DETAILED DESCRIPTION
Techniques are described that may address a major roadblock in adopting the cloud based applications, for example, by allowing service based applications to operate without having clients to move to a public cloud. Instead applications can migrate to the client site and run in the native or private cloud environment. Such techniques may be implemented as a system, computer-implemented method and/or embodied in a computer program product. While the system and/or methodologies described in the present disclosure may be useful in healthcare applications, they are not limited to the applications in healthcare service industry. Rather, the techniques described herein may be utilized for providing any other services or applications, for example, where security of data and running applications is desired.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. The cloud model may include different characteristics, different service models and different deployment models.
A cloud computing environment is usually service oriented with a focus on statelessnesss, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes. It is understood in advance that although this disclosure may includes a description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments disclosed herein are capable of being implemented in conjunction with any other type of computing environment now known or later developed, as applicable.
In one embodiment, a methodology of the present disclosure may completely automate the process of downloading the application to an on premise hosted environment. In one aspect, the downloaded application may include an agent, which can run as a process on a computer, for example, a client computer. In one embodiment, the agent may create sandbox by downloading a virtual machine image to a client computer, setting up the virtual machine, and securely configuring it. A sandbox is an environment that is usually isolated from other components of a computing system, and communicates with the external world through well defined and monitored interfaces. Security software in the sandbox enforces policies that prevent unauthorized data to move out, and/or external applications to access the data. Applications or processes run in the sandbox may be restricted in what they can do. For example, the sandbox may allow for access to local data and provide a mechanism to prevent data from leaving the environment. In one aspect, the sandbox may include a protected set of computing resources (e.g., memory and disk storage) that are allocated and dedicated for a specific application. In one embodiment, the data loaded into the sandbox may be accessible only by the specific application and the specific mechanism the application uses.
The agent may install the application components such as database, visualization and analytics components. The agent may include a data harness and data description that starts to search and establish connectivity with the data registry to tap into enterprise data at the customer environment. The agent may include validation steps or processes capable of discovering the data and validating whether data requirement can be met. The agent may install one or more monitoring and metering apps (applications) that allows for “pay per use model” for the applications. Briefly, a “pay per use model” refers to a payment method in which a consumer pays a fee on per usage basis, e.g., every time the application or software is being used.
A methodology of the present disclosure in one embodiment may allow for a pay per use model to be provided at a customer environment. The methodology of the present disclosure in one embodiment may provide cost effective applications and reduce costs such as service and software costs (e.g., 20% services cost and 80% software cost). The methodology of the present disclosure in one embodiment may increase the number of application and analytics adoption. According to a methodology of the present disclosure in one embodiment, the customer data stays in their premise, and the application moves to the data. This provides a cost effective and easily deployable application, reducing the long delivery cycle of installing applications. A methodology of the present disclosure in one embodiment may allow the applications to be a part of the market place while maintaining the compliance and security of the data.
A methodology of the present disclosure in one embodiment may allow users (e.g., healthcare providers, clinical researchers) to download an application in their environment. A user or consumer can access a marketplace, (e.g., a cloud environment that may provide software as a service) to identify a set of applications the user would be interested in. The marketplace provides a framework to try and purchase a service of an application. A methodology of the present disclosure in one embodiment may also include a packaging construct that describes the data requirements for the downloaded application to run. For example, the data requirements may be described according to schemas and/or data formats.
Responsive to a user or consumer clicking on a buy or download option, a methodology of the present disclosure may trigger a set of provisioning tasks to download an application from a trusted server. Examples of provisioning tasks include installing software products and application components. A sandbox setup may be a one-time task at the user's environment, e.g., for a specific user. Provisioning tasks also include downloading an application into the user's environment (e.g., sandbox), and configuring it to work in the sandbox. An agent also instantiates an install process. The application may include a set of components, for example, visualization component, database component and analytics components.
The install process that is instantiated also runs a set of validation steps to verify, e.g., the installation process and runtime configuration parameters associated with the application. Prior to execution of the application, an agent process may perform data discovery and binding to existing data sources, e.g., enterprise data sources at the user's environment, that are needed to start using the application (also referred to as abstraction of data binding). The application is up and running after the install. The downloadable application also allows for metering, monitoring of the data consumption. In one aspect, initial setup may be performed at a user site from hardware and operating system perspective. For example, before an application can be downloaded and installed, a physical server may need to be setup and operating system may need to be installed. Further, the physical server may run a hypervisor environment, capable of running a virtual server from a virtual machine image.
FIG. 1 is a diagram illustrating a life cycle of an application in one embodiment of the present disclosure. An application may be developed by a developer, for example, using an application development workbench 102. For instance, an application code base 104 may be packaged as deployable artifacts 106 and published at a marketplace 108, for example, in a cloud computing environment 110 that offers the application to consumers or users, for example, as software as a service (SaaS). During the life cycle of an application, an application codebase 104 may be upgraded with patches, and upgraded application may be further packaged into deployable artifacts 106, and published 108 in a marketplace 110. An application development workbench 102 may include a tool that allows for creating applications and putting the applications in a marketplace 110. A marketplace 110, for example, may allow users or consumers to try, buy and/or upgrade an application as a service, and/or buy additional services. According to a methodology of the present disclosure in one embodiment, an application may be provisioned to a user's computing environment 112, and configured to run in a sandbox securely in the user's computing environment 112. A secured sandbox in one aspect provides access to customer data. An application may be installed in a sandbox automatically, for example, downloaded from a marketplace 110. A methodology of the present disclosure in one embodiment also provides one or more capabilities that can monitor and meter the usage of the application that is running within a sandbox in the user's computing environment 112, and also provides capabilities for data validation and analytics result validation.
