It has come to my attention that there are really two kinds of SOA technology vendors out there, old school and new school - each offering very different approaches to solving the SOA problem. I'm not going to mention any particular vendors, but you guys can guess who they are.
Keep in mind, what's important here is that not any particular approach or technology is correct, but that the approaches and technologies you employ match up with your requirements and business expectations. However, it's also important to understand exactly the type of technology you're going to leverage, including its core - that's the point I'm attempting to make here.
Old-School SOA Vendors
Old-school SOA vendors are those with "legacy" integration or application development solutions that "SOA-tized" their stuff, basically adding Web services interfaces, orchestration, governance, etc...
