurrent request processing, concurrent task processing, fault tolerant and recovery and plug-in support related to the order requests. In one embodiment, SDI request controller module 602 accepts each step of the business process associated with the order from SDI-WS module 600 and submits the step to SDI task manager module 604.
[0107] SDI task manager module 604 translates each step specified in the business process into a series of tasks for provisioning the particular step. Once the set of tasks for a specific step have been provisioned, SDI task manager module 604 responds to business process executor 316 in TAS module 204 with operation results that includes an order payload with details of the resources provisioned to fulfill the particular step. SDI task manager module 604 repeats this process until all the steps of the particular business process associated with the order are complete.
[0108] In certain embodiments, SDI task manager module 604 translates each step specified in the business process into a series of tasks by utilizing the services of SDI connector module 612. SDI connector module 612 includes one or more connectors for handling the deployment of tasks specified by SDI task manager module 604 to provision one or more services related to the order request. In certain embodiments, one or more of the connectors may handle tasks that are specific to a particular service type while other connectors may handle tasks that are common across different service types. In one embodiment, SDI connector module 612 includes a set of connectors (wrapper APIs) that interface with one or more of the external modules (shown in FIG. 5) in cloud infrastructure system 100 to provision the services and resources related to the order request. For example, Application Express (APEX) connector 614 interfaces with APEX deployer module 504 to provision database services. Web Center Connector 616 (WCC) interfaces with a web center module in cloud infrastructure system 100 to provision web services. The web center module is a user engagement platform and includes capabilities for delivering connectivity between people and information in cloud infrastructure system 100.

NUVIAQ connector 620 interfaces with VAB module 502 to provision Java services. IDM connector 622 interfaces with IDM module 200 to provide identity and access management for users subscribing to services and resources in cloud infrastructure system 100. Virtual Assembly Builder (VAB) connector 624 interfaces with VAB module 502 in cloud infrastructure system 100 to configure and provision complete multi-tier application environments. Plug-in connector 626 interfaces with EM module 208 to manage and monitor the components in cloud infrastructure system 100. HTTP server connector 628 interfaces with one or more web servers in the PaaS platform to provide connection services to users in cloud infrastructure system 100.
[0110] SDI monitoring module 606 in SDI module 206 provides an inbound interface for receiving Java Management Extensions (JMX) requests. SDI monitoring module 606 also provides tools for managing and monitoring applications, system objects and devices in cloud infrastructure system 100. SDI-data access module 608 provides an inbound interface for receiving Java Database Connectivity (JDBC) requests. SDI-data access module 608 supports data access and provides object relational mapping, java transaction API services, data access objects, and connection pooling in cloud infrastructure system 100. The SDI-common library module 610 provides configuration support for the modules in SDI module 206.
[0111] The embodiment of FIG. 6 discussed above describes modules in the SDI module according to an embodiment of the present invention. FIG. 7A depicts a simplified flowchart 700 depicting processing that may be performed by the modules of the SDI module in the cloud infrastructure system, in accordance with an embodiment of the present invention. The processing depicted in FIG. 7A may be implemented in software (e.g., code, instructions, program) executed by one or more processors, hardware, or combinations thereof. The software may be stored in memory (e.g., on a memory device, on a non-transitory computer-readable storage medium). The particular series of processing steps depicted in FIG. 7A is not intended to be limiting. Other sequences of steps may also be performed according to alternative embodiments. For example, alternative embodiments of the present invention may perform the steps outlined above in a different order. Moreover, the individual steps illustrated in FIG. 7A may include multiple sub-steps that may be performed in various sequences as appropriate to the individual step. Furthermore, additional steps may be added or removed depending on the particular applications. One of ordinary skill in the art would recognize many variations, modifications, and alternatives. In one embodiment, the processing depicted in FIG. 7A may be performed by one or more modules in the SDI module 206 discussed in detail in FIG. 6.
