| Abstract: |
A convergent approach to SOA, EDA and CEP
In previous reports we have provided guidance on modeling events in context with the business process and services and shown how the business event is an integral part of the service architecture. We have also recommended that events are key triggers for business intelligence systems. In this report we provide some methodological guidance on appropriate integration of Event Driven Architecture and Complex Event Processing tools and platform capabilities into the service architecture.

| Backgrounder: |
Analysts and vendors have been talking about the potential synergy between Service Oriented Architecture (SOA) and Event-Driven Architecture (EDA) for many years. In May 2003, Gartner claimed that EDA was “poised for wide adoption”1.
And in a January 2008 interview, WebSphere CTO Jerry Cuomo said that event processing was “the next big thing in SOA”. Three weeks later, IBM announced it had acquired AptSoft, a software company specializing in event processing2 . IBM now prefers to use the term Business Event Processing.
In the meantime, there has been a lot of talk about the “on-demand business” or the “adaptive enterprise”. We can understand the responsiveness of an organization in terms of the range and variety of events it is capable of responding to, and we can understand the future strategy of an organization in terms of the events it wishes to be able to respond to.
Some vendors would like us to believe that Event Processing is an entirely new paradigm, necessitating the purchase of a pile of extra technology and consultancy. Other vendors present Event Processing as a style of SOA that is largely (although not entirely) supported by existing SOA platforms, and remind us of the origins of ESB in message-oriented middleware.
