Abstract: Over the last few years, interest in renting Cloud Infrastructure as a Service (IaaS) has increased and this has led to the development of many new solutions of this class. The competition on this market resulted in serious changes in the business strategies of the providers of IaaS cloud services. We are witnessing an incredibly dynamic development of the IaaS market. This requires the thorough analysis of the current possibilities of the providers of such products and the direction in which they will be developing in the near future.
The objectives of the present article are to analyse the characteristics, advantages and disadvantages of the IaaS solutions of the world’s leading providers of cloud services and to offer recommendations with reference to choosing an effective cloud configuration.
To achieve the set goals, the study has used the Gartner’s Magic Quadrant research methodology; has collected and summarised data from the studied providers of IaaS cloud services and, based on these results has outlined parameters that can be used to analyse, compare and assess the leading world IaaS solutions.
