Only a couple of years ago, people were still asking what the acronym SOA meant. Now, there's a whole new debate, but at a different level. According to open source SOA proponent Dave Rosenberg, some associate SOA with Web services, some with ESBs, and some with the giant stacks being offered by large vendors. His take: They're all SOA, and the point is that one size doesn't fit all.
An article in Insurance Networking News portrays SOA in an entirely different light, as a way to inexpensively leverage legacy applications.
And while various pundits argue about what SOA is now, others -- largely marketing types -- are starting to talk about SOA 2.0, a notion that well-known SOA guru David Linthicum finds "just plain silly."
And then there's the conservative camp that claims there's nothing new under the sun, and that includes SOA. After all, wasn't CORBA all about reuse and modular design?
Worst of all, nobody is quite sure how to pronounce it, with ess-oh-ay and so-uh both in contention.
