Cloud Computing: An Establish Model with a 40-Year Pedigree
Although Cloud Computing is touted as a new way of delivering applications, Cloud Computing has been an established business model since the 1960s when it was called a "time sharing system". In the time-sharing model, several "dumb" terminals (keyboards and monitors lacking CPUs) were networked to a mainframe or mini-computer, usually in a hub-and-spoke topology. Applications and data resided on the mainframe. Input was received via the terminal keyboard and output was then directed to the appropriate terminal monitor.
