The buzz term that came into popularity in the beginning of 2006 to describe an innovative IT deployment architecture, originated from the metaphor that was used to represent the Internet in various network diagrams as early as the 1990s. In a short period of time after the term appeared, solutions were being rapidly marketed by many IT companies and various new buzz words came into vogue such as cloud in a can, cloud bursting, and we suddenly had “blue clouds”, “green clouds”, “white label services” and many others.
