Abstract: Described herein are methods and systems for providing software development services according to an execution environment specified in the requests. For instance, instead of performing compilation on a stand-alone desktop computer, software development activities including, compilation are performed by a service provider in response to a general query from a client requester. Service provider avoids computing results each time a request is received by maintaining a cache of results. To ensure that stored results are compatible to results that can be obtained by re-computation, results are computed according to a specified execution environment. The execution environment for computing is first created on a virtual machine on which aspects of the environment such as a specific version of an operating system and software development tool are established. The execution environment is then saved and invoked on a virtual machine during computation of results for software development requests.

Abstract: Described herein is at least one implementation employing multiple self-describing software artifacts persisted on one or more computer-storage media of a software-based computer. In this implementation, each artifact is representative of at least part of the software components (e.g., load modules, processes, applications, and operating system components) of the computing system and each artifact is described by at least one associated “manifest,” which include metadata declarative descriptions of the associated artifact.
