AHP-Based Ranking of Cloud-Service Providers

The paper presents an approach to rank various Cloud-Service providers (CSPs) on the basis of four parameters, namely, Performance, Availability, Scalability and Accuracy, using Analytic Hierarchy Process (AHP). The CSPs were monitored by the cloud storage company named Nasuni and tests were conducted to evaluate the CSPs for the four parameters mentioned above. This paper makes use of the data provided by Nasuni to propose a method for ranking various CSPs. AHP has been selected for this purpose because it uses the foundations of mathematics and psychology to enable one to make complicated decisions. Instead of recommending a correct decision, AHP provides the decision makers with an opportunity to select the option that is most befitting to their goals.
