Meeting usage of services in a environment

摘要

A solution for metering usage of services—for example, in a SOA Framework—is proposed. For this purpose, the submission of any invocation of a provider service by a consumer service is intercepted by a license manager; a corresponding request is then submitted to a dedicated licensing service, which returns an entitlement code when the consumer service is entitled to submit the service invocation. The service invocation is decorated with this entitlement code and actually submitted to the provider service. The (decorated) service invocation addressed to the provider service is likewise intercepted by another license manager; a request is then submitted to the licensing service for verifying the received entitlement code. The running of the provider service is then enabled only if the entitlement code is correct.
