Cloud Computing Whitepaper
'Cloud computing' is a term many people have heard, though few fully understand what it actually means. Even fewer still understand the impact the cloud will have on their business, and the importance of fully understanding this shift in IT services. Garter, the IT research and advisory company, believe the cloud computing market is a big opportunity for many companies, and predict it will grow from $36 billion in 2009 to over $160 billion by 2015.
The word 'Cloud' has long been used in IT circles to describe large networks of computers. However it was the CEO of Google who popularised the term 'cloud computing' in 2006, during a search engine conference. Since then its use in everyday language has exploded. So what does it actually mean?Cloud computing can be described as the means of delivering software and/or hardware, as a service, via a computer network such as the internet. Put simply, users can harness the power of a computer located somewhere out on the internet. This computer may be used for its number crunching horsepower, e.g. to process particularly complex mathematical calculations. Or it may be used to serve up software that the user otherwise doesn't have access to, e.g. using Google Docs over the web instead of buying Microsoft Office.
