I’m intrigued by the notion of Rackspace selling Windows Azure, whether it’s done on dedicated hardware or as a publicly hosted service. For one, it indicates there might be something to Microsoft’s strategy with the Windows Azure Appliance. As you’ll see in my weekly column (check back here on Sunday), a broad enough pool of providers could put Azure on the path to mirroring the success of the Windows OS. It also could mean trouble for Amazon Web Services. Don’t get me wrong, AWS is no weak offering, but if Rackspace could create a hybrid environment comprised of dedicated hosting, its Rackspace Cloud offerings and Windows Azure, that would truly be something.