[0112] At 702, a business process associated with a subscription order is received. In one embodiment, SDI-WS module 600 in SDI module 206 receives one or more steps in the business process associated with the subscription order from business process executor 316. At 704, each step in the business process is translated into a series of tasks for provisioning resources for the subscription order. In one embodiment, SDI task manager module 604 in SDI module 206 translates each step specified in the business process into a series of tasks by utilizing the services of SDI connector module 612. At 706, the subscription order is provisioned based on the series of tasks. In one embodiment, and as discussed in FIG. 6, SDI connector module 612 includes one or more connectors for handling the deployment of tasks specified by SDI task manager module 604 to provision resources for the services in the subscription order.
[0113] As described above with respect to FIG. 6, SDI task manager module 604 translates each step specified in a business process into a series of tasks by utilizing the services of SDI connector module 612, which may include one or more connectors for handling the deployment of tasks specified by SDI task manager module 604 to provision one or more services related to the order request. One or more of the connectors may handle tasks that are specific to a particular service type while other connectors may handle tasks that are common across different service types. In one embodiment, SDI connector module 612 includes a set of connectors (wrapper APIs) that interface with one or more of the external modules (shown in FIG. 5) in cloud infrastructure system 100 to provision the services and resources related to the order request. For example, a NUVIAQ connector 620 interfaces with VAB module 502 to provision Java services.
[0114] FIG. 7B depicts a simplified block diagram showing the high-level architecture of a Nuviaq system 710 and its relationships with other cloud infrastructure components according to an embodiment of the present invention. It should be appreciated that Nuviaq system 710 depicted in FIG. 7B may have other components than those depicted in FIG. 7B. Further, the embodiment shown in FIG. 7B is only one example of a cloud infrastructure system that may incorporate an embodiment of the invention. In some other embodiments, Nuviaq system 710 may have more or fewer components than shown in FIG. 7B, may combine two or more components, or may have a different configuration or arrangement of components.
[0115] In certain embodiments, Nuviaq system 710 may be configured to provide a runtime engine for orchestrating PaaS operations. Nuviaq system 710 may provide a web service API to facilitate integration with other products and services. Nuviaq system 710 also provides support for complex workflows in system provisioning, application deployment and associated lifecycle operations and integrates with management and monitoring solutions.
[0116] In the embodiment depicted in FIG. 7B, Nuviaq system 710 comprises a Nuviaq proxy 712, a Nuviaq manager 714, and a Nuviaq database 716. In certain embodiments, Nuviaq manager 714 provides an entry point into Nuviaq system 710, providing secure access to PaaS operations via the web service API. Internally, it tracks system state in the database and controls job execution on the workflow engine. In a public cloud, Nuviaq manager 714 may be accessed by the Tenant Provisioning system (SDI 206) and the Tenant Console, to drive provisioning and deployment operations respectively.
[0117] In one embodiment, Nuviaq manager 714 executes jobs asynchronously via an internal workflow engine. A job may be a sequence of actions specific to a given PaaS workflow. Actions may be performed in order, with failure in any step resulting in failure of the overall job. Many workflow actions delegate to external systems relevant to the workflow, such as the EM command line interface (cli). In one implementation, Nuviaq manager 714 application may be hosted in a 2-node WebLogic cluster with associated HTTP server (e.g., Oracle HTTP Server or OHS) instance, running inside a firewall.
[0118] In certain embodiments, Nuviaq proxy 712 is the public access point to the Nuviaq API. In one embodiment, only Public API may be exposed here. Requests received by proxy 712 may be forwarded to Nuviaq manager 714. In one embodiment, Nuviaq proxy 712 runs outside the firewall, whereas manager 714 runs within the firewall. In one implementation, Nuviaq proxy 712 application runs on a WebLogic cluster running outside the firewall.
[0119] In certain embodiments, Nuviaq database 716 tracks various domain entities such as, without limitation, platform instance, deployment plan, application, WebLogic domain, jobs, alerts, and the like. Primary keys may be aligned with the Service Database where appropriate.
[0120] In one embodiment, Platform Instance 718 may contain all resources required for a WebLogic service for a given tenant.
