Microsoft announced the general availability of Windows Server 2012 today, describing it as the company’s first “cloud operating system” in a series of launch webcasts. There were lots of digs at VMware and fairly so since Microsoft has been taking share from the virtualization kingpin following the vRAM pricing debacle. Satya Nadella, president of Microsoft’s Servers and Tools Business referenced Pella Windows, a manufacturer of windows and doors, which switched from VMware to Microsoft to avoid the heavy price tag synonymous with VMware licensing. The biggest claim to fame Microsoft made with the new OS is that it offers users a single platform spanning their internal servers and external servers in Microsoft’s public cloud service, Windows Azure. That was about all it said on this though. I was expecting to hear more about the use case for migrating between public and private clouds, and what this portability means for Windows shops, but like the rest of the market, Microsoft isn’t quite there yet.
