Methods, including service methods, articles of manufacture, systems, articles and programmable devices are provided for controlling versioning of a service. A programmable policy broker is configured to communicate with a service registry and a policy repository comprising different service levels of a service. A location lookup is centralized in the service registry for different versions of the service. A call for a service by a consumer is mediated by causing the policy broker to select and return a correct service level from the policy repository as a function of a requirement of the consumer, look up a proper version of the service in the service registry from the different versions as a function of the returned correct service level, and call the looked-up proper service from a location associated with the proper service in the service registry.
