Cloud Service Provider Selection: A Complex Multi-Criteria Decision Making Problem

Abstract

Cloud computing is a large pool of virtualized resources that provides an on-demand, pay-as-you-go computing resources and scale economies. These advantages force many of organizations to migrate their in-house business to cloud based computing. It delivers the IT enabled capabilities as a service to any needed users over the internet. Contrasting several cloud service providers in terms of both price and quality has become challenging due to the growing number of cloud providers, their vast array of services, and their wildly disparate pricing models. Potential cloud consumers now have a more difficult time selecting a service and provider because of the variety of services and the abundance of alternatives accessible. Various multi-criteria decision making (MCDM) techniques have applied by researchers for service and provider selection. This paper focuses mainly on the different MCDM approaches that are existing, and comparative study of all the approach together as a literature survey.