[0121] Nuviaq system 710 may rely on additional systems of cloud infrastructure system 100 to carry out the workflows used the WebLogic cloud service. These dependencies may include dependencies on SDI 206, IDM 200, a virus scan system, a service database, CRM instances, and the like. For example, Nuviaq system 710 may depend upon functions performed by an Assembly Deployer in SDI 206. In one embodiment, the Assembly Deployer is a system to manage interactions with OVAB (Oracle Virtual Assembly Builder) and OVM (Oracle Virtual Machine). Capabilities of the Assembly Deployer used by Nuviaq system 710 may include, without limitation, functions for deploying an assembly, un-deploying an assembly, describing assembly deployment, scaling appliance, and the like. In one implementation, Nuviaq system 710 accesses the Assembly Deployer via a web service API.
[0122] In certain embodiments, security policies may require certain artifacts to be scanned for viruses before being deployed to an application. Cloud infrastructure system 100 may provide a virus scan system for this purpose that provides scanning as a service for multiple components of the public cloud.
[0123] In certain embodiments, a public cloud infrastructure may maintain a Service Database containing information about tenants (e.g., customers) and their service subscriptions. Nuviaq workflows may access to this data in order to properly configure a WebLogic service as a client to other services that the tenant also subscribes to.
[0124] Nuviaq system 710 may depend on IDM 200 for its security integration. In certain embodiments, Java Service instances can be associated with a CRM instance. The association allows user applications deployed to their Java Service instance to access a CRM instance though Web Service calls.
[0125] Various entities may use services provided by Nuviaq system 710. These clients of Nuviaq system 710 may include: a Tenant Console, which is an management server (e.g., Oracle Management Server) based user interface that customers may access to manage their applications on their platform instances; several IDEs such as Oracle IDEs (JDeveloper, NetBeans, and OEPE) have been extended to offer access to application lifecycle management operations; one or more Command Line Interfaces (CLIs) that are available to access lifecycle operations on the platform instances.
[0126] Provisioning use case for Nuviaq system 710--A Provision Platform Instance use case is realized via the Create Platform Instance operation of the Nuviaq API. In the context of cloud infrastructure system 100, a service instance with respect to the Nuviaq system corresponds to a Nuviaq platform instance. A platform instance is assigned a unique identifier is used on all subsequent operations related to this instance. A Platform Deployment descriptor provided to the Create Platform Instance action allows for properties to be set that modify the configuration of the platform instance to meet the subscription requirements of the tenant. These properties may include for example:
[0127] Values: BASIC, STANDARD, ENTERPRISE
[0128] Description: Specifies the subscription type. This impacts the number of servers, database limits and quality of service settings. Property #2: oracle.cloud.service.weblogic.trial
[0129] Values: TRUE, FALSE
[0130] Description: Indicates whether or not this is a trial subscription. Property #3: oracle.cloud.service.weblogic.crm
[0131] Values: CRM Service ID
[0132] Description: Identifies a CRM service to be associated with this WebLogic service instance.
[0133] FIG. 7C depicts an example sequence diagram illustrating steps of a provisioning process using a Nuviaq system according to an embodiment of the present invention. The sequence diagram depicted in FIG. 7C is only an example and is not intended to be limiting.
[0134] Install/Update Application use case--The Install Application operation deploys an application to a running WebLogic Server after validating that the application archive meets the security requirements of the Public Cloud. In one embodiment, the Application Deployment descriptor provided to the Install Application action allows for properties to be set that modify the configuration of the application to meet the subscription requirements of the tenant. These properties may include for example:
[0135] Description: Specifies the initial state of the application after deployment.
[0136] FIG. 7D depicts an example sequence diagram illustrating steps of a deployment process using a Nuviaq system according to an embodiment of the present invention. The sequence diagram depicted in FIG. 7D is only an example and is not intended to be limiting.
[0137] Referring back to FIG. 2, in certain embodiments, TAS 204 and SDI 206 working in cooperation are responsible for provisioning resources for one or more services ordered by a customer from a set of services offered by cloud infrastructure system 100. For example, in one embodiment, for provisioning a database service, the automated provisioning flow may be as follows for a paid subscription:
[0138] In some embodiments, a customer may also be allowed to subscribe to a service on a trial basis. For example, such a trial order may be received via cloud UI 212 (e.g., using cloud.oracle.com).
