Over the past few years, virtualization has transformed the traditional data center. Countless businesses have reduced energy and hardware costs as more IT professionals realize the benefits of virtualization. For companies that demand more computing power, virtualization can help deliver improved performance without the need for an expanded facility or additional cooling infrastructure. Improved efficiency and reduced power use can easily be realized when multiple virtual machines (VMs) run on one server. Fewer physical servers and a smaller facility translate to lower overhead costs–put simply, virtualization allows businesses to do more with less.
