FUD is “Fear, Uncertainty, and Doubt”. FUD is when people make assertions or statements that simply’re trying to scare people away from what they’re attacking. FUD spreaded about Hyper-V is for one purpose, To get you not to try Hyper-V and System Center. Very few FUD articles say something like “Try both solutions out and compare”. They all basically “It’s not worth your time to try it, trust me” or “You might try it a little but don’t deploy it as it’s very risky and your business might suffer because of it.” This goes against most basic point, which’s to try Microsoft Virtualization , evaluate it, deploy it for workloads, ask others who have deployed it in, and see for yourself. Here’s a summary of Edwin’s points: • You do not need to remove or replace your existing VMware installation to deploy Hyper-V • Hyper-V and the rest of Microsoft Virtualization is “Enterprise ready” for hundreds of companies today • Virtual Machine Manager is not a replacement for vCenter • Hyper-V is a mature, safe, secure hypervisor.
