SOA Initiatives Find Warming Climates
Opinion: Proven with other technologies, service-oriented architectures gain Web services leverage to transform enterprise IT.In the current issue of eWEEK, I report on a conversation that I moderated late last month among players on the field of service-oriented architecture (SOA). The group included representatives from several vendors of SOA technologies and services, plus an enterprise IT buyer to keep those vendors focused on reality. It seemed to me that there were two key points to the discussion:
- The use of Web services technology does not inherently lead to the creation of a service-oriented environment. This point, made by several participants, bore out an argument that I made last fall: that brittle, slow and costly systems can be built with any technology.
- On the other hand, many enterprises are seeing significant financial returns from SOA-based initiatives, often begun with earlier generations of technology and architected to include but not depend on emerging Web services implementations. Such efforts are now becoming easier to undertake and expand because of the low barriers to entry that Web services tools can provide.
The resulting climate encourages three results.
- SOA construction is increasingly being driven by financial rather than technical imperatives, resulting in broader and more vigorous management support for the direct and indirect costs of such a transformation.
- Web services adopters are less inclined to walk around the technology seeking excuses -- such as gaps in multivendor standards -- to postpone trying it out. Theyre more likely to see the standards glass as nine-tenths full rather than one-tenth empty, and to build what they can with what they have today.
- The advent of a genuine services platform in an organization paves the way for a service-based organization that has the leverage to break down silos of data and code and start building more efficient and strategic systems.
