SOLUTION• Future of Virtualization

HISTORY OF VIRTUALIZATION• Inconvenient interaction of computer

with user.• Developed by IBM in 1970’s – CP-40• CP-40 : FIRST VIRTUALIZED MAIN

FRAME COMPUTER• CP/CMS to support virtual machine.

DEFINING VIRTUALIZATION:

• Virtualization > a process of mapping resources & interfaces of virtual resource

on the host machine.• Introducing the technology and concept of

a world of machines within a machine.

HOW DOES VIRTUALIZATION

WORKS…

HOW DOES IT WORK?Services & apps

runs on Host O.S. Virtualization is

one of the service

Guest O.S. runs on virtualization

software

Spoofing of resources take

place

Emulation of Hardware take

place

Sandboxing going on….

Extra load of G.O.S. handled

by H.O.S.

Virtualization & cloud Computing

• Both developed Follow #MORE WITH LESS.• Virtualization- A Part of Infrastructure.

Cloud Computing- A service.• Virtualization- Profitable for long run

Cloud Computing- Profitable for short run.

VIRTUALIZATION SOFTWARE: FEATURES TO LOOK FOR• Ability to take advantage of hardware features• Stability• Lower resource usage.• Good support for virtual hardware in use.• Networking facilities.• Snapshots.• Remote accessibility.• Ease of use and shared folders.

So its demo time…..Test:

VIRTUALIZATION supports my machine or not???

VMware workstation

VIRTUALIZATION IN REAL WORLD

• Upgrading gets easier• Scalability• Saving software costs• Resource sharing• Recovery• Fault-tolerance

VIRTUAL MACHINES ARE NOT TOTAL SOLUTION

• Demand of powerful machine.• Is Performance Same?• It’s not Easy – Complicated• Not Supported by All Applications

FUTURE OF

FUTURE OF VIRTUALIZATION

• VDIworks 2013 Prediction: The Year to Make Good on VDI Promises

Gartner's prediction of 49 million VDI users in 2013

• Barrier to future of virtualization are

1. training about management, deployment.• Still Vendors are seeking for gain part in

apps validation space.
