Due to the exponential growth in computing power, today’s servers are often overkill for the demands placed upon them. This means that expensive hardware can often exist in close to an idle state, completely underutilised when compared with its potential. Virtualisation can unlock that potential by enabling physical server hardware to run multiple virtual servers concurrently.

If you’re thinking about server and/or infrastructure upgrades then virtualisation can offer the following benefits:

Consolidation: Running multiple virtual servers across physical hosts enables a consolidation of server hardware and the decommissioning of older, less efficient legacy hardware. In turn this reduces power, cooling and space requirements of server rooms.

Operating system independence: Each virtual server can run a different operating system enabling Microsoft Windows and Linux to co-exist on the same hardware.

Application segregation: Running intensive or critical applications such as Management Information Systems in their own virtual machines can increase reliability by ensuring other applications are unable to interfere with the stability of the underlying operating system.

High availability: The virtual environment can monitor the heartbeat of virtual servers and automatically restart any that are unresponsive. In the event of a physical server failure the environment can restart virtual machines on other available hardware.

Flexibility: Servers become files on storage devices that can easily be moved between hardware, backed up, cloned and even turned in to templates for consistent, repeatable provisioning.
