With the expansion of scale and the increase of users, the reliability of the cloud system has got more and more attention in the industry and academia. Services may be interrupted by random resource failures (such as network failure, virtual machine (VM)failure)in a realistic scenario. Many researchers have studied the reliability of cloud systems. However, in a cloud system, few of them propose a general sustainable platform to evaluate the effect of reliability on other quality of service (QoS)factor, such as energy, performance, ea.tl. To solve this problem, we first introduce two typical reliability factors including VM failure and server failure. Secondly, we give the design and realization of reliability simulation of cloud system in CloudSim. Finally, experiments based on a set of realistic configurations and operation runtimes are implemented in CloudSim to illustrate the effect of two reliability factors on cloud system under different resource scheduling algorithms.
