INTRODUCTIONAmong the leading business challenges confronting CIOs and IT managers today are:
• cost-effective utilization of IT infrastructure,• responsiveness in supporting new business
initiatives,• flexibility in adapting to organizational changes,
Virtualization is a fundamental technological innovation that allows skilled IT managers to deploy creative solutions to such business challenges.

WHAT’S VIRTUALIZATION ?
virtualization refers to physical abstraction of computing resources
the physical resources allocated to a VM are abstracted from their physical equivalents
Virtual disks
virtual network interface
cards
virtual CPUs
virtual memory
all map to physical resources on a physical computer system.

WHY VIRTUALIZATION ?
Today, many data centers have machines running at only 10 or 15 percent of total processing capacity.
85 or 90 percent of the machine’s power is unused
15 %
85 %
Money Places Energy consumed Time

WHY VIRTUALIZATION ?
With virtualization you’ll save significant money on hardware, power, and possibly IT staff.
the practical aspect of virtualization:• Minimize hardware costs• Provide disaster recovery• Consolidate idle workloads• Balance loads• Test software• Centralize server management• Conserve power• Deploy servers faster

SERVER VIRTUALIZATION
Virtual server (system) is like a physical server, is dedicated to a job or jobs for which it is designed.

Configuring a virtual server is much the same as configuring a physical dedicated server.

APPLYING VIRTUALIZATION
APPLICATION VIRTUALIZATION
13
DESKTOP VIRTUALIZATION
Desktop virtualization is moving a desktop operating system from local hardware to a remote server system.
remote desktop is accessed by using some lightweight client in the form of a small or minimal operating system
Smart Terminal
Dumb Terminal

DESKTOP VIRTUALIZATION
Hosted Web Desktop Systems
The newest entry into the desktop virtualization world. You can access your desktop from anywhere with a web browser.
Application virtualization can improve portability, manageability, and compatibility of an application
15
APPLICATION VIRTUALIZATION
Virtualization Applications
Applications installed and used on remote server systems through a browser or specialized client. Word processing, databases, customer relationship management (CRM).

APPLYING VIRTUALIZATION
NETWORK AND STORAGE VIRTUALIZATION

NETWORK VIRTUALIZATION
VIRTUAL PRIVATE NETWORK
(VPN)
VPNs are still the accepted method to connect remote users and remote offices to a central office network because they are secure and efficient.
There are several ways to implement a VPN service for a network
Hardware VPN

Software VPN

NETWORK VIRTUALIZATION
Virtual Local Area Network(VLAN)
VLANs are used on larger networks to segment, or isolate, traffic into separatebroadcast domains
VLANs are usually created using intelligent switches, but you can also create them with:
Standard VLAN
VMware VLAN
19
STORAGE VIRTUALIZATION
SAN AND VSAN•Storage area networking•Virtual Storage area networking
Server-based storage is traditional file server storage where you are connected permanently to a server that shares its local disks to users for file storage
Data Transportation
NASNetwork attached storage

DEMONSTRATION
Installing Virtual Machine : Vmware Workstation
Installing Linux and Windows Xp
Set up Web server Apache on every machine
Testing the connectivity to these servers
Implement Load Balancing solution with pound
CONCLUSION
Even though virtualization is a software technology, it has the effect of making hardware more important.
removing lots of servers
migrating their operating systems to virtual machines
Hardware environment becomes more important.
