Windows Cloud Computing
Running a Windows environment in a public or private cloud
Cloud computing infrastructure (IaaS) providers support all operating systems. And many say they are OS agnostic. They don't care which platform you use.
Of course, there are many differences between hosting providers and some will work better within the Windows platform. One of your first vendors to consider for a cloud computing deployment is Microsoft. The Windows Azure platform provides the same on-demand hosting services you can find from a wide variety of vendors.
Microsoft Windows Azure is sold on a metered basis: you pay only for what you use. And because Microsoft is providing the hardware, and cloud platform, it is easy to test it before committing a significant amount of your hosting business.
