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

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

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

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

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.
