SO at AA level is more modest in its goals

"I think you may be reading Anne's quoted statements out of context. Anne is stating a bunch of web services, built for a single application project..."

Perhaps. Joe quoted Anne: "?It was just a bunch of Web services. ? The service is only built for one application and it?s never going to be used again.?"

I wonder if, because the service was app-centric (SO at the AA level), that it was labelled dismissively as JBOWS because it wasn't SO at the EA level? Is this our fundamental disagreement, where Burton feels SOA is only an EA concept but I feel it can be applied at any level?

" built for a single application project, will most likely not result in a simpler portfolio and a rationalized application architecture. A silo project mentality using web services will result in cheaper integration. "

I don't disagree.

" A silo project mentality will not result in enough re-use and sharing to reach touted goals of flexibility, agility, and business transformation."

Applied at the application level, SO is not likely to achieve much "business transformation." Why would SO at the AA level have that as a goal?

Blind reuse and sharing can be counter to the goals of flexibility and agility--indeed, sharing is often a primary reason for inflexibility.

"The scope and level must match expectations promoted to stakeholders."

Here again, I don't disagree. SO applied to an application architecture has a different set of stakeholders and a different set of goals than SO applied to higher architectural levels.

"Specifically, our 'Application Rationalization' and 'Application Portfolio Management' reports detail application architecture best practices."

I can't review those as I'm not a Burton client, but the summaries look good. And those would be good for pursuing SOA in the large--transitioning from application-centric to SO across the enterprise. And this would go beyond the AA level, correct?

I do agree that SO at the AA level looks an awful lot like mere integration. Maybe cheaper. Maybe less efficient (per info in Joe's article). But it is still SOA--it just has more modest goals than SO applied to higher levels.
