Virtualization Defined
Definitions of Virtualization by users and experts.
| Virtualization |
| Virtualization is software that separates an application from the underlying physical hardware on which it runs. It allows a single piece of hardware such as a server to support many applications, thereby running the software more efficiently and at lower cost. |

| Virtualization: - [Is an] Extension of the concepts used in traditional mainframe environments into the distributed computing/server environment. - Allows multiple virtual machines to share the resources of a single physical machine. - Processor, Memory, disk storage, and network controller resources on a single physical machine can be virtualized and seamlessly shared across multiple virtual machines - each of which are seen as dedicated hardware resources to the operating systems running within the virtual machines. |

| Test Optimization Using Software Virtualization |
| What is virtualization? - Multiple OS or "Virtual Machines" installed on one physical machine. - VMs run in parallel to one another - VMs don't realized they are virtualized - Each VM is isolated from the others - The host simulates a hardware environment for each VM - 'Guest' OS may vary in type - Limited only by hardware |
