Toward a pattern language for Service-Oriented Architecture and. Introduction One way to explore the value of Service-Oriented Architecture (SOA) is from the perspective of the flexibility that is provided to the business and IT sides of the value equation. Business value is created when a set of recomposable business process elements are defined as the key capabilities of a business.
Then the business model that is created as a result of composing those business elements into processes can more effectively be supported by a flexible IT infrastructure with services that support those specific processs elements. Another way to look at flexibility is in terms of future extensibility. This is achieved by introducing a service layer into an enterprise architecture. Packaged applications and existing systems can be integrated through SOA by a loosely coupled set of service interfaces that collaborate to achieve business objectives. This flexibility of SOA is reminiscent of a pattern, namely, the Strategy pattern. Variation-Oriented Analysis and Design. Java Idioms.
