Patent Application
20130117749
Cloud computing provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. Parallels to this concept can be drawn with the electricity grid, wherein end-users consume power without needing to understand the component devices or infrastructure required to provide the service.
Cloud computing describes a new supplement, consumption, and delivery model for IT services based on Internet protocols, and it typically involves provisioning of dynamically scalable and often virtualized resources. It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet. This may take the form of web-based tools or applications that users can access and use through a web browser as if the programs were installed locally on their own computers.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter. Nor is this Summary intended to be used to limit the claimed subject matter's scope.
Platform management may be provided. First, a package may be received. The received package may then be separated into a plurality of deployment groups. Next, a plurality of tasks may be created for deploying the plurality of deployment groups. Then the plurality of tasks may be executed.
Both the foregoing general description and the following detailed description provide examples and are explanatory only. Accordingly, the foregoing general description and the following detailed description should not be considered to be restrictive. Further, features or variations may be provided in addition to those set forth herein. For example, embodiments may be directed to various feature combinations and sub-combinations described in the detailed description.
The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate various embodiments of the present invention. In the drawings:
The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar elements. While embodiments of the invention may be described, modifications, adaptations, and other implementations are possible. For example, substitutions, additions, or modifications may be made to the elements illustrated in the drawings, and the methods described herein may be modified by substituting, reordering, or adding stages to the disclosed methods. Accordingly, the following detailed description does not limit the invention. Instead, the proper scope of the invention is defined by the appended claims.
An application platform (e.g. The Windows® Azure® platform) in cloud 105 may allow datacenters to host and run applications. The application platform may serve as a runtime for applications and may provide a collection of services that may allow development, management, and hosting of applications off-premises for end users of the plurality of computing devices. Most of the applications may use more than one of these services to function. Also, components deployed to these services may need to be able to communicate and versioned as a unit. Conventional systems may not guarantee consistency across all services for a given application. Consequently, embodiments of the invention may provide a system that may provide distributed, resilient, and transactional deployment, upgrade and removal of applications across the application platform's services.
Embodiments of the invention may provide a packaging format, a set of lifecycle application program interfaces (APIs), a data store for storing deployment metadata, and application packages. In addition, embodiments of the invention may provide a set of components called deployment groups that may implement lifecycle operations for specific targets.
The packaging format may describe the application to be deployed at a high level as well its components and their relationships to each other. In a first phase of a deployment process, for each component in the package, an appropriate set of containers may be provisioned by a deployment group through APIs that may be specific to a deployment target (e.g. a database provisioned through SQL management interfaces). Subsequently, application components may be deployed to the containers. If all deployment steps were successful in the first phase, a second phase may configure any connections between the components.
The aforementioned process may be resilient to data center server crashes, connectivity issues, or errors in individual component deployments. For example, if a component deployment fails, it may be rolled back and retried. If retries are exhausted, then the whole app deployment may be rolled back. If server crashes or network connectivity is restored, a scheduled deployment job may pick up where previous processing left off. This is because the state of a deployment may be persisted in the store. An engine executing the deployment may make intelligent decisions about which components to rollback, retry, or install for the first time. Accordingly, embodiments of the invention may provide full multi-tier application deployments by the end users without system administration intervention.
Moreover, the engine executing the deployment may also support upgrading applications in a reliable way. This upgrade process may make a copy of a database, if it exists, and the site including the data stored in lists and document libraries. The copies may then be upgraded in place. If the upgrade process fails, the upgrade process may fall back to the original application instance.
Method 200 may begin at starting block 205 and proceed to stage 210 where computing device 500 may receive a package 305. For example, a developer may wish to create an application (e.g. an interview management application) that may have three components. A first component may comprise a database that stores data about interviewees and how the interviews go. A second component may comprise code that the developer may write to processes the data and create reports. A third component may comprise a visual layer that may display the data and reports and interact with users (e.g. over the internet). The aforementioned interview management application is an example and any type of application may be used.
In writing the aforementioned interview management application, the developer may aggregate the three components into package 305. Accordingly, package 305 may comprise a plurality of parts corresponding to the aforementioned components. For example, the plurality of parts may comprise, but are not limited to, a first part 315 corresponding to the aforementioned code component (e.g. an ASP.Net web application), a second part 320 corresponding to configuration of the interview management application, a third part 325 corresponding to the aforementioned database component (e.g. SQL DDL scripts that define the schema of the database that the application needs), and a fourth part 330 corresponding to the aforementioned visual layer (e.g. information display UR layer) component. Furthermore, package 305 may include a manifest 310 that may define a structure of package 305 and relationships between the plurality of parts. After the developer aggregates the three components into package 305 as illustrated in
From stage 210, where computing device 500 receives package 305, method 200 may advance to stage 220 where computing device 500 may separate received package 305 into a plurality of deployment groups 405 as illustrated in
Consistent with embodiments of the invention, computing device 500 may open received package 305, examine its contents, and separate the plurality of parts into plurality of deployment groups 405. For example, computing device 500 may separate first part 315 corresponding to the aforementioned code component and second part 320 corresponding to configuration of the interview management application into code deployment group 410. In addition, computing device 500 may separate database part 325 into database deployment group 415. Furthermore, computing device 500 may separate information display part 330 into visual layer deployment group 420.
