Figure 1 - Non Virtual Machine and VM Configurations The VMM is the control system at the core of virtualization.
There's a huge opportunity for IT budget savings by reducing IT labour requirements – primarily administration and support.
The creation and management of virtual machines has been called "platform virtualization", or "server virtualization", more recently.
Platform virtualization is performed on a given hardware platform by host software (a control program), which creates a simulated computer environment, a virtual machine (VM), for its guest software.
Hardware was expensive, and there was not that much available.
Processing was largely outsourced to the few places that did have computers.
Virtualization hides the physical characteristics of a computing platform from the users, presenting instead another abstract computing platform.Virtualization often exacts performance penalties, both in resources required to run the hypervisor, and as well as in reduced performance on the virtual machine compared to running native on the physical machine.However, when multiple VMs are concurrently running on the same physical host, each VM may exhibit a varying and unstable performance, which highly depends on the workload imposed on the system by other VMs, unless proper techniques are used for temporal isolation among virtual machines.There are many compelling reasons to consider deploying a production Biz Talk Server solution in a Hyper-V virtualized environment.While there is some performance overhead associated with the virtualization layer that enables running a guest operating system on a virtual machine, one of the primary design goals of Hyper-V was to minimize this overhead and therefore maximize performance of guest operating systems.