[0139] In certain embodiments, cloud infrastructure system 100 enables underlying hardware and service instances to be shared between customers or tenants. For example, the database service may be provisioned as shown in FIG. 7E in one embodiment. FIG. 7E depicts multiple Exadata compute nodes 730 and 732, each providing a database instance provisioned for the database service. For example, compute node 730 provides a database instance 734 for a database service. Each Exadata compute node may have multiple database instances.
[0140] In certain embodiments, each database instance can comprise multiple schemas and the schemas may be associated with different customers or tenants. For example, in FIG. 7E, database instance 734 provides two schemas 736 and 738, each with its own tables. Schema 736 may be associated with a first customer or tenant subscribing to a database service and schema 738 may be associated with a second customer or tenant subscribing to the database service. Each tenant gets a completely isolated schema. Each schema acts like a container that can manage database objects including tables, views, stored procedures, triggers, etc. for the associated tenant. Each schema may have one dedicated tablespace, with each tablespace having one data file.
[0141] In this manner, a single database instance can provide database services to multiple tenants. This not only enables sharing of underlying hardware resources but also enables sharing of service instance between tenants.
[0142] In certain embodiments, such a multi-tenancy system is facilitated by IDM 200, which beneficially enables multiple separate customers, each having their own separate identity domains, to use hardware and software that is shared in the cloud. Consequently, there is no need for each customer to have its own dedicated hardware or software resources, and in some cases resources that are not being used by some customers at a particular moment can be used by other customers, thereby preventing those resources from being wasted. For example, as depicted in FIG. 7E, a database instance can service multiple customers each with their respective identity domains. Although each such database service instance can be a separate abstraction or view of a single physical multi-tenant database system that is shared among the many separate identity domains, each such database service instance can have a separate and potentially different schema than each other database service instance has. Thus, the multi-tenant database system can store mappings between customer-specified database schemas and the identity domains to which those database schemas pertain. The multi-tenant database system can cause the database service instance for a particular identity domain to use the schema that is mapped to that particular identity domain.
[0143] The multi-tenancy can also be extended to other services such as the Java Service. For example, multiple customers can have a JAVA service instance placed within their respective identity domains. Each such identity domain can have a JAVA virtual machine, which can be viewed as being a virtual "slice" of hardware. In one embodiment, a job-monitoring service (e.g., Hudson) can be combined with a JAVA enterprise edition platform (e.g., Oracle WebLogic) in the cloud to enable each separate identity domain to have its own separate virtual "slice" of the JAVA enterprise edition platform. Such a job-monitoring service can, for example, monitor the execution of repeated jobs, such as building a software project or jobs run by an operating system's time-based job scheduler. Such repeated jobs can include the continuous building and/or testing of software projects. Additionally or alternatively, such repeated jobs can include the monitoring of executions of operating system-run jobs that are executed on machines that are remote from the machine on which the job-monitoring service executes.
[0144] Business Attribute Derived Sizing of Services
[0145] As discussed above, a customer may order one or more services provided by cloud infrastructure system 100 via a subscription order. Cloud infrastructure system 100 then performs processing to provide the services in the customer's subscription order. Provisioning of the services in the customer's subscription order by cloud infrastructure system 100 may comprise SDI module 206 allocating or provisioning individual components or multiple components which working in conjunction to provide an ordered service.
[0146] The order information received by cloud infrastructure system 100 in response to the customer placing an order may include information identifying the customer and one or more services offered by the cloud infrastructure system 100 that the customer intends to subscribe to. Additionally, the order may also include one or more service levels for the ordered services that determine the amount of resources to be allocated for providing the requested service in the context of the subscription, such as the amount of storage, amount of computing resources, data transfer facilities, and the like.
