Tony Baer has an interesting post at http://www.onstrategies.com/blog/?p=251, 'SOA in a Recession?'. The question here is 'what will SOA investments look like during a recession?' Having been a part of the big client server moves of the mid to late 1990s, web deployments of 1997 to the present, and someone who has done training on SOA across the country for Wintellect, I have to say that SOA feels different from the previous two items. For client server, we had to start thinking about our applications differently. Bits of the application lived in different processes on different machines. Here, we had to rearchitect applications to deal with a new security model and to deal with the greater latencies involved in method and database calls.
