Cloud Architecture Patterns by Bill Wilder is a really good book. After some not so amazing reading recently i was much more skeptical when i got this book but it turned out to be a really great read. It is a no-nonsense approach to scalability and cloud software especially if you plan to host your application on Windows Azure.
