The goal of this publication is to analyze innovative solutions and international practices of using cloud-based scientific services and to classify them depending on the stage of research and the type of activity. The novelty of the study is that using the cloud computing technology is a promising area for the development and improvement of the scientific environment; this concept is a unified method of a common platform, a basis for the development, testing, and improvement of the Information and Communication Technologies (ICT) and electronic educational resources. The relevance of the formation and development of research environment based on the cloud computing technology has been substantiated, and the use of scientific cloud services has been analyzed in the article. The scientific services have been classified depending on the stage of research and the type of activity based on the analysis of scientific literature and expert survey, and the features of various areas of application of cloud services in research activities have been determined. © 2019, Institute of Advanced Scientific Research, Inc.
