SOA as an Architecture Pattern

Service-Oriented Architecture (SOA) has become an ugly word in the industry. Not only is everyone more confused than ever about what SOA is, but the tooling and products surrounding SOA has made it into a ubiquitous buzzword that has little or no meaning these days. That said, SOA as an architecture pattern is still very much alive and solves many issues within a service-based architecture approach. So what is SOA from an architecture standpoint? In this product-free session we will take a detailed look at SOA from an architecture pattern point of view, understand how abstraction plays a part in SOA, and also understand the implementation aspects of the pattern. At the end of this session we will look at a few service bus considerations, including dealing with single point of failure scenarios, performance bottleneck issues, and service bus roles and responsibilities.

Agenda:

• architecture pattern elements
• forms of abstraction
• pattern implementation (no products!)
• service bus considerations
