Solution Design in WebSphere Process Server and WebSphere ESB: Part 2

Part 1 of this series described how Service-Oriented Architectures (SOAs) mature through a number of stages, and showed what solution styles are used at each level. This paper focuses on the advancements made moving from Enterprise Application Integration (EAI) to Service Exposition, in other words from Service Integration Maturity Model (SIMM) level 3 to 4. This paper will discuss what it means to expose a mature service on an Enterprise Service Bus (ESB), and look at the features one might use from WebSphere Process Server (hereafter called Process Server) or WebSphere Enterprise Service Bus (WESB).
