When looking at technology buying patterns in the world of SOA, there's one common thread. The Global 2000, and many government agencies, are purchasing from their existing vendors, no matter what the needs or requirements. I call these solutions purchasing "comfort technologies" since they consider the relationship with the vendor more than the value of the technology itself. It's comforting to deal with the same company, people, and platform. Moreover, many of these same companies working with "comfort technologies" are also allowing the vendors to design and define their solution. I call these vendor-driven architectures or VDAs but they are always called a bad idea if you understand the core issues. What's most disturbing is that this seems to be an emerging buying pattern. Architects are making the "SOA deal" with a vendor in hopes some magical technology emerge... (more)

"Many SOA Vendors Can't Explain Their Own Product," Claims David Linthicum

Last month I wrote about vendor-driven architectures (VDA), and I had a few vendors ask me to look on the other side of the fence. In essence, to consider how vendors can better address the needs of the customer, considering the new drivers with SOA.

Indeed, I'm taken aback weekly by a vendor pitch that just does not flatter their technology, perhaps even making them take a few steps back in my book, and perhaps in the opinions of their customers. Core to this is the fact... (more)

A few people who have been reading my blog and this column, and listening to my podcast, as well as reading other SOA blogs and articles, have become a bit confused pertaining to the notions of: SOA Reference Model(s) SOA Reference Architecture(s) And how all of this works and plays with Enterprise Architecture I spent a few hours of my weekend attempting to research and define these concepts a bit better, in essence, taking everyone's opinions and normalizing them so they make better sense. What I found were many of the same notions, defined differently, but all attempting to s... (more)

Why 'Enterprise Architects' Are Ineffective with SOA

Architectures are like archaeology; in essence, layers upon layers of systems, applications, databases, and connections, typically built or procured to solve a tactical problem. Many corporations talk a good game and brag about the strategic long-term direction of the enterprise architecture that serves the business. The fact is, tactical needs have trumped strategic direction over the years. Thus, layers upon layers of technology on top of technology are the end result, and an architecture that is inflexible, static, fragile, and thus difficult to change along with the business...
