Application Provisioning Job submission, and indeed any sort of workload manager, implies the ability to discover, describe, provision and manage the lifetime of an appropriate application code onto an identified computing resource. In many instances, this can be done at a very high level, but some scenarios will require very specific descriptions at the application layer. This, in turn, may place requirements for a specific operating system and version, possibly implying a certain patch level and hardware requirements. EGA's Reference Model describes the overall flow of activity involved in provisioning a high-level component and decomposing the required work into accessible quanta: ACS and CDDLM are specific proposals/WGs that attack the problems of describing and managing the lifetime of specific applications.
