Virtualisation is – getting more for less.
Most organisations use individual servers to host no more than a single application. This causes significant overspending on capital and operating costs, inefficient performance and underutilisation (analysts estimate less than 10% utilisation is common). Virtualisation allows server hardware to be used more efficiently with resources being dynamically allocated to applications on demand. Each application can be run in a separate virtual environment, leading to fewer servers, fewer racks, less power, reduced operating costs and an overall reduction in your IT footprint.
Benefits of Virtualisation:
- Reduce the total cost of ownership – less servers, less racks, less maintenance, less power draw, server consolidation, less admin costs.
- Increase current hardware utilisation – use existing hardware, applications only operate on demand, reduce idle time, cluster similar applications.
- Business continuity – recreate servers, easier software migration, clone existing server configs, minimum disruption, maximum utilisation.
- Reduce security risks and increase manageability – common security environments, share systems without sharing sensitive data, secure isolated testing, fast restore of infected systems, centralisation, allow legacy to exist alongside virtual.
- Improve application performance – shared resources capable of handling unexpected demand, no need for spare capacity to cope, flexibility to reassign resources as required.
- Reduce
network utilisation – bandwidth
used as and when demand requires.
