All good points. SOA is most definitely about architecture. While I wouldn't say "SOA is integration" per se, I'd say that integration is one of the core values of the SO approach. Services have 1 or more interfaces. Interaction with services is via those (and only those) interfaces. Services (and other components such as service clients) exist in independent ownership domains. Those characteristics are the heart of integration. SO demands that one consider integration up front rather than as an afterthought.
IMO, integration strategy is a side-effect of applying SO principles at the enterprise level. Side note: Redundancy isn't always bad and eliminating it isn't always the right course of action. Generally speaking, eliminating redundancy is good but we must be careful about blindly following that principle. -Rob --- In [email protected], "Anne Thomas Manes" <atma...@...> wrote: > > While I agree with the last line, I disagree with the leading one: > "SOA is integration".
