In one embodiment, a computer system receives registration information for available services provided by a service provider. The registration information includes information identifying functionality provided by the available services, and the registration information is used to register the available services with the intermediary service. The computer system receives a service request from a client computer system identifying a function that is to be performed by at least one of the available services registered at the intermediary service. The computer system determines which of the registered available services is configured to provide the functionality requested by the client and processes the received service request using various system functionality components, so that the service request is configured for service-specific processing provided by a registered available service. The computer system also sends the processed service request to the registered service determined to be configured to provide the functionality requested by the client.
