云计算下基于容错QoS的虚拟机资源分配策略
Virtual Machine Resource Allocation Strategies Based on Fault-tolerant QoS in Cloud Computing
-
摘要: 为了提高云环境下虚拟机的可靠性及执行用户请求的成功率,采用了基于cloudsim的开源框架构建了云计算平台,提出了基于容错QoS、随机分配及按序分配三种资源分配策略,并对提出的三种策略进行了对比.实验结果表明,基于容错QoS的虚拟机资源分配策略有性能上的优势.Abstract: In order to improve the reliability of virtual machines and the success rate of user's requests in cloud environment, this paper proposes to build the cloud computing platform based on the open source framework cloudsim.Three strategies including fault-tolerant QoS, randomly allocation and sequentially allocation are presented and compared.Empirical results show that the resource allocation policy of fault-tolerant QoS outperforms the other policies.
