## Title
Mobile development platform in a cloud based architecture

## Abstract

Embodiments are directed towards mobile application development in a cloud-based architecture. Mobile applications may be designed to communicate with a cloud platform over a network. Mobile application developers may be enabled to submit cloud code to cloud platforms for use by mobile applications. If cloud code is provided to a cloud platform, the cloud platform may perform one or more actions to authenticate the cloud code, such as, ensuring that that the user providing the cloud code is authorized to provide the cloud code. If the cloud code is authenticated the cloud platform may perform one or more actions to validate the cloud code. If validated, the cloud code may be activated for use by mobile applications and/or mobile application developers. Activation of the cloud code may include associating the cloud code with one or more function calls and/or with one or more trigger points.

## Background
TECHNICAL FIELD
This invention relates generally to mobile application development in a cloud-based architecture, and more particularly, but not exclusively, to deploying mobile application code in a cloud-based environment.
BACKGROUND
As the popularity and complexity of mobile applications has increased, more mobile applications use application platforms to provide scalable functionality for their mobile applications. Application platforms may provide remote functionality, remote storage, or the like, that mobile applications may interact with over a network. In some cases, networks linking mobile applications and application platforms may be slow and/or unreliable. As a result, mobile application performance may suffer if interactions between mobile applications and application platforms increase in number and complexity.
Furthermore, as the complexity of mobile applications increases some may require custom services that may be difficult for an application platform to provide. If an application platform lacks sufficient features, mobile applications may be required to implement the feature locally on the mobile devices. Performing the additional tasks that may be required for complex applications at the mobile devices may require the use of more resources on the mobile device and increased network transactions between the mobile device and the application platform. Thus, it is with respect to these considerations and others that the present innovations have been made.

Briefly stated, various embodiments are directed towards mobile application development in a cloud-based architecture. In at least one of the various embodiments, mobile applications may be designed to communicate with a cloud platform over a network. In at least one of the various embodiments, mobile application developers may be enabled to submit cloud code to cloud platforms for use by mobile applications. If cloud code is provided to a cloud platform, the cloud platform may perform one or more actions to authenticate the cloud code, such as, ensuring that the user providing the cloud code is authorized to provide the cloud code. If the cloud code is authenticated, in at least one of the various embodiments, the cloud platform may perform one or more actions to validate the cloud code. If validated, the cloud code may be activated for use by mobile applications and/or mobile application developers. Activation of the cloud code may include associating the cloud code with one or more function calls and/or with one or more trigger points.
In at least one of the various embodiments, if the communication from the mobile application includes a function call rather than cloud code, the cloud platform may determine if the provided function call is associated with cloud code or if it is associated with a built-in cloud platform service. If the function call is associated with cloud code, the cloud platform may perform one or more actions to determine a sandbox residing on a cloud code server for executing the cloud code. If a suitable sandbox is available, the cloud platform may provide the cloud code to the sandbox for execution. The results of executing the cloud code in the sandbox may be provided to the mobile application that made the function call.
In at least one of the various embodiments, determining the sandbox for executing the cloud code may include performing one or more load balancing actions among the cloud code servers. In at least one of the various embodiments, cloud code servers may be in communication with the cloud platform and may be updating the cloud platform on their status and sandbox availability.
In at least one of the various embodiments, validating cloud code during deployment may include scanning the contents of the cloud code (e.g., source code) to detect if unsafe code may be included in the cloud code, Unsafe code may include instructions that may cause the problems for other sandboxes, cloud code servers, or the cloud platform. For example, unsafe instruction may include, potentially infinite loops, excessive recursion, attempting to access restricted resources, or the like. In at least one of the various embodiments, unsafe instructions may be determined by looking for known patterns in the source code of the cloud code.
In at least one of the various embodiments, sandboxes may include specially modified system calls that may transparently prevent the cloud code from exceeding resource thresholds. For example, memory allocation system calls may be modified to limit the amount of memory that can be allocation within various scopes, such as, per call, per process, per sandbox, per cloud code server, or the like. Such modifications may impose safety and performance quotes on resources that go beyond the standard features of the programming language/environment used by the cloud code.
In at least one of the various embodiments, one or more watcher processes may be employed to monitor the operations of the sandboxes and/or the cloud code servers. If non-performing sandboxes are discovered the watcher process may cause the sandbox to be reset/restarted. If non-performing cloud code servers are discovered they may be reset and/or rebooted. If function calls linked to cloud code are interrupted by resets, reboots, or timeouts, they may be retried by the cloud platform.

