Nowadays, most researchers carry out such unilateral research on virtual machine scheduling strategy, energy consumption. And there are few jobs which less concern about the impact of multiple factors. Due to heterogeneous cloud environment is made up of thousands of resource nodes. The resource utilization, virtual machine scheduling and other indicators must be related with uncertainties arising from node failure events. The paper studies the virtual machine scheduling strategy under the supply of reliable resources. And a dynamic-reliable resource supply FR strategy is proposed. In this paper, the Cloud Sim simulation cloud platform was used to simulate the experiment and compare with classical IQR/LR scheduling algorithm during simulation experiment. And experimental results show that FR strategy can effectively improve CPU utilization and is conducive to data center energy consumption reduction.