[0147] In some instances, the order information received by cloud infrastructure system 100 may include information indicative of a customer level, and the time period during which the service is desired. The customer level specifies the priority of the customer making the subscription request. In one example, the priority may be determined based on the quality of service that the cloud infrastructure system 100 guarantees or promises the customer as specified by a Service Level Agreement (SLA) agreed to between the customer and the provider of the cloud services. In one example, the different customer levels include a basic level, a silver level and a gold level. The time period for a service may specify the activation start date and time for the service and the time period for which the service is desired (e.g., a service deactivation date and time may be specified). Accordingly, in certain embodiments, cloud infrastructure system 100 sells cloud services for which a customer can make choices on what services the customer wants to order in addition to variety of service options.
[0148] In certain embodiments discussed above, TAS module 204 functions as an orchestration component that manages business processes associated with each order and applies business logic to determine whether an order should proceed to provisioning. In one embodiment, upon receiving an order for a new subscription, TAS module 204 sends a request to SDI module 206 to allocate resources and configure those resources needed to fulfill the subscription order. SDI module 206 enables the allocation of resources for the services ordered by the customer. SDI module 206 provides a level of abstraction between the cloud services provided by cloud infrastructure system 100 and the physical implementation layer that is used to provision the resources for providing the requested services. TAS module 204 may thus be isolated from implementation details such as whether or not services and resources are actually provisioned on the fly or pre-provisioned and only allocated/assigned upon request. The order information, therefore, is a source of a variety of business attributes that can be used to determine whether or not services and resources are actually provisioned on the fly or pre-provisioned and only allocated/assigned upon request in addition to how such services (whether pre-provisioned or not) are allocated and configured.
[0149] In one example, a customer accesses one or more portions of cloud infrastructure system 100 to sign up for one or more services, such as a Java service that includes one or more database components. In one aspect, cloud infrastructure system 100, using SDI module 206, may allocate one or more pre-provisioned database components to the customer's order in order to provide the requested Java service. For example, a service may be offered to a customer in various customer-selectable sizes or levels (e.g., small, medium, large). If the corresponding size for the customer's order is a trial of the Java Service, the trial may have its own size limits or requirements (e.g., a small level for the service rather than a large level) and a pre-provisioned component of appropriate size may be allocated to the clients order. SDI module 206 may drive a pre-provisioning background allocation and then select from existing pre-provisioned components at runtime. The allocation of pre-provisioned components facilitates order processing and allows the customer to begin using the desired service without waiting for the allocation of all resources needed for the ordered service.
[0150] In another aspect, SDI module 206 determines whether resources are actually provisioned on the fly or pre-provisioned and only allocated/assigned upon request and how to scale or configure components based on business attributes of order information received by cloud infrastructure system 100. For example, cloud infrastructure system 100 may provide a customer options for further configuring a service or its use as discussed above. Depending on service and options selected, SDI module 206 may determine whether resources are actually provisioned on the fly or pre-provisioned and only allocated/assigned upon request and how to scale or configure components according to the customer's options. Scale out features of SDI module 206 thus can be configurable wherein a weighted algorithm can be used to compute the number of scale-out nodes.
[0151] For some services, how SDI module 206 may allocates resources may be determined in a straightforward manner based on one or more business models that explicitly define resource levels or sizes for a service. Levels or sizes of services in business models can be derived based on an organization's dictates of how customers should use resources, information gathered about actual usage, and the like. An organization may desire a deterministic pattern for resource allocation that simplifies resource accounting, efficiently allocates resources, and reduces resource underutilization.
[0152] Thus, a business model, in general, provides an indication of any of limits on the amounts of resources allocated to a customer for providing a service. In one aspect, limits of a model may be set based on arbitrary criteria, such as those derived from market forces, recommendations from customers, and the like. In another aspect, limits of a business model may be set based on information obtained from actual or projected usage, such as through information obtained from performance, scalability and reliability (PSR) testing. A variety of business models can provide the deterministic pattern for resource allocation that simplifies management.
