Abstract
In recent years, special attention has been paid to the training system focused on the formation of digital skills. Cloudbased training allows solving a number of issues with storing the results of training activities and organizing access to them. For this, it is necessary to teach future teachers of computer science the principles of cloud technologies, the use of «clouds» in solving pedagogical problems. In this regard, it is necessary to determine the content of teaching cloud technologies for future teachers of computer science. The article discusses the principles of determining the content of teaching cloud technologies for future teachers of computer science. The authors define the principle of «cloudiness» as one of the leading principles for building a system of teaching cloud technologies and teaching in general. The goals and objectives of training are determined, the content of training in cloud technologies is disclosed.
