The evolution of cloud technology began in the 1950s with the introduction of mainframes at IBM. A mainframe is a server with a large amount of RAM and external memory. It is designed to solve problems related to the processing of large amounts of data. The operators of these machines have the ability to access the central computer through terminals, the only function of which was to provide access to additional operators to the mainframes. In most cases, the user did not need the full power of the mainframe. Therefore, «stupid» ports have made mainframes more costeffective, and cloud technologies have a chance for further development.
The idea of an «intergalactic computer network» first originated in the 1960s with Joseph Licklider. He was responsible for setting up the Advanced Research Projects Agency (ARPANET) network. The essence of his concept was that all users from anywhere in the world should be interconnected and access programs and data on any site. The very idea of cloud services is associated with John McCarthy, a specialist in the theory of electronic computers. He suggested that computer computing would be available as a service in the future. This concept will form the basis of the SaaS model, which provides cloud software as a public service.
