With those heavy-duty features in place, it's a good time to look at how viable Hyper-V is as an alternative to VMware's market-leading ESX server virtualization platform. Below, we compare ESX with Hyper-V feature sets in eight critical categories
VMware has a big lead. In our August InformationWeek Analytics survey on virtualization management, in which we asked 316 business technology professionals which hypervisor is their organizations' main virtualization platform, 54% said ESX Server, 15% Hyper-V, and 7% Citrix XenServer.
Two declarations up front. One, I'm a virtualization engineer certified on VMware's vSphere 4.0 and have worked on many VMware implementations. That said, I approached this analysis determined to compare the two systems objectively. Two, the degree of functionality in the Microsoft offering surprised me. VMware is substantially more mature, but Hyper-V is a viable virtualization option now, and it's only going to get better.
