© 2018 IEEE. Reliability analysis of cloud is not a trivial task due to the complexity and scalability of cloud-based systems. This paper proposes a novel model for evaluating cloud reliability in an effective manner. To provide an appropriate evaluation model, this paper also outlines a classification strategy for cloud failures and considers several types of failures from different domains of cloud environment to properly evaluate the reliability. The effectiveness and applicability of the proposed evaluation model has been demonstrated through simulation results. The results show that execution stage failures have more influence on the cloud reliability than the request processing stage failures.
