Control of usage of computing services based on dynamic grouping

A solution is proposed for controlling usage of computing services. A corresponding method comprises allocating a new usage token to a user in response to a usage entitlement thereof being insufficient to meet a usage weight of a new computing service. The usage entitlement is updated according to the new usage token and the usage weight of the new computing service, and the usage of the new computing service is enabled in response thereto. A computer program and a computer program product for performing the method are also proposed. Moreover, a system for implementing the method is proposed.
