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

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 Benefits
High Utilization Rates for Server
Less Wasted Resources (storage, power, etc)
Quick Recovery from Downtime
Ability to Easily Provision Requested Resources
