This is a great article about Service Oriented Architecture, by Microsoft Architect, Pat Helland. Service Oriented Architecture is not just for architects. It is the starting blocks for adopting Web Service Extensions (WSE 2.0), Indigo and other technologies. I am currently at a Microsoft Airlift, where people are invited to converge on Redmond and learn about technologies. I am currently learning about Connected Systems. Connected Systems describes how groups of products work together to allow for collaborative and connected data from systems to work together.