Illustrative Architecture for a Cloud-Based Developer Platform
In at least one of the various embodiments, a cloud platform may be a system that enables mobile application developers to enrich their mobile applications by accessing functions and services that may be provided by the cloud platform. Cloud platforms may provide a variety of predefined functions and API's that provide services useful to develop mobile applications. A cloud platform may provide API's that may be used in mobile application to provide services, such as, payment services, user management, data services (e.g., storage, searching, or the like), logging, or the like. By providing such services, a cloud platform may reduce the difficulty of developing mobile applications.
In at least one of the various embodiments, mobile application developers may access the services of a cloud platform by integrating their application with a cloud platform interface, such as cloud platform interface 322. In other embodiments, mobile application developers may integrate with the cloud platform services using other mechanisms, such as, web applications, web services, or the like. Also, while mobile application and mobile application developers are described, the innovations disclosed are not limited to mobile applications and/or mobile application developers. One of ordinary skill in the art will appreciate that other applications and/or application developers may be enabled to benefit from the innovations described herein.
In at least one of the various embodiments, a cloud platform may enable mobile application developers to generate application modules that include cloud code. The cloud code modules may be deployed to a cloud platform enabling additional/customized functionality for the applications to be executed on the cloud platform. In at least one of the various embodiments, mobile application developers may access the deployed cloud code in their mobile applications using specialize function calls through the cloud platform interface.
In at least one of the various embodiments, deployed cloud code may be activated on the cloud platform and may be associated with function calls, trigger points, or the like. In at least one of the various embodiments, the cloud code associated with function calls may be accessed by name from within a mobile application using a cloud platform interface. Likewise, cloud code associated with a trigger point may be executed before, during, or after, the occurrence one or more events and/or function calls that correspond to the trigger point.
In at least one of the various embodiments, the cloud platform and/or cloud platform interface may provide one or more API's that enable mobile application developers to create mobile applications that may access and/or execute deployed cloud code. For example, a mobile application developer may deploy cloud code that includes instructions that enable sending data to an external system such as, a bank. This cloud code may be deployed and associated with a function call named, for example, ‘update_bank_info’. If the cloud code is successfully deployed, the application developer may enable mobile applications to employ a function with the mobile application to execute the deployed cloud code on the cloud platform. In one embodiment, a function call command may look like “cloud_platform(‘update_bank_info’, ‘12345’, ‘100.00’, ‘deposit’, ‘Payday’);” In this example, ‘cloud_platform’ may be an application interface function provided by the cloud platform interface enabling access to the cloud platform; ‘update_bank_info’ identifies the specific cloud code that should be used (e.g., the deployed cloud code that is associated with the name ‘update_bank_info’); and the remainder of the terms may be input parameters that may be passed to the cloud code as it is executed on the cloud platform.
In at least one of the various embodiments, if a communication that includes a function call associate with cloud code is provided to the cloud platform, the cloud platform may validate, the cloud code call, locate the previously deployed cloud code, identify a suitable cloud code server, execute the cloud code using any supplied parameters, and provide the results to the requesting mobile application.
Many mobile development platforms may require developers to understand and develop expertise in writing software for several technology layers that may be common to mobile application development. For example, in most cases, a developer may need to have expertise with several technology layers, such as, user-interface frameworks (UI), mobile networking, server networking, application logic (mobile client and service-side), database operations, machine level (hardware and/or virtual), or the like. Some of this complexity may be mitigated by integrating with generalized cloud based services that may provide access to virtualized databases and virtualized server resources, but much of the application development complexity still remains the responsibility of the developers.
In at least one of the various embodiments, a software development kit and/or an API provided by the cloud code platform (e.g., via cloud platform interface 322) may reduce the number of technology layers required for development mobile applications. By utilizing the cloud platform developers may reduce required technology layers to the UI application layer and the cloud platform interface 322. Developers may rely on the cloud platform and/or the cloud platform interface to perform the complex actions that are normally done by other technology layers, such as, mobile networking, server, networking, application logic (mobile client and service-side), database operations, and machine level (hardware and/or virtual), or the like.
Furthermore, in at least one of the various embodiments, the cloud code produced and deployed to the cloud platform by mobile developers may also use the cloud platform interface (e.g., the cloud platform API, SDK) from within the cloud platform itself. Thus, in at least one of the various embodiments, the mobile application developers may leverage their expertise in using the cloud platform interface for developing server-side cloud code deployed for running on the cloud platform.

