Service orientation is an architectural paradigm that employs four tenets: explicit boundaries, autonomous services, shared schemas/contracts not classes, and policy-based compatibility. The Microsoft platform provides tools like Windows Communication Foundation to build service-oriented systems that are interoperable, productive, and conform to standards. An enterprise service bus is a centralized message broker that enables brokered communication, intelligent routing, and transformation between services.
