Virtualization is the name for the cutting-edge computing technology that allows for one computer or server to act like many. What this means is that on one server you can host your databases, web sites, e-mail, and specialized applications server all on one physical machine. Then you only have to buy hardware once and maintain one machine. The machine can be made more powerful, bigger, faster, or even get a brand new one with no reconfiguration of your virtual servers. Virtual servers are stable, portable, and efficient. Availability and disaster recovery can all be made easier and cheaper with virtualization technology.

According to former Dell CEO Kevin Rollins approximate 70% to 80% of a business' technology budget is allotted to managing current systems and applications. This does not leave a significant budget for growth and research. A large source of these expenses is resources that are underutilized. An unused server is a useless server, so to speak. With virtualization technology Intel says that it's possible to save 28% to 53% of expenses on hardware and 72% to 79% on the cost of operation.  That's a significant savings but what if something were to happen to your location? Virtual machines can be migrated and mirrored over a network connection so that backup machines could reside remotely and start if the primary machines go down. Depending on the convergence of your network infrastructure this could result with no perceptible downtime to any of your users or other systems.
