Two colleagues here at ebizQ have weighed in on the most vexing issue in the SOA world these days: how does SOA mesh with mashups, SaaS, and all the other aspects of the Web 2.0 and Enterprise 2.0 wave.
Krissi Danielsson talks about the disconnect between SOA and SaaS, noting that many commentators get the two concepts confused.
Keith Harrison-Broninski talks about the intersection between SOA and Web 2.0, which can called to as "Enterprise Web 2.0." In the midst of this intersection is enterprise mashups, which will eventually point the way to business process-driven architectures.
The growing convergence between Enterprise 2.0 (which includes SaaS) is the SOA story of 2007, and likely the story of 2008 as well. SaaS presents an interesting opportunity for SOA proponents as well. Business decision makers who may be flummoxed about the meaning of SOA typically get "SaaS" pretty quickly. SaaS providers that build their services on SOA-based standards will find their solutions best interlock with customers. Plus, a good analogy for SOA is that it's SaaS, delivered internally.
