Does SOA need Paradigm Shift??

The need for a paradigm shift for embracing SOA within an organization is a lingering question. Certainly, many architects feel the pain of the IT organization when getting them to think on a more service based approach. Some experts feel there is no need for the shift, just a need for adoption of the technology. As many may have experienced, even good technologies can fail when used in the wrong hands.

Although the concept is not new, there certainly needs to be an improvement or shift in thought processes for successful implementations. A good example is building web services (SOA is not just about web services) in a more point to point fashion. Having multiple versions of web services for the same interaction will lead to high TCO and maintenance headache. There is a definite need for governance to maintain the norm in any implementation. Therefore, there needs to be some shift in thought process at different levels of the IT organization.
