Service-Oriented Architecture

Architecture for Boundaryless Information Flow™

Service-Oriented Architecture (SOA) is an architectural style that supports service-orientation — a way of thinking in terms of services, service-based development and the outcomes of services. It is particularly important to The Open Group because it can enable enterprises to achieve Boundaryless Information Flow™.

SOA provoked lively debate when it burst onto the scene in 2005. Its advocates said that SOA would replace traditional IT architecture. The traditionalists replied that SOA was not really new; just a rehash of old (but good) ideas about encapsulation and loose coupling.

There is some truth in both of these positions, but both are fundamentally inaccurate. Although SOA does include earlier architectural ideas, it is a distinct style which marks a major step forward. And, to obtain maximum benefit from SOA, an enterprise needs traditional architectural disciplines and methods.

SOA is now established as a mature architectural style. Its deployment in enterprises is growing, and will continue to gain wider adoption. The advent of Cloud Computing is reinforcing the value of SOA, as SOA facilitates the effective use of the Cloud.

The Open Group SOA Work Group is working to assist business and information technology professionals within and outside of The Open Group to understand and adopt SOA. Its output is available from The Open Group Bookstore and on the Web in the SOA Source Book.