FIG. 2 is a diagram illustrating an application delivery platform in one embodiment of the present disclosure. The application delivery platform may also apply to delivering applications to a complex computing customer or user environment. An application marketplace 202 may provide one or more applications that may be downloaded to a user's computing environment and still yet provided as a service, for example, Software-as-a-Service (SaaS) pay per use model. An application marketplace 202 may store or include a plurality of applications (e.g., 204) and services that are made available to consumers or users. An application (e.g., 204) may be automatically downloaded with an agent module or process that securely allows access to local data and prevents the data from leaving the application environment. An application (e.g., 204) may be migrated to a client site and run in a native environment and use data available locally, on a micro cloud, or private cloud. In this way, sensitive and or private data such as health related data, credit card data, need not move to the cloud. In one embodiment of the present disclosure, an agent that is downloaded with the application (e.g., 204) may create a sandbox 206 that is secure, and install the enterprise application components. The agent includes a data harness and data description that searches and establishes connectivity with the data registry in order to access data at the customer environment. The application components may include database component (e.g., shown as relational database as an example), analytics component 210, visualization and/or reporting component 212, and/or a scheduler component 214.
The plan-level visualization component 216, administration & governance component 218, analytics model, data script, report template components 220, 222 may be executed to configure the application components (e.g., 208, 210, 212, 214) to run securely within the sandbox 206 in a user's computing environment.
In one embodiment, a sandbox 206 may accommodate a plurality of applications 224. A sandbox, for example, may be provided per server. In another embodiment, a sandbox 206 may persist in a user's computing environment, even when an application 224 is no longer running in the user's computing environment (e.g., application service is no longer provided from the marketplace).
A sandbox 206 may also include functionalities that provide cloud-like capabilities 226 such as monitoring 226, metering 228, data validation 230, and analytics result validation 232. Monitor component or functionality 226 may continuously monitor the applications running in the sandbox. This mechanism in one embodiment may help to keep the applications up and running and provides real time alerts for fast resolution. Metering component 228 measures or computes the application usage, for example, for payment purposes, to allow paying for the application as a service. Data validation component or functionality 230 may discover and validate data requirements. For example, based on the data description requirement that is packaged with the application, the data validation component 230 may discover data in the enterprise data sources and validate to determine whether the enterprise data sources include the required data to run the application properly. For example, the data validation component 230 may use validation rules defined in the data dictionary of an application and validate rules such as valid data types, range and structure validation. Data discovery component searches against a pre-defined data directory and discovers the data. Analytics result validation component or functionality 232 may generate results such as prediction of future values and/or identify patterns from a dataset. Analytics validation component 232 helps to verify that the patterns that are produced by the analytics occur in the wider data set and is not biased.
The components or elements deployed in the sandbox 206 are executable components that run on one or more hardware processors. In one aspect, the monitoring component 226 may send the monitoring and metering information back to the cloud.
FIG. 3 is a diagram showing an application marketplace and delivery platform in one embodiment of the present disclosure. A developer may write or develop an application using a tool such as an application development workbench 302, and publish the application to a marketplace, e.g., cloud computing environment that offers applications as a service to a consumer or user 306. In one embodiment of the present disclosure as described above, one or more applications offered as a service may be downloaded from a marketplace 304 and run in a user's private computing environment securely, e.g., according to a sandbox methodology described with reference to FIG. 2.
FIG. 4 is a flow diagram illustrating a method of providing an application as a service securely in one embodiment of the present disclosure. The method in one embodiment automates application download and provides it as a service. At 402, a request for an application is received. For example, a request from a consumer or user to purchase an application to use as a service may be received at a computing environment that is providing a marketplace for offering one or more applications as a service. A user interface or like tool may be provided to the user for entering or selecting one or more applications to purchase and use as a service. For example, a browser or a web interface may be provided to a computing environment implementing the marketplace.
At 404, in response to the request, a set of provisioning tasks may be triggered to download the application. For example, at 406, a sandbox is created at the user's site, (e.g., user's computing environment that includes one or more processors and memory and other devices). In one embodiment, a sandbox includes a set of virtual machines.
The application includes an agent process that is triggered to create a secure sandbox in the user's computing environment and provision the application to run in the user's computing environment securely using the user's data. For example, in one embodiment, an agent component may be downloaded to the user's site and the agent runs to create a sandbox and instantiate installation and configuration of an application.
At 408, installation and instantiation of the application is automated. For example, the application is downloaded and configurations are setup to instantiate an install process for installing the application on the user's computing environment. For example, a set of relevant application components or parts may be downloaded into the sandbox designated to a user, the application components/parts may be dynamically composed, runtime configuration parameters may be applied, and the application may be initiated or invoked for execution within the designated and protected sandbox. Application components may include database, visualization and analytics components.
At 410, the method may include searching through existing data connectivity and tapping into enterprise data at the user's computing environment. For example, a data harness and data description component that is included in the application may search and establish connectivity with the data registry to tap into enterprise data at the user's computing environment.
FIG. 5 illustrates a schematic of an example computer or processing system that may implement a secure application provisioning system in one embodiment of the present disclosure.
