If you asked Anne Thomas Manes, “Do you believe that applications that are modular, distributable , discoverable (have interface metadata), swappable (interface is separate from the implementation), and shareable/reusable are ‘dead’? She probably say “No, those apps are very much alive, they are best practices.” But that’s Gartner’s definition of SOA, so she actually might agree with Gartner if she was using the same definition. She says ‘SOA is dead’ because she is thinking only about RPC-style SOA. In her book “Web Services: A Managers Guide” she speaks highly of SOA – but she implies that all SOA is RPC-style SOA. She doesn’t count REST-SOA, event-driven SOA or P2P SOA as “SOA” and her book doesn’t even mention these other styles of operation to the best of my recollection (I just re-skimmed her book and couldn’t find any mention of them, and they were not in the index either). But now, several years after she wrote the book, she has apparently lost faith in RPC-style SOA. In reality, most of us at Gartner would agree with Anne that the other (non-RPC) styles of SOA are on the ascendancy. We’re just saying it in a more measured manner. No one thinks we’re going back to some pre-SOA software engineering practices. I am pretty sure even Anne would actually with that (and toi be fair, she never said that).
