Abstract: One or more examples provide a method of performing a REST API operation at a server computing system includes receiving a request of a hypertext transfer protocol (HTTP) session from a client computing system. The request includes data for requesting performance of the REST API operation and issuance of progress updates. The method further includes sending a first part of a response of the HTTP session to the client computing system. The first part of the response acknowledges the request. The method further includes sending, while the REST API operation is performed, at least one additional part of the response to the client computing system, each additional part of the response having a progress update for the REST API operation. The method further includes sending, upon completion of the REST API operation, a final part of the response to the client computing system having a result of the REST API operation.

Abstract: The current document is directed to an interface and authorization service that allows users of a cloud-director management subsystem of distributed, multi-tenant, virtual data centers to extend the services and functionalities provided by the cloud-director management subsystem. A cloud application programming interface (“API”) entrypoint represents a request/response RESTful interface to services and functionalities provided by the cloud-director management subsystem as well as to service extensions provided by users. The cloud API entrypoint includes a service-extension interface and an authorization-service management interface. The cloud-director management subsystem provides the authorization service to service extensions that allow the service extensions to obtain, from the authorization service, an indication of whether or not a request directed to the service extension through the cloud API entrypoint is authorized.
