this morning I reviewed a few blog posts out there. There was one about how other virtualization vendors out there are pursuing VMware with a "it's cheaper that VMware" sales strategy.
Believe me, I have been around the virtualization market for a little while. As we all know x86 system virtualization now is a mission critical aspect of every organization's operations.
I have designed, implemented and worked with all the Tier I and II virtualization products out there and there is only one able to provide the kind of features, resiliency, management and performance required in a production environment. It is called VMWare ESX.
That's why you need to pay for VMware products. Other offerings (although "not bad"), overall simply do not offer a production ready state. In the future that may change but who on Earth would take the RISK to place their production systems on anything other than ESX right now?
