Virtualization : How it Works
Virtualization is presently a key buzzword in the IT industry. In the early 90’s, it became apparent that virtualization could be the solution to the problem of underutilization of systems and increasing management costs. Today, virtualization is one of the hottest topics for enterprise IT. Around the globe, the largest enterprises are implementing various stages of virtualization. They are either using it, have it selectively implemented, or are planning how to use it.
How Virtualization Works
Virtualization is an isolated part or layer that divides the physical hardware resources and distributes them to the parts. This allows multiple virtual machines, with homogeneous or heterogeneous operating systems, to run concurrently on the same physical system. The physical resources from the physical system (CPU, RAM, NIC, disk space, etc.) are partitioned from the physical system and allocated to the virtual machines created. The operating system sees these virtual machines as independent operating systems with the distributed hardware resources to be their own hardware.
Virtual systems are consolidated into files; this makes it possible to move an entire system easily from one physical system to another. This provides the enterprise with some considerable advantages like backing up important data, or transfer a full server to another server.