Embodiments of the invention may have more or less that the above mentioned three deployment groups 405. For example, it is possible that the interview management application may not include a database and/or a visual layer. Consequently, the plurality of parts may not respectively include third part 325 corresponding to the aforementioned database component and/or fourth part 330 corresponding to the aforementioned visual layer component. Accordingly, plurality of deployment groups 405 may not respectively include database development group 415 and/or visual layer development group 420.
Once computing device 500 separates the received package into the plurality of deployment groups in stage 220, method 200 may continue to stage 230 where computing device 500 may create a plurality of tasks for deploying plurality of deployment groups 405. For example, computing device 500 may create a series of tasks (e.g. a job) and save them to a content database. In order to determine what tasks to include in the content database, computing device 500 may analyze plurality of deployment groups 405 and determine what different tasks to include. In other words, the content database includes a series of tasks queued. These tasks may have dependencies between one another where the queue may be ordered so as to execute tasks that may need to go first before any subsequent tasks. For example, a task may execute a “fix-up” stage that may cause ones of the plurality of these deployment groups 405 to exchange information such as a database connection string.
After computing device 500 creates the plurality of tasks for deploying the plurality of deployment groups in stage 230, method 200 may proceed to stage 240 where computing device 500 may execute the plurality of tasks. For example, a timer process may run on computing device 500. The timer process may periodically check the content database for new tasks. When the timer process sees new tasks in the content database, the timer process may pull one task out at a time, executes it, and when successfully executed, the time process writes back to the content database that the task was finished. In this way, the status of tasks and their progress is persisted in a durable store.
When executing tasks, a number of failure issues may arise. For example, computing device 500 may go down during execution of the new tasks in the content database, but before all the new tasks in the content database are completed. However, the next time the job containing the tasks runs after computing device 500 is back up, since all the task definitions may be persisted to the content database, the job may pick up and resume from where it left off.
Another failure may arise due to network issues in cloud 105 that may cause deployment group implementation to stop responding to computing device 500. Consequently, embodiments of the invention may include a “rollback” feature. With the rollback feature, if one of the tasks in the job does not report back as successfully executed, then all the previous tasks in the job may be undone (i.e. rolled back.) If any of the undoing of the previous tasks does not report back as successfully executed, then the unsuccessful undo will be repeated until it is successful. Once all tasks are undone, computing device 500 may try to re-execute the tasks until all the tasks are successfully completed.
Embodiments of the invention may also include an update feature. For example, a first version of package 305 may be successfully deployed. Then, the developer may write a new, updated (e.g. second) version of package 305 and may want it to be deployed in place of the former, first version of package 305. In this case, manifest 310 of the second version of package 305 may indicate that it is a “Version 2.” Consequently, computing device 500 may compare the first version of package 305 to the second version of package 305 to determine what is different and then carry out a deployment (create and execute tasks) to replace the differences. For example, the second version may have a different database part that the first version. Consequently, the second version database part may be deployed in the place of the first version database part. Or the second version may not even use a database at all. In this case, the database part of the first version may be removed. Furthermore, the second version may have a different code part that the first version. Consequently, the second version code part may be compared to the already deployed the first version code part. Accordingly, the difference between the two code parts may be deployed. Information display part 330 in the first version may be completely different in the second version, so display part 330 may be completely replace in the second version deployment. Also, package 305 for the second version may have parts not corresponding to any parts of package 305 for the first version. In this case, parts in package 305 for the second version not corresponding to any parts of package 305 for the first version may be deployed.
Further regarding the update feature, if the update process identifies that a component is present in both the old and the new version, it may update the component in a manner that avoids the possibility of data loss and may maintain end user access to the application while the update is being carried out. This may be achieved by the deployment group contract for a computation container affording the following characteristics: i) a way by which a component may be backed up; ii) a way by which the backed up component may be updated; iii) a way by which the current component and the updated, backed up component may be switched from an end user's perspective, quickly; and iv) a way by which all component switches can be synchronized such that any application availability loss perceived by the user is minimized.
In sum, a developer may create package 305 with a number of different parts. The developer may send package 305 to computing device 500 that may analyzes package 305 and create deployment groups 405. Computing device 500 may then analyze deployment groups 405 and write all of the tasks that are needed into the content database. A timer service may then pick up the tasks and execute the tasks based on their dependencies thus deploying package 305. Once computing device 500 executes the plurality of tasks in stage 240, method 200 may then end at stage 250.

Furthermore, the processing unit may be operative to execute a first portion of the plurality of tasks, to undo the executed first portion of the plurality of tasks, and to execute the plurality of tasks.
Yet another embodiment consistent with the invention may comprise a system for providing platform management. The system may comprise a memory storage and a processing unit coupled to the memory storage. The processing unit may be operative to receive a first package corresponding to a first version of software, separate the received first package into a first plurality of deployment groups, and to create a first plurality of tasks for deploying the first plurality of deployment groups. Furthermore, the processing unit may be operative to execute the first plurality of tasks, receive a second package corresponding to a second version of the software, and to undo, in response to receiving the second package corresponding to the second version of the software, the deployment of the first plurality of deployment groups. Moreover, the processing unit may be operative to separate the received second package into a second plurality of deployment groups, create a second plurality of tasks for deploying the second plurality of deployment groups, and to execute the second plurality of tasks.
