What is a virtual machine?
A virtual machine is a software container that can run its own operating systems and applications as if it were a physical computer. A virtual machine behaves exactly like a physical computer and contains its own virtual (i.e., software-based) CPU, RAM hard disk and network interface card allowing you to run multiple virtual PC’s or Servers from one physical machine.
An operating system can’t tell the difference between a virtual machine and a physical machine, nor can applications or other computers on a network. Even the virtual machine thinks it is a “real” computer. Nevertheless, a virtual machine is composed entirely of software and contains no hardware components whatsoever. As a result, virtual machines offer a number of distinct advantages over physical hardware.
The performance gap between virtual servers and dedicated servers has narrowed considerably. Many of our customers are replacing their dedicated servers with our low cost virtual server solutions. To Improve the efficiency and availability of IT resources and applications through virtualization. Start by eliminating the old “one server, one application” model and run multiple virtual machines on each physical machine.
