Abstract

Cloud computing offers various services to cloud users, including IaaS, PaaS and SaaS. These services are selected according to cost, availability, performance etc. The selection of a suitable cloud service becomes a complex decision-making problem for a cloud service user because of multiple alternatives and criteria. Multi-criteria decision making is a sub-field in operation research that deals with the techniques to solve such selection problems. This paper presents cloud provider selection problem for IaaS and PaaS using multicriteria decision-making techniques. Paper presents four case studies for IaaS and PaaS cloud provider selection. In these case studies we have taken different alternatives and criteria depending on that application. Results of Simple Additive Weighting (SAW), Weighted Product Method (WPM), Analytical Hierarchy Process (AHP), Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), VIKOR, PROMETHEE and Data Envelopment Analysis (DEA) techniques are compared. The ranking suggested by different MCDM methods are different but in majority cases first ranked alternative is same.

Keywords- Cloud service provider selection, multi-criteria decision making.
