What is Virtualization?

Ability to run multiple operating system, with multiple applications at the same time, on the same system, without the need to reboot

Ability to “Virtualize” hardware into software

Ability to share virtualized hardware among different operating systems and software, at the same time

Why Virtualize?

Ability to Consolidate Servers

Smaller Physical Infrastructure

Ability to Quickly Provide Virtual Machines

Reduce I.T. Costs

Reduce Global Warming

History

I.B.M began (in 1970s) by virtualizing mainframes; allowing mainframes to multi-task.

Virtualization abandoned in the 80s and 90s, due to small and powerful individual desktop x86 machines.

With everyone owning their own personal computer, costs of maintenance went up: became expensive to maintain different users within an organization, all with their own PCs.

Virtual Machines & Virtual Servers

Multiple guest systems on one host

All guests isolated; as if they were separated systems

Hardware Independence

Encapsulation, making virtually machines easily transportable from one host to another

Virtual Infrastructure

Virtual Infrastructure Benefits

High Utilization Rates for Server

Less Wasted Resources (storage, power, etc)

Quick Recovery from Downtime

Ability to Easily Provision Requested Resources
