Instruction Set Virtualization What is Virtualization? Why Virtualize? History Virtual Machines & Virtual Servers Virtual Infrastructure Screen-shots Demo: Running Ubuntu on Windows
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
