Enterprise application session control and monitoring in a large distributed environment

Mechanisms are provided for performing centralized control of application sessions across a distributed computing environment comprising a plurality of application servers. A request to perform an application session control operation to control the application sessions associated with a specified user account identifier across the plurality of application servers in the distributed computing environment is received. A plurality of application instances upon which to perform the requested application session control operation are identified. An application session control request is transmitted to a plurality of session control clients associated with the application instances on the plurality of application servers of the distributed computing environment. The application session control request causes each session control client to control a user's ability to use the application sessions of application instances, associated with the session control client, that are associated with the specified user account identifier, to access the associated application instances.
