I just read this article : Windows Azure: General Availability of Infrastructure as a Service (IaaS).
You can also sign up for a free trial.
And for MVP’s, with your MSDN, you can have a VM with 2 CPU’s permanently on-line.
I have one since July 2012 and use it for testing and I am very happy with it!
What is it?
In short : it is a VM like another running on commodity hardware, so don’t expect super-performance on it (commodity but you can add lots of memory and CPU’s).
