When to Use the Windows Azure VM Role
For those ISVs trying to decide whether the new Windows Azure VM Role is a good feature to use in migrating a legacy application to Windows Azure here is a good article: The Proper Use of the VM Role in Windows Azure. The article was written by Microsoft Data Architect Buck Woody and posted on SQLblog.com.
In the article Buck recaps the functionality of each of the role types in Windows Azure (Web, Worker, VM). He also discusses the differences between Infrastructure as a Service (IaaS) and when the VM Role is or is not a good fit to use in a particular situation.
