Virtualization (Windows) basically refers to the construct of computer resources. This process puts out of sight the physical characteristics of computer resources from respective users; whether they’d be potential end-users or applications. Virtualization includes the creation of a single physical resource, which can either be the operating system, application, storage equipment, or server.

Specifically, the physical resource may seemingly function as multiple virtual resources instead. Likewise, it can also include creating other more multiple physical resources that appear as single virtual resource. These physical resources may be as storage devices or servers.

Moreover, virtualization allows the running of multiple systems on current hardware with high performance features. Hence, instead of having seven machines all running at 10% usage, a single machine that runs at 70% usage can be sufficient already. Hardware technologies that are now available include IBM Advanced POWER virtualization, AMD Pacifica x86 virtualization, Intel Vanderpool x86 virtualization, Sun Microsystems UltraSPARC T1 hypervisor, and Hitachi’s Virtage hardware virtualization.

In addition to the savings obtained from hardware usage, there are also savings gained in terms of space, power, and cooling system. This is because lesser machines are being run. Another savings obtained come from staff savings, which only means that an organization would require lesser number of working administrators since there are rather fewer machines available for use.

Lastly, virtualization is commonly used in various contexts. Such contexts can then be classified into two main categories. These categories include 1) platform virtualization, which involve the simulation of whole computers; and 2) resource virtualization, which involve the simulation of fragmented, simplified, or combined resources. Amazingly, virtualization only provides effortless running and management of computers and other more resources while simultaneously reducing or saving various costs by the organization.
