Abstract: A resource registry provides nondeterministic operation environment affording flexible access for resource execution and status monitoring on the cloud. The resource registry service provides generic resource management utilizing registration, updating, and unregistration by resource providers. A requester for an operation may register in the resource registry, an operation resource having parameters defined in metadata. The resource registry notifies a registered resource listener of this registration of the operation resource. The resource listener may then execute the operation according to parameters defined in the operation resource. The resource listener returns a response to the resource registry, concerning a result of execution of the operation. The resource registry updates this status in the metadata of the operation resource. The requester is then able to look up the operation resource's metadata to determine current status of the operation.

Abstract: An operation execution request is created by an operation requester at an operations service module. The operation execution request is stored by the operations service module. A polling message for the operation execution request is received. The polling message includes a name of an operation. A response including the operation execution request and corresponding operation data is returned. An execution service schedules internally the operation for execution. The execution service sends an acknowledgement message to acknowledge the operation execution request. The operation data and corresponding operation execution request is locked for execution by other execution services. The execution service executes the operation with the operation data and provides result of the operation execution. The operations service module updates status of the operation execution request. The updated status is provided to the operation requester upon polling for status of the operation execution request.
