Virtualization is a proven software technology that is
rapidly transforming the IT landscape and fundamentally changing
the way that people compute. Today’s powerful x86 computer
hardware was designed to run a single operating system and a
single application. This leaves most machines vastly underutilized.
Virtualization lets you run multiple virtual machines on a single
physical machine, sharing the resources of that single computer
across multiple environments.

IntroductionWe are familiar with the concept of multiple
processes running simultaneously and sharing the resources of a single computer. This is achieved by operating system acting as a single point of contact interfacing with the hardware resources, and there by controlling the access to hardware resources by multiple processes.
Virtualization can be thought of as an extension of this concept, where in multiple operating systems are allowed to share the hardware simultaneously by means of virtualization software

With virtualization we can be
able to dynamically move resources able to share resourcesmaking better use of the resourcesdriving up utilization

How does Virtualization works

Virtual infrastructure
![Page 9: PLAT FORM VIRTUALIZATION](https://reader036.vdocuments.net/reader036/viewer/2022062616/5498da9eb4795905028b45dc/html5/thumbnails/9.jpg)
A virtual infrastructure consists of the following components:
Bare-metal hypervisors to enable full virtualization of each x86 computer. Virtual infrastructure services such as resource management and consolidated backup to optimize available resources among virtual machines Automation solutions that provide special capabilities to optimize a particular IT process such as provisioning or disaster recovery.

How virtualization complements new-generation hardware
Extensive ‘scale-out’ and multi-tier application architectures
are becoming increasingly common, and the adoption of smaller
form-factor blade servers is growing dramatically. Since the
transition to blade architectures is generally driven by a desire for
physical consolidation of IT resources, virtualization is an ideal
complement for blade servers, delivering benefits such as
resource optimization, operational efficiency and rapid
provisioning.

Why virtualization?
Reduce Costs
Improve asset utilization
Enhance management
Increase flexibility
Allow faster resource deployment
Allow faster resource deployment
Gain operational flexibility:

Virtualization enables us to run more than one
operating system at once.
Hence it is very easy for a programmer to evaluate his
program simultaneously in different operating
system.
It becomes easy for various organizations to provide a
new desktop for a newcomer with existing
resources.
Effective utilization of resources.
