The name Cloud computing was inspired by the Cloud symbol that's often used to represent the Internet in flow charts and diagrams. The term cloud computing is sometimes used to refer to a new paradigm – some authors even speak of a new technology – that offers IT resources and services over the Internet. The technology analysts at Gartner see cloud computing as a so-called "emerging technology "on its way to the hype[7].When looking at the number of searches for the word pair "cloud computing” undertaken with the Google search engine one can get a feeling of the high interest on the topic. Even terms like "outsourcing”, "Software-as-a-Service (SaaS)” or "grid computing” have already been overtaken.

Cloud Computing is becoming a well-known buzzword nowadays. In simple terms Cloud computing is where software applications, processing power, data and potentially even artificial intelligence are accessed over the Internet. Many private individuals now regularly use an online e-mail application such as Gmail, Yahoo Mail or Hotmail. Exchanging messages and sharing photos and video on social networking sites like Face book is now also very common. However, these types of cloud computing activities are just the beginning.
