摘要
运用云计算模型与马尔可夫过程理论,建立云计算下的负载转移,给出转移概率算法来解决节点的负载失衡问题。通过将服务封装在虚拟机中并映射到各台物理服务器上,根据虚拟化技术负载变化进行虚拟机和物理资源的重映射,从而实现整个系统的负载均衡。
System virtualization provides an effective way for resource management in cloud computing.By encapsulating services in virtual machines（VMS） which are finally mapped to physical servers,virtualization can do VM remapping according to workload.Therefore,in this paper,Load transfer model of cloud computing is built by cloud computing model and MarKov process theory and details data analyzing are provided,and finally,this paper presents transfer probability arithmetic to solve the problem of load unbalance.Researchers of related topic can gain useful information about the cloud computing.