[0153] For some services (especially for SaaS services), in the alternative to or in connection with one or more business models, a set of one or more variables are used to control the how the deterministic pattern for resource allocation of the one or more business models are actually implemented. In some embodiments, services are sized based on aspects, attributes, or options selected in the order information for a given service. In other embodiments, pre-provisioned components associated with a service that conform to one or more business model are allocated or configured based on aspects, attributes, or options selected in the order information for the given service. For example, cloud infrastructure system 100 may allow a customer to make all sorts of choices during ordering. A customer may specify what services, modules, and applications they want to order. Additionally a customer may specify how many user accounts will be needed for which modules, what additional features a component is to offer, redundancy or high availability options, what additional resources are needed, what levels of service are expected beyond those offered, and the like. SDI module 206 determines whether resources are actually provisioned on the fly or pre-provisioned and only allocated/assigned upon request and how to scale or configure components using one or a combination of business models and business attributes in the order information.
[0154] FIG. 8 depicts a simplified high level diagram of sub-modules of SDI module 206 for sizing services according to an embodiment of the present invention. In the embodiment depicted in FIG. 8, SDI module 206 includes an SDI sizing module 800. SDI Sizing model may be a separater module from those depicted in FIG. 6 or may be included in one or more of the depicted modules and/or in SDI common library 610. In one embodiment, SDI sizing module 800 forms part of SDI task manager module 604. In another embodiment, SDI sizing module 800 communicates with SDI task manager module 604 to provide sizing information allowing SDI task manager module 604 to translate each step specified in a business process into a series of tasks for provisioning the particular step.
[0155] SDI sizing module 800 includes one or more mapping rules. A mapping rule maps business attributes to a predetermined resource configuration. As discussed above, when ordering a service to provide an application, a customer may specify the number of users that the customer is willing to pay for licenses to use the application. One or more mapping rules assocaited with the application may include information that maps the number of users requested to a set of resource allocations. For example, 0-10 users may only require 1 virtual machine configured in a predetermined manner to host the application with no need for redudancy or hi-availability. In another example, 1001+ users may require 10 or more virtual machines configured to a predetermined manner to host the application together with redudnancy and hi-availabilty features enabled.
[0156] Continuing the trial example from above, SDI module 206 may pass one or more attributes derived from a business process associated with an order to SDI sizing module 800. SDI sizing module 800 may apply a set of mapping rules to the one or more attributes to provide sizing information to SDI module 206. SDI module 206 may utilize the sizing information directly or indirectly when translating each step specified in the business process into a series of tasks for each step to enable the allocation of resources for the services ordered by the customer.
[0157] FIG. 9 depicts a simplified flowchart 900 depicting processing that may be performed by the modules of the SDI module in the cloud infrastructure system for sizing services, in accordance with an embodiment of the present invention. The processing depicted in FIG. 9 may be implemented in software (e.g., code, instructions, program) executed by one or more processors, hardware, or combinations thereof. The software may be stored in memory (e.g., on a memory device, on a non-transitory computer-readable storage medium). The particular series of processing steps depicted in FIG. 9 is not intended to be limiting. Other sequences of steps may also be performed according to alternative embodiments. For example, alternative embodiments of the present invention may perform the steps outlined above in a different order. Moreover, the individual steps illustrated in FIG. 9 may include multiple sub-steps that may be performed in various sequences as appropriate to the individual step. Furthermore, additional steps may be added or removed depending on the particular applications. One of ordinary skill in the art would recognize many variations, modifications, and alternatives. In one embodiment, the processing depicted in FIG. 9 may be performed by one or more modules in the SDI module 206 discussed in detail in FIGS. 6 and 8.
[0158] At 902, performance, scalability, and reliability (PSR) information is received. The PSR information generally provides the amount of resources needed to satisfy a given business scenario. For example, the PSR information may indicate that X number of resources is needed for every Y number of users. In another example, the PSR information may indicate that X number of resources is needed for every Y number of users of Z application having redundancy, hi-availability, or other SLA options. Additional variations on the above can be indicated according to other variables or factors. For example, administrators of a cloud infrastructure system (e.g., cloud infrastructure system 100) may identify key or important metrics to providing a service estimate the amount of resourced needed to achieve the metrics. Furthermore, key or important metrics may correlate to the manner tracked or in which resources are actually used. In one aspect, the PSR information may identify business workflows, necessary data, system configuration(s), and machine requirements that describe or provide an indication of the amount of resources used or needed for a component or set of components given a variety of levels of options, availability, or other criteria.
