With the release of Microsoft Windows Server 2008 R2, the best server operating system on the planet got 1000% better. The list of impreovements are too numerous to detail here, but the ones I am most enamored with are DirectAccess, File Classification Infrastructure, Failover Clustering, BranchCache, and AppFabric.

* VMWare Vsphere. We do not have enough expertise with (market-leading) VMWare to definitively make a recommendation. However, I can count on several friends who are specialists in the product to recommend it. Furthermore, John Troyer, a social media specialist with VMWare, was kind enough to send recommendations my way in order to get my lead virtualization specialist on his way to gaining enough competence in the product so we might see if we should add it to our current virtualization offering.