Developer client device 506 may enable mobile application developers to generate cloud code and deploy it to cloud platforms. In at least one of the various embodiments, developer client device 506 may be one of a, client device 120, client device 122, client device 124, network device 400, or the like.
In at least one of the various embodiments, cloud platform server 504, may be a network device arranged to communicate with consumer client device 502 and developer client device 506 over a network. In at least one of the various embodiments, cloud platform server 504 may be operating on cloud platform server device 114, enclosure of blade servers 110, enclosure of server computers 116, blade server 250, network device 400, or the like, or combination thereof. In at least one of the various embodiments, the cloud platform server may operate as the main access point for the cloud platform.
In at least one of the various embodiments, if cloud platform server 504 is provided cloud code from a developer client device (e.g., such as developer client device 506) it may perform a variety of validation operations. If the cloud code is validated may be deployed and activated.
In at least one of the various embodiments, if a command for executing cloud code (e.g., a particular function call) is provided to cloud platform server 504, cloud platform server 504 may locate the appropriate cloud code and determine one or more cloud code servers, such as, cloud code server 508 or cloud code server 510 where the actions enabled by the cloud code may be performed.
In at least one of the various embodiments, cloud code server 508, and cloud code server 510, may be devices, such as, cloud code server device 112, enclosure of blade servers 110, enclosure of server computers 116, blade server 250, network device 400, or the like, or combination thereof. In at least one of the various embodiments, cloud code servers may include, applications such as, cloud code application 282, or cloud code application 422. In at least one of the various embodiments, cloud code server 508 and 510 may communicate to cloud platform server 504 using network 516.
In at least one of the various embodiments, there may be a plurality of cloud code servers arranged into cooperative clusters, each accessible over a network (e.g., network 516) by one or more cloud platform servers. In at least one of the various embodiments, cloud code servers may be operative on network devices separate from the cloud platform servers, or in some embodiments the cloud code servers and cloud platform servers may be operative on the same network device.
In at least one of the various embodiments, cloud code servers, such as, cloud code server 508 and cloud code server 510 may be arranged to include one or more sandboxes, such as, sandbox 512 and sandbox 514 each which may be arranged to execute cloud code.
In at least one of the various embodiments, sandboxes may be computer processes enabled to provide isolating computing environments for executing cloud code. In at least one of the various embodiments, sandboxes, such as, sandbox 512 and sandbox 514, may be arranged to guard against the harm that a malicious, unsafe, or poorly engineered selection of cloud code may cause to the larger system and/or other sandboxes. Also, sandboxes may be used to help ensure that cloud code is prevented from accessing data and/or resources without authorization.
In at least one of the various embodiments, if a cloud code server is provided cloud code, it may determine a sandbox to use for executing the provided cloud code. In at least one of the various embodiments, if there are idle sandboxes, they may be retrieved from one or more queues or pools that contain/reference sandboxes that are standing-by ready to execute cloud code. In the case that an instantiated sandbox may be unavailable, the cloud code server may instantiate a new sandbox for executing the cloud code. In at least one of the various embodiments, if the execution of the cloud code is complete, the sandbox may be returned the queue.
In at least one of the various embodiments, the cloud platform may be arranged to establish a one or more timeout values, that if exceeded cancels and/or aborts the cloud code function call. In at least one of the various embodiments, each level of operation of the cloud code function call may have a defined timeout. In at least one of the various embodiments, the timeouts may be nested, in the sense that a first overall timeout is set as each function call associated with cloud code is provided to the cloud platform. Then secondary timeouts may be set for each stage of the process. The secondary timeouts may be shorter than the first timeout and shorter than any enclosing prior secondary timeouts. For example, the first timeout may be set to seven seconds, meaning that if the function call does not complete in seven seconds it may be canceled by the cloud platform (enabling the caller to retry). Also, a secondary timeout of four seconds may be set at the cloud code server stage of the process. Thus, if the cloud code server stage does not complete within four seconds the cloud code server may cancel the operation and report the timeout to the cloud platform. Further, a secondary timeout of two seconds may be set at the sandbox level. If the sandbox timeout is exceeded the sandbox may abort the execution of the cloud code and report the timeout and any associated error codes to the cloud code server. In at least one of the various embodiments, if there is time remaining at a “higher” level, it may be used to attempt to cure the cause of the timeout below.
In at least one of the various embodiments, watcher 518 may monitor the activity and operating characteristics of one or more sandboxes (e.g., sandboxes 512, 514, or the like, one or more cloud code servers (e.g., cloud code server 508, cloud code server 510, or the like), and one or more cloud platform servers (e.g., cloud platform server 504). Watcher 518 may be operative on any computing device, such as blade server 250, network device 400, or the like, that may be enabled to run watcher application 286, watcher application 426, or the like. Further, in at least one of the various embodiments, watchers and/or the watcher application may be operative on a cloud platform server such as cloud platform server 504 rather than being on a computing device that is separate from a cloud platform server.
In at least one of the various embodiments, servers that may be monitored by the watcher may establish communication with the watcher and periodically provide messages that indicate their operational status (e.g., heartbeat message). In at least one of the various embodiments, cloud code servers may update the watcher to indicate the status of the sandboxes as well as status of the cloud code server.
In at least one of the various embodiments, status messages regarding servers such as cloud code server 508, cloud code server 510, cloud platform server 504, may include various performance metrics, such as, CPU utilization, resident memory utilization, disk paging, network throughput, or the like. In at least one of the various embodiments, status messages regarding cloud code servers may also include, metrics such as, the number of sandboxes and their status (e.g., idle, busy, error), number of cloud code transactions, or the like.
In at least one of the various embodiments, watcher 518 may be arranged to monitor sandboxes which may enable the detection of dead/frozen sandboxes, run-away sandboxes, or the like.
In at least one of the various embodiments, if watcher 518 is provided status messages that indicate one or more problems may be occurring on a cloud code server, it may initiate one or more remedial actions. Remedial actions include, resetting a sandbox, killing and deleting a sandbox process, reallocating resources, adjusting resource quotas, rebooting a cloud code server, isolating a cloud code server from the cloud platform, or the like.
Furthermore, in at least one of the various embodiments, cloud platform server 504, cloud code servers 508-510, or watcher server 518 may be operative in a cloud-based computing environment. In at least one of the various embodiments, the platform may be deployed using virtual machines and/or virtual servers that may be managed in a cloud-based based computing environment.

