1.Virtualization
2.Strategy for web hosting
Reduce costs by consolidating services onto the fewest number of physical machines
Reduce costs by consolidating services onto the fewest number of physical machines
3.Virtualization Defined
Virtualization is a broad term that refers to the abstraction of resources across many aspects of computing
For our purposes - One physical machine to support multiple virtual machines that run in parallel.

4.Why Virtualization?
Too many servers for too little work
High infrastructure requirements
Limited flexibility in shared environments

7.Benefits of Virtualization
Reduce the number of physical machines
Isolate environments but share hardware
Make better use of existing capacity
Virtualize Network
Ultimately save on maintenance and leases

10. Core Technology
The Hypervisor
A computing layer which allows multiple operating systems to run on a host computer at the same time.
Originally developed in the 1970s as part of the IBM S/360
