Virtualisation, you may claim it is same as cloud computing but it is not. Cloud computing is wide and virtualisation is one of its features. Virtualisation can be a start for an organisation to go cloud. It is about moving our technology and implementations to a virtual server with no hardware present physically with us. You still store the data or use software applications but they are done with the help of virtual machines. When computer applications are virtualised or when those services are acquired via internet, is called cloud computing. Hence virtualisation acts as a path to cloud computing.
History of Virtualisation
IBM is the first to introduce virtualisation concept in 1960s but it was so expensive. In 1980s and 1990s , desktop computing and x86 servers replaced virtualisation then client-server applications and Windows and Linux needed high maintenance and management cost and had frequent breakdowns which led to the virtualisation of x86 platform by VMWare in 1990s. In 1999, VMWare introduced a system which transformed x86 into a fully isolated hardware infrastructure. Thehistory of virtualisation is referred from www.infobarrel.com.
Benefits of Virtualisation
Cost reduction and efficiency are the major benefits insisting the organisations to move to the virtual world. The cost to implement and maintain IT hardware is completely eliminated and has only the operating cost through subscriptions. It reduces the number of physical servers used by the company. The earlier technologies like x86 had high implementation and operational costs. This concept of virtualisation overcomes those disadvantages and offers more efficiency at a very less cost. It removes the liability to physical servers subject to natural disasters, power failures and accidental damages.
Virtualisation is not a new concept as IBM introduced it in 1960s but it is a hot topic to discuss how it directs the IT world. Virtualisation and Cloud computing stamped its name in the history of computing and seem to have a great future. May be, it should be described as the future of IT is in the hands of cloud computing. In the age of cloud computing, unless you are a technology company, you do not invest in technologies, rather you direct those huge investments towards other facilities or operations. With reduced cost, increased efficiency and data reliability, it is time to plan the level of virtualisation and strategy to virtualise your company rather than thinking whether to go virtual or not.
