I co-authored an article titled 'Design Considerations for S+S and Cloud Computing' in this months Architecture Journal. I co-authored this along with 8 other architects at Microsoft. They were Fred Chong, Alejandro Miguel, Jason Hogg, Ulrich Homann, Brant Zwiefel, Danny Garber, Joshy Joseph and Scott Zimmerman.
Here is the summary: The purpose of this article is to share our thoughts about the design patterns for a new generation of applications that are referred to as Software plus Services, cloud computing, or hybrid computing. The article provides a view into S+S architectural considerations and patterns as they affect common architectural domains such as enterprise, software, and infrastructure architecture.
