Some aspects of cloud computing efficiency estimation

The article is devoted to the effectiveness evaluation of the cloud technologies taking into account their specifics. The main characteristics and features of cloud technologies affecting their efficiency are considered. The generalized and partial performance indicators, taking into account the risks and vulnerabilities in the implementation of cloud technologies, are proposed. Mathematical models of cloud technologies efficiency indicators used in calculations are presented. A method of evaluating the effectiveness of cloud technologies, using a set of quantitative data characterizing all aspects of technology, combined with the use of expert assessments is developed. An example of evaluating the economic efficiency of cloud technologies implementation is given.
