EXPERT RESPONSE
You will see an increasing amount of vendors trying to distinguish themselves as SOA becomes more commonplace. In fact, the SOA marketplace is expected to become the most competitive ever. As part of this trend, vendors will continue to produce and extend product roadmaps that provide paths for realizing a variation of SOA that is more specific to their platform.
There is, however, a good deal of commonality - both functionally and conceptually - across primary SOA vendor platforms. By focusing on these common characteristics, organizations can design their implementation of SOA in alignment with an industry perspective that avoids restrictive ties to any one proprietary roadmap (which also establishes a healthy abstraction of the architecture from its implementation options).
