A Bibliometric Analysis of Cloud Computing Technology Research

Cloud computing involves multidisciplinary development and integration, and is the result of information technology and related applications. In this study, Web of Science Core Collection database is used as data source. Using Excel, Bibexcel, VOSviewer and CiteSpace software for data mining and quantitative analysis of the 2005–2018 year research papers on cloud computing, we explore the trend of change, the distribution of research forces, key areas, research hot spots and international cooperation. The results show that the number of documents in cloud computing has been growing, and there are many subjects involved in the research of cloud computing technology, mainly Computer Science, Engineering and Telecommunications. There are many research papers on cloud computing in China and the United States; China is most prominent in international cooperation and has strong cooperative relations with the major countries; Chinese Academy of Sciences is very active in the research of cloud computing, and its papers are far ahead of other institutions. The main focuses of the study are virtualization, mobile cloud computing, big data, security, etc. The main hot spots of research are mobile cloud computing, big data, fog computing, secure, storage, access control, sever consolidation, etc.
