Comparing IaaS providers present in the market: using hybrid intuitionistic fuzzy technique combined with TOPSIS

Abstract

In the past few years, cloud computing has advanced rapidly because of the increased demand of data centers and their services. The most basic category of Cloud computing is Infrastructure as a Service (IaaS) which is the process of providing the infrastructure such as networking hardware, storage media, etc. to the clients over the internet by the service provider on a pay-as-you-use basis. The major challenge faced by the clients is to choose among the many IaaS providers available in the market as to who can provide the best services keeping in mind certain criteria. This paper’s main objective is to compare five IaaS providers present in the market on the basis of factors like cost, reliability, scalability and security to efficiently choose the most appropriate IaaS provider for their preferred services. The major factor of concern in this paper is cloud security while the other factors have a partial impact on the final decision. The methodology adopted is a hybrid intuitionistic fuzzy technique combined with TOPSIS method so as to rank the given alternatives
