Virtualization is an amazing technology that has been with computing since its infancy. However, in recent years it has reached the mainstream on servers and desktops. Virtualization provides an abstraction of physical computing resources – such as cpu, network, and storage. Hence the term “virtual machine.” This allows for taking snapshots of running virtual machines as well as move these live systems from phsyical machine-to-machine!

Many data centers are only utilizing a fraction (10-20%) of their computing resources. To maximize workflow we virtualize the resources so they can be used more efficiently across more defined and scheduled processes. Excess resources can be shared with other applications, so they can be utilized. This can save companies millions of dollars in maintenance fees, administration, and computing costs.
