A non-parametric data envelopment analysis approach for cloud services evaluation

Abstract

Due to advantages of cloud computing, services are increasingly deployed in cloud. It is a challenge to choose a proper service. Besides QoS requirements, customers expect more efficient services which provide better performance but with minimum cost. In this paper, we propose a non-parametric method to evaluate relative efficiency of cloud services based on Data Envelopment Analysis. It can classify cloud services into different efficiency levels and tell how to improve less efficient services. We illustrate the method with a case study.
