WHAT I S VIRTULIZATION?

Ability to run multiple virtual machines on asingle piece of hardware

Enables you to install multiple operating systems

These Multiple operating systems runsimultaneously and independently, in their ownsecure environment

Works with minimal reduction in performance

HISTORY OF VIRTUALIZATION

Concept- by Jim Rymarczyk(1960s)

Implemented by IBM

Reason - to maximize computers efficiency

Massive growth in the use of computer technology created new

problems, likePROBLEM : Low hardware utilization

SOLUTION : Hardware virtualization

HARDWARE VIRTUALIZATION

Most common & used in IT departments

It breaks one application one server barrier

Allow us to run different OS & different applicationsimultaneously on the same hardware

ARCHITECTURE OF FULL AND PARA VIRTUALIZATION


11/29

FULL VIRTUALIZATION Implemented using special software called HYPERVISOR

It provides complete independence of each virtual server to other virtual servers running on the same physicalmachine .

Para-virtualization Guest system can feel the presence of each other

OS level virtualization Does not include the use of a hypervisor

Hosting OS, performs all the functions of the hypervisor

ARCHITECTURE OF OS L EVEL VIRTUALIZATION


13/29

WHAT IS THE BEST METHOD ?

Same operating system OS-level virtualization.

Several different operating systems Para-virtualization.

OS virtualization is faster and more efficient than

other methods

DESKTOP VIRTUALIZATION


15/29

DESKTOP VIRTUALIZATION

Allows the use of virtual machines to let multiplenetwork subscribers maintain individualized desktops

on a single, centrally located computer or server

Involves encapsulation


16/29


17/29

DESKTOP MODEL CAN BE EMPLOYED IN FOLLOWING TWO WAYS ..

Remote Desktop Virtualization

(Server-Hosted )

Local Desktop Virtualization

(Client-Hosted )


18/29

S TORAGE VIRTUALIZATION :

Refers to the separation of logical storage from physical

storage

Allows the Systems Admin increased flexibility in how theymanage storage for end users

WHAT IS CLOUD COMPUTING ?

Cloud Computing is defined as a pool of virtualizedcomputer resources.

It involves delivering hosted services over theInternet.

Allows consumers to use applications withoutinstallation

Only Pay for What Yo u Us e


23/29

HOW VIRTUALIZATION IS RELATED TO CLOUDCOMPUTING

Cloud Computing is a collection of Virtualization Technique


24/29

HOW CLOUDS ARE FORMED BY USING VIRTUALIZATION TECHNIQUES

Key attributes :Sharing of infrastructure

Scalability and elasticity

AgilityLocal independence


25/29

T YPES OF CLOUD

Private

Virtual Private Cloud

Public(Example- Amazon Web Services is the largest public cloudprovider).

Cloud computing Application Component includes

FacebookMicrosoft OnlineGoogle Apps


26/29

THE BENEFITS

Access your data at all times not just while in the office

A physical storage center is no longer needed

Most have a pay structure that only calls for payment onlywhen used

Easily scalable so companies can add or subtract storagebased on their own needs


27/29

THE NEGATIVES

If you are going to move all of your information to data centers situated outsideyour company, then security should be of utmost importance.

If your cloud host disappears, where does

your information go?


28/29

VIRTUALIZATION UNLOCKS CLOUD COMPUTING

There are at least five things that

virtualization does to unlock the door tocloud computing :

Enables economies of scaleDecouples users from implementationSpeed, flexibility, agilityBreaks software pricing and licensingEnables, motivates chargeback
