This document discusses virtualization and its benefits. Virtualization allows multiple virtual machines to run on a single physical machine, improving resource utilization. It describes two types of virtualization: para-virtualization and full virtualization. A virtual infrastructure consists of hypervisors, resource management services, and automation. Virtualization improves compatibility, isolation, hardware independence, and allows for dynamic resource allocation. It reduces costs, improves asset usage, enhances management, and increases flexibility.

3. Abstract
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.

4. Introduction
We 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

5. Types of Virtualization
PARA VIRTUALISATION
 FULL VIRTUALIZATION

6. With virtualization we can be
able to dynamically move resources
able to share resources
making better use of the resources
driving up utilization

7. How does Virtualization works

8. Virtual infrastructure

9. 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.

10. Benefits
Compatibility
Isolation
Encapsulation
Hardware Independence

14. 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.

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

18. Conclusion
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.