In at least one of the various embodiments, if the privileges may be insufficient and/or incorrect, further action may be taken, including, requesting that additional credentialing information be provided, rejecting the provided cloud code, logging the authentication failure, or the like, or combination thereof.
Next, at block 706, the provided cloud code may be scanned to detect if it may include unsafe source code that may be recognized as having one or more undesirable and/or unsafe characteristics, such as, the potential to cause performance problems, attempts to access reserved resources, use of reserved words, attempted access of unauthorized software/system libraries, or the like.
In at least one of the various embodiments, one or more techniques may be employed to validate the provided cloud code. In at least one of the various embodiments, more or less techniques may be used depending defined policies that may be based on configuration values, or other sources.
In at least one of the various embodiments, the cloud code may be scanned to identify code patterns that may indicate unsafe behavior, such as, unbounded recursion, infinite loops, excessive memory allocation, or the like. Unsafe code is not limited to the deliberate attempts to disrupt the cloud platform; mobile application developers may unwittingly introduce cloud code that includes unsafe code.
In at least one of the various embodiments, the cloud code module contents may be examined to see if the number of network access system calls exceeded a define threshold. The threshold value may be defined using configuration values, or the like.
In at least one of the various embodiments, additional tests may include estimating the probability that the function call will timeout before completion.

