Server virtualisation is the latest trend in computing. Essentially it involves creating a multiple virtual versions of a physical server, contained within one physical guest server. The virtual machine acts like a real computer, and is controlled with an operating system. The host sever allocates resources the virtual servers as required by the computer users. The process reduces the number of physical servers required to manage an organisations IT Infrastructure.
Virtualisation can save an organisation a significant amount of money within their IT expenditure. The reduced requirement to purchase hardware, which needs to be replaced every few years, in addition to the lower cost of virtual software licences (as opposed to physical software licenses) is a large cost saver.
In addition Virtualisation also improves scalability as computer resource requirements can quickly be increased or decreased as required. Therefore, organisations are only required to pay for the computing resources actually required as opposed to purchasing multiple physical servers which may never fully be utilised. A reduction in the need for IT
Infrastructure through Virtualisation also reduces power costs, and reduces the space consumed by Servers and hardware.
Virtualisation is one of the emerging trends in IT and should be considered by all organisations looking to save both money and increase IT efficiency and redundancy.
