Benefits of consolidating servers

Hardware was expensive, and there was not that much available.Processing was largely outsourced to the few places that did have computers.Guest operating systems running in a Hyper-V virtual machine provide performance approaching the performance of an operating system running on physical hardware the necessary virtual server client (VSC) drivers and services are installed on the guest operating system.Hyper-V virtual server client (VSC) code, also known as Hyper-V enlightened I/O, enables direct access to the Hyper-V “Virtual Machine Bus” and is available with the installation of Hyper-V integration services.At first glance it appears that not much has changed.Today the main application of virtualization technology in the enterprise is to combat server sprawl through virtualization-based consolidation.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's a huge opportunity for IT budget savings by reducing IT labour requirements – primarily administration and support.

Virtualization breaks the 1:1 relationship between applications and the operating system and between the operating system and the hardware.
