The Service Management and Control (SMC) Policy Enforcement Services provide functions to enforce technical and business policies related to performance, quality of service, agreed service levels, and ensures compliance with business and legal rules. The services enforce policies on services hosted within the Platform. Depending on implementation, these services can be standalone components in front of protected services (e.g. functioning like reverse proxy); or they can be part of the web hosting platform (e.g. a pipeline in an application server).
