Stew Welbourne: Yet more circular debate about whether SOA is just hype or whether it offers anything of value. It's addictive reading, not that I expect anyone to reach a definitive answer, but moreso to observe the correlation between the debating individual, the scope of his/her problem-space, and his/her corresponding position on whether SOA is hype or not. The relationship between Enterprise Architecture and SOA (and here I have just detatched a seprate thread about EA and Hype!!) is significant in my opinion as a result of the hugely important question of scope. The good old example of the difference between an Enterprise Architect and a System or Application Architect is the analogy with Town Planners and Building Planners. In simple terms Enterprise Architects are focusing at the optimal arrangement of buildings and utilities over a large area, whereas System/Application architects are focusing on the optimal construction of a small number of buildings and their optimal interfacing with the utilities they assume will be there at some point.
