I just had the opportunity to participate at the latest SOA Symposium focusing on the Department of Defense and other government agencies. The theme was on the people aspects of SOA and how success is directly measured by the amount of collaboration and teamwork in the project.
Vendor presentations by IBM, Microsoft, Oracle, Red Hat and Amberpoint talked to Cloud Computing, SAAS, Event Processing, Open-Source and Governance.
Separate to this I have had the opportunity to do some training and consulting in the area exposing me to the contracting base and additional government agencies. It is clear that data sharing between agencies appears to be increasing and currently service APIs are seen as the goal.