[0159] At 904, one or more business models is received. As discussed above, a business model provides an indication of any of limits on the amounts of resources allocated to a customer for providing a service. Such limits may be in terms of a lower or upper bound, as well as being an absence of a limit on a given resource. In some embodiments, a business model provides default settings or common settings for a component. In one aspect, a business model may provide how the organization selling cloud services associated with cloud infrastructure system 100 seeks to offer a given service (e.g., what are the predefined limits on the amount of resources). In another aspect, a business model may fix the amount of some resources and allow amounts of other resources to be scaled or sized based on a customer's order.
[0160] At 906, one or more size mapping rules are generated based on the PSR information and the one or more business models. In general, each mapping rule maps one or more business attributes to resource provisioning information. For example, a mapping rule may indicate that a customer request for 1000 users for a CRM application requires or needs 4 virtual machines. In another example, a mapping rule may indicate that a customer request for 100 users for a predetermined application also needs 4 virtual machines because the nature of the application. A mapping rule may map one business attribute to a set of provisioning information for a set of components. A mapping rule may further map a plurality of business attributes to provisioning information for one component. A mapping rule may also include one or more conditions that need to be satisfied in order for the rule to apply, logic for manipulating or performing calculations of key-value pairs of business attributes, business logic, and the like.
[0161] The following XML document provides an example of one or more mapping rules generated according to the present invention. The XML document may be used to configure SDI sizing module 800 and/or SDI task manager module 604. In this example, each service is provided with a weighting factor that enables SDI task manager module 604 to determine to amount of resources that need to be provisioned based on a determine number of user. The following example is merely explanatory and should be not be seen as limiting in any way. It will be apparent that weighting factors can be applied to other business attributes other than a requested number of user as well as information derived from these other attributes.

[0163] FIG. 10 depicts a simplified flowchart depicting processing that may be performed by the modules of the SDI module in the cloud infrastructure system for generating configuration information based on business attributes, in accordance with an embodiment of the present invention. The processing depicted in FIG. 10 may be implemented in software (e.g., code, instructions, program) executed by one or more processors, hardware, or combinations thereof. The software may be stored in memory (e.g., on a memory device, on a non-transitory computer-readable storage medium). The particular series of processing steps depicted in FIG. 10 is not intended to be limiting. Other sequences of steps may also be performed according to alternative embodiments. For example, alternative embodiments of the present invention may perform the steps outlined above in a different order. Moreover, the individual steps illustrated in FIG. 10 may include multiple sub-steps that may be performed in various sequences as appropriate to the individual step. Furthermore, additional steps may be added or removed depending on the particular applications. One of ordinary skill in the art would recognize many variations, modifications, and alternatives. In one embodiment, the processing depicted in FIG. 10 may be performed by one or more modules in the SDI module 206 discussed in detail in FIGS. 6 and 8.
[0164] At 1002, an order payload is received. For example, SDI sizing module 800 communicates with SDI task manager module 604 when translating each step specified in a business process into a series of tasks for provisioning the particular step. The following is an example of an order payload to be used with reference to FIG. 10.

[0165] At 1004, components satisfying a set of mapping rules are determined. In one embodiment, SDI sizing module 800 checks whether a component identifier specified the order payload matches with the one specified in the set of mapping rules. SDI sizing module 800 may use a lookup table or other data structure to optimize searches for matching components in the mapping rules. The following is an example of a set of mapping rules to be used with reference to FIG. 10.

[0166] In various embodiments, SDI sizing module 800 may be configured to check an initial set of attributes of a matching component to derive a subsequent set of attributes. SDI sizing module 800 may determine a total or combination of values of attributes that have been weighted by the mapping rules to output resource provisioning information.
