Virtualization with Windows Server 2012

Microsoft just recently announced the release of Windows Server 2012.  You can find more on this announcement here ( ).

I wanted to take a moment to highlight some of the improvements in Server 2012, specifically around virtualization.  It is a fair statement that Microsoft has been playing a catch up game with virtualization over the first few years of the product existance.

That changed significantly, with Hyper-V on Server 2008, when customers saw an enterprise class hypervisor emerge.  It further improved with the release of Windows Server 2008 R2.   And now…with additions to Hyper-V on Server 2012, Microsoft is leading the industry in hypervisor specifications.  Have a look:
