I have heard about these solutions from Microsoft but really didn’t had time to make some advance search but today accidently I’ve found the web site that stores information about them:
Microsoft is committed to delivering customers a consistent platform regardless of deployment location and calls this vision the Cloud OS. As part of this strategy, Microsoft is now enabling Hosting Service Providers to use Windows Server and System Center to deliver the same great experiences already found in Windows Azure. The first two of these finished services are high density website hosting and virtual machine provisioning and management. Hosting Service Providers enable these modules through the new Service Management API and optional portal, which will continue to add more services from Microsoft and 3rd party providers over time.