If provided cloud code includes one or more of the recognized patterns it may be deemed unsafe.
In at least one of the various embodiments, various techniques such as pattern matching, heuristics, or the like, may be employed to identify unsafe code. In at least one of the various embodiments, a cloud platform application may parse the provided cloud code to identify loops that have the potential to be unbounded. For example, a loop that is bounded by the value of a passed in parameter may be determined unsafe if the value of the passed in from client application has the potential to very large. Likewise, cloud code that includes recursion that has the potential for unbounded (or near unbounded) recursion depth may also be determined to be unsafe.
In at least one of the various embodiments, cloud code that makes network calls to the cloud platform may also be determined to be unsafe based on its potential for consuming the resources of many sandboxes if many and/or recursive cloud platform-to-cloud platform network calls are made.
In at least one of the various embodiments, particular system/library calls inherent in the programming language used write the provided cloud code (or its runtime environment) may be deemed unsafe if they are included in the cloud code. For example, a cloud platform may be configured to prevent local resources, such as files, from being accessed from within a sandbox, thus if the provided cloud code includes functions for accessing protected local resources, even though the files access call are standard to the cloud code's programming language, that cloud code may be determined to be unsafe.
In at least one of the various embodiments, the provided cloud code may be compiled by a compatible compiler. Errors detected during compile time may be considered during the validation of the provide cloud code.
Next, at block 708, the cloud platform may perform one or more actions to repair unsafe provided cloud code.

In at least one of the various embodiments, for a given unsafe condition, policies may be set to reject the provided cloud code and report that the cloud code is invalid, and optionally supply the reason to the mobile application developer.
In at least one of the various embodiments, the portions of the unsafe provided cloud code may be replaced by safe code. In at least one of the various embodiments, fail safe conditions may be inserted into loops and recursions that have to potential to be unbounded. For example, the cloud platform may insert a test inside a loop to establish a predefined upper bound.
In at least one of the various embodiments, sandboxes designed to execute the cloud code may include one or more runtime engines and/or compilers for compiling the provided cloud code and/or executing it. These runtime engines and/or compliers may be compatible with the programming language comprising the cloud code. In at least one of the various embodiments, they may include modifications that enable the cloud platform to add failsafe/safety code to the cloud code during compilation/execution. Thus, in at least one of the various embodiments, the cloud platform compilers may insert object code that guards against run-away loops, unbounded recursion, excessive memory allocations, or the like.
Further, in at least one of the various embodiments, the runtime engines/compilers may be arranged to silently override standard operations normally available in a runtime engine and/or in a programming language. Additional safety precautions may be included in the overridden functions to enable otherwise unsafe cloud code to be safer.
In at least one of the various embodiments, if a computer language used by provided cloud code enables unbounded (unsafe) memory allocation, the implementation of the cloud platform runtime-engine/compiler may be modified to include built-in memory allocation limits.
Likewise, in at least one of the various embodiments, if a cloud code computer language enables memory buffers to be overwritten, the cloud platform runtime-engine/compile may be modified to guard against over writing buffers.
In at least one of the various embodiments, the cloud platform may enable users with sufficient permissions and/or authority to over ride one or more determinations that the cloud code is unsafe. This enables users to review the source code of cloud code and override the cloud platform validation process as necessary.
At decision block 710, if the provided cloud code is determined to be safe, control may flow to block 714. Otherwise, in at least one of the various embodiments, control may flow to block 712.
At block 712, because the cloud code remains unsafe it may be rejected and the user attempting to deploy the cloud code may be notified of the rejection. Next, control may be returned to a calling process.
In at least one of the various embodiments, a record may be kept of the why the cloud code was determined to unsafe and which application developer provided the cloud code. In at least one of the various embodiments, if mobile application developers provide unsafe cloud code a number of time that exceed a defined threshold, those mobile application developers may temporarily or permanently barred from the cloud platform.
At block 714, if the actions performed in block 708 have resolved the issues (if any) that made the cloud code unsafe, the provided cloud code may be registered and activated for execution and control may be returned to a calling process.
