Readings in Service Orientation
Service oriented architecture (SOA) is a big term these days. It can be interpreted in a lot of ways and can also be implemented in a different set of ways. Over the many months, the Architecture Journal from Microsoft has been publishing the Architecture Journal that carried various articles on Service Orientation concepts and patterns in that space.
Recently, I ran into this link that has collected various classical papers on Service Orientation and put in in a single PDF that you can then read to form your own thoughts about how to do Service Orientation. Its really cool and a great read! You can find it here: http://www.microsoft.com/downloads/details.aspx?FamilyID=4469946F-2723-47A2-9F54-6520DDAE3260&displaylang=en
