  The research goal is to investigate the evolution of the concept of utility
computing in the works of foreign researchers in the years 1959-1966. First the
A. O. Mann's results and expanded overview of the D. F. Parkhill's results on
the concept of computer (information) utility were introduced in the domestic
scientific circulation. Functionally identity of the computer utility and cloud
computing concepts was proved, as well as refined the primary sources of cloud
service models. There was proposed the interpretation of the "cloud
technologies of learning" concept. Continuity of the development of cloud
technologies over the past 55 years and their relationship with the development
of ICT in general was concluded. The research results make it possible to
determine the prospects of the development of cloud computing in general and
cloud technologies of learning in particular.
