The VMware Performance Team has repeatedly demonstrated how vSphere is the superior platform for your production workloads. Check out the latest article on the VROOM! blog for all the details.
By running substantially more virtual machines per hypervisor host, VMware provides the lowest cost per application — even less expensive than so-called “free” virtualization solutions.
You might be tempted to compare this tremendous success with first-generation offerings from other virtualization vendors, such as Citrix WLB or SCVMM PRO Tips.
