James Governor writes about the Service Component Architecture here. He also linked to Neil Ward-Dutton's take.
He is, of course, right to be sceptical... a major announcement like this should be critically assessed and the the technology evaluated on how well it solves real problems... It's our job to both argue for its merits and, more importantly, demonstrate that our clients are achieving real value from using it. As an IBM Software Services consultant, my job falls primarily into the second bucket. I wish I could blog about some of the exciting projects I'm seeing right now.
From reading the press coverage, however, I see two misconceptions appear again and again.
Misconception 1) "It's just a spec". Not quite... WebSphere Process Server is built on SCA and is shipping today.
Misconception 2) "It's a new abstraction layer". Not quite... it is more than that. I tried to articulate what I mean here but I'm not convinced I've done a good job. This point is very important so I'll try again soon.
