US Patent 10063601 Client identification for enforcing computer resource quotas

A system, method, and apparatus are provided for identifying clients or consumers of one or more controlled resources within a computing environment (e.g., a data center, a computing cluster). The resources may be controlled via the enforcement of quotas, wherein different clients have different quotas for the controlled resource(s). A client associated with a given call to a resource is identified using a tuple formed from identifiers of multiple services in the call stack, such as a first service (e.g., a front-end or user-facing service) and an immediate service (e.g., a final service in the stack prior to receipt of the call at a gateway, broker, or other entity that manages access to the controlled resources).
