Cloud computing has been defined as the provision of on-demand, IT resources using a ‘pay as you go’ service. This covers network based services as well as tools, which are provided by virtual servers. This is easily done by simulating the software running on one, or more computers. Cloud computing has rapidly evolved because the servers don’t actually exist and so are easily expanded or minimized without causing any problems to the user.
Cloud computing allows startups to save on infrastructure costs. Because the servers are not physically there, companies also save on office space. Providers allow companies to run their applications quickly and effectively.
