2. INTRODUCTION
Virtualization is technology that allows you to create multiple simulated environments or
dedicated resources from a single, physical hardware system.
Creation of a virtual -- rather than actual -- version of something, such as an operating
system, a server, a storage device or network resources.
4. CONCEPT OF VIRTUALIZATION
Virtualization describes a technology in which an application, guest operating
system or data storage is abstracted away from the true underlying hardware or
software.
A great example of how virtualization works in your daily life is the separation of your hard drive
into different parts. It started as the ability to run multiple operating systems on one hardware set
and now it is a vital part of testing and cloud-based computing.
5. WHY?
❏ Isolation among users
❏ Resource sharing
❏ Dynamical resources
❏ Aggregation of resources
6. IS IT SECURE?
► Virtualization is an elegant solution to many common security problems.
► In a development environment, each developer can have their own sandbox,
immune from another developer’s rogue or runaway code.
► When VMs and applications are properly isolated, only one application on one OS is
affected by an attack.
7. HOW IT WORKS?
● Virtualization software makes it possible to run multiple operating systems and multiple
applications on the same server at the same time” – Mike Adams, VMware
● Provide applications with the standard versions to their cloud users.
● Normally in the cloud computing, users share the data present in the clouds like application
Virtualization users share the Infrastructure.

9. SECURITY
● Security is one of the important concerns.
● Prevents unauthorised access.
● Protection from Harmful viruses and Cyber threats.
● Encryption process:
It takes place with protocols which will protect the data from other threats.
10. ECONOMICAL
● Saves the cost for a physical system such as hardware and servers.
● Stores Data in Virtual server.
● Reduces the wastage, decreases the electricity bills.
11. FLEXIBLE OPERATIONS
● The network switch implemented today is very easy to use, flexible and saves time.
● It eliminates the problem of recovering the data from crashed or corrupted devices and hence
saves time.
12. FLEXIBLE DATA TRANSFER
● The data can transfer to the virtual server and retrieve anytime.
● Easy to locate the required data and transfer them.
● Additional storage is provided.
13. ELIMINATES RISK OF SYSTEM FAILURE
● Failure can cause damage to the company but the virtualizations help you to perform
the same task in multiple devices at the same time.
● Even if a server crashes with the help of the second server the customer can access the data.
