VMware, Microsoft, Citrix, and Red Hat Cost Comparison

In part one of Cost to Build a New Virtualized Data Center, we discussed the basic software costs for a virtualized data center based on VMware vSphere 6.0, Citrix XenServer 6.5, Microsoft Hyper-V 2012 R2 and 2016, and Red Hat. If you missed that, please click here to review before continuing.

This post will take that original premise and expand it to include storage with a view to moving the entire environment toward a software-defined data center.

KVM in RHEL 5.4 – Red Hat leaps out of the virtual shadows.

On 2nd September (right in the middle of VMware’s VMWorld Conference in San Francisco) Red Hat, the dominant Linux vendor, announced (at its own Red Hat Summit in Chicago), that with its Red Hat Enterprise Linux 5.4 release it was “Setting the Virtualization Agenda”.  In another post we will look at the validity of this claim.  In this post we focus on the RHEL offering itself.
