Resource access control in cloud environments

Access control management to shared resources in a common resource directory between different users of cloud data centers can be implemented as computer-readable methods, media and systems. A resource managing service receives a request to access resources of a resource directory managed by the resource managing service. The request includes a token for identity authentication. The resource managing service determined a container membership associated with the token, where the container membership is associated with a container from a set of containers for the resource directory. The container includes one or more resources in a tree data structure of the resource directory. The resource managing service filters access rights defined in authorization primitives associated with the container membership based on container policy rules for the set of containers in the resource directory. The resource managing service provides access to a set of resources from the resource directory.