[0167] For example, returning to FIG. 10, at 1004, if there is a component match, SDI sizing module 800 checks if the IS_BASE_SERVICE_COMPONENT property is set to true. If IS_BASE_SERVICE_COMPONENT is set to true, SDI sizing module 800 checks for the value of the METRIC_NAME property. The value of the METRIC_NAME property specifies which business attributes SDI sizing module 800 utilizes in generating sizing information. For example, the value of the METRIC_NAME property becomes a key to determine from where SDI sizing module 800 derives the information to drive a scaling decision. The value of the properties can be multiplied with a weightage factor to arrive at a decision on the amount of resources needed.
[0168] In this example, if the value of the METRIC_NAME key-value pair is HOSTED_NAMED_USER, then the value of the HOSTED_NAMED_USER property in the order payload will be taken to be scaled according to a weightage factor in one or more corresponding mapping rules.
[0169] At 1006, weighting values for components are determined. In one aspect, totals are obtained from all scaled factors and may be consolidated to determine a corresponding scaling factor. Reference the above XML example, SDI sizing module 800 scales out nodes as follows:
User Count Calculation for service component with component_id 7500003 is 100. 100*1 (weightage for service component with component_id 7500003)=100 User Count Calculation for component id 7500062 which is under the service component with component_Id 7500003 Is 100*2 (weightage for component with component_Id 7500062=200 Consolidated user count=100+200=300 Number of scale out nodes assigned for user count 200=4
[0170] In one example, the consolidated user count is matched against its appropriate service configuration from the XML and the corresponding scale cut factor is fetched. In some aspects, during update orders, since the input payload may include an absolute metric value, the scale out nodes may be assigned after subtracting from the already scaled nodes. For example, if during onboarding an order for HCM, the user count is 1000, the number of scale cut nodes assigned will be 4 (as defined in the configuration). If an update order for the above subscription which has user count as 2500, the number of nodes will be 8. Exira nodes that needs to be scaled cut is 8 (as calculated from the update order)-4 (already assigned scale nodes during create order)=4. Thus, the update payload from TAS contains the union of service components present in the update order plus the onboarding order.
[0171] In one aspect, for update orders, the request payload passed to SDI may contain the absolute user count for each component and not the delta user count. For example, an onboarding order may have a service component A and a metric value calculation that is is completed and persisted in a DB. For an update order, in which service component B is getting updated with a new metric value, the update payload from TAS may contain the information about both the service component A and service component B.
[0172] At 1008, configuration information is generated. In this example, SDI sizing module 800 generates information based on the weighting values that can be used by SDI task manager module 604 to translate each step specified in a business process into a series of tasks for provisioning the particular step. In some embodiments, SDI sizing module 800 directly generates the actual amount of resources that SDI module 206 may allocate and configure to fulfill a customer's subscription order. In other embodiments, SDI sizing module 800 generates one or more recommendations for the amount of resources that SDI module 206 may use to actually allocate and configure to fulfill a customer's subscription order.
[0173] In one embodiment, templates are provided that enable the SDI to determine the size of a service for a particular service order. The SDI may also use a template to determine the resources to be allocated for the customer. SDI uses various sizing algorithms using templates and lookup tables for abstract outsizing mapping to various resources (e.g., VM machines) representing different components that interact together for applications. In one embodiment, the templates are used to map attributes associated with an order to resources to be provisioned for the order. In some embodiments, a base set of resources may be determined (potentially using a mapping template) and then additional resource to be provisioned may be determined using one or more templates.
[0174] The sizing technique used by SDI may be used for a variety of services including but not limited to JCS+DB service, CRM, HCM, ERP, and the like. SDI may use the sizing techniques during Scale Up operations.
[0175] In some embodiments, a "high" threshold may be established for a service instance. If the size for a service instance is deemed by SDI to exceed this high threshold, then the customer may be prompted to order another service instance.
[0176] Depending upon the service, the resource allocation may be performed by SDI, by the service itself, or a combination of SDI and the service.
[0177] In one embodiment, SDI sizing module 800 may store a variety of configuration versions as well as a variety of configuration representing mapping rules. In one aspect, SDI sizing module 800 may include one or more tools that allow updating, modifying, or removing all or party of a configuration. In another aspect, SDI sizing module 800 may include one or more tools allowing manual scaling of resources.
