A hypervisor, also called a virtual machine manager, is a program that allows multiple operating systems to share a single hardware host. Each operating system appears to have the host’s processor, memory, and other resources all to itself; however, the hypervisor is actually controlling the host processor and resources, allocating what is needed to each operating system in turn and making sure that the guest operating systems (called virtual machines) cannot disrupt each other.

Mark’s team was asked to take charge of a series of live global enterprise systems for both 7×24 support and extensive new code developments. They came up to speed very quickly and were both responsive and helpful in all aspects that they became involved with. Significant steps were taken to improve these systems while Mark’s organization was involved and we have nothing but positive inputs to provide as to their service levels and final outputs.
