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 %

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

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

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

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).

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

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

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.
