Capturing and deploying applications using maximal and minimal sets
Systems and methods are described for packaging and deploying applications using minimal and maximal component sets. A minimal set of application components that includes at least the necessary components for launching the application is first downloaded to an endpoint device from a central server. The application is launched on the endpoint from the minimal set. If the application requests a missing component that is not available on the endpoint, the missing component is requested and delivered on-demand from a maximal set located on the server, where the maximal set contains all possible application components. The application is suspended during the download of the missing component. After the missing component is downloaded, the application is resumed, having access to the missing component on the endpoint.

locating the missing application component in a maximal set, the maximal set comprising application components not available in the minimal set;
conveying the located missing application component in the maximal set to the requesting one or more client devices; and
in response to receiving at the management server a predetermined threshold number of requests for the missing application component from client devices executing the application from the minimal set, modifying the minimal set stored on the management server by adding the missing application component to the minimal set.

conveying a manifest identifying components in the maximal set to the plurality of client devices.
6. The method of claim 5 , further comprising:
determining, at the requesting client devices, whether the missing application component is available in the maximal set based on the manifest.

locating the missing application component in a maximal set, the maximal set comprising application components not available in the minimal set;
conveying the located missing application component in the maximal set to the requesting one or more client device; and
in response to receiving at the management server a predetermined threshold number of requests for the missing application component from client devices executing the application from the minimal set, modifying the minimal set stored on the management server by adding the missing application component to the minimal set.
9. The computing device of claim 8 , wherein the memory further includes instructions that when executed by the at least one processor, cause the computing device to perform the steps of:
during execution of the application from the minimal set on the plurality of client devices, detecting, at the requesting client devices, an access by the application to the missing application component;
suspending execution of the application on the requesting client devices; and
sending the request for the missing application component from the requesting client devices to the management server.
10. The computing device of claim 8 , wherein the maximal set is created by capturing disk content from a computing device on which the application is installed, according to a predefined policy.
11. The computing device of claim 10 , wherein the predefined policy instructs at least one of: to capture all content on the computing device, or to capture all content on the computing device except content in predefined excluded areas that are deemed irrelevant to execution of the application.
12. The computing device of claim 8 , wherein the memory further includes instructions that when executed by the at least one processor, cause the computing device to perform the steps of:
conveying a manifest identifying components in the maximal set to the plurality of client devices.
13. The computing device of claim 12 , wherein the memory further includes instructions that when executed by the at least one processor, cause the computing device to perform the steps of:

14. The computing device of claim 10 , wherein the predefined policy instructs to capture content on the computing device in all memory locations deemed to be possible locations of application components.
15. A non-transitory computer readable storage medium comprising one or more sequences of instructions, the instructions when executed by one or more processors causing the one or more processors to execute the operations of:
