Best of TechEd 2013 – What’s New in Hyper-V in Windows Server 2012 R2

Didn’t make it to TechEd this year? Don’t worry!  This month, we’ll be releasing a new article series that highlights the Best of TechEd announcements and technical information for IT Pros.  Today’s article focuses on enhancements in Hyper-V server virtualization in the upcoming Windows Server 2012 R2 release.

Last week at TechEd 2013 North America, we announced Windows Server 2012 R2 – the next major release of Windows Server! We’ve already made significant virtualization improvements around Hyper-V in Windows Server 2012 – across the board, including scale, availability, management, storage, networking – BUT there’s a TON of new and enhanced capabilities planned for Hyper-V in the forthcoming Windows Server 2012 R2 release. 

In this article, we’ll provide an overview of these enhancements. After you review these new capabilities, I’m sure you’ll see why the R2 release is a MAJOR RELEASE – so MUCH MORE than “just another” Service Pack release!

Hyper-V – What’s New in Windows Server 2012 R2

Ben Armstrong, Hyper-V Program Manager, delivered an outstanding session at TechEd 2013 that provides an overview of the new and enhanced Hyper-V virtualization capabilities that will be available in Windows Server 2012 R2.  Below, I’ve provided a clickable index to Ben’s recorded session, so that you can easily concentrate on learning about the areas that are most important to your environment.
