After a frustrating weekend, today I was scouting the Internet for virtualization news and I ran into a very interesting post by Jason Boche.

This morning VMware released their Cost-Per-Application-Calculator. With this calculator you can accurately estimate and compare acquisition cost of a virtualization solution, by VMware labeled as Cost Per Application. This is a great tool which will come in handy in current discussions regarding ‘free’ hypervisors.

If you want to know more about this VMware Cost-Per-Application-Calculator visit Jason’s blog and read the original article.

Based on some numbers from my current client case here are some results from the calculator.

Based on your inputs, the cost-per-application to virtualize 350 applications using VMware Infrastructure 3 Enterprise Edition is $2,867 — 11% lower than with Microsoft Windows Server 2008 (Hyper-V) and System Center.
