Virtual Machine Deployment And Migration Strategy Based On Cloud Computing Platform

Cloud computing platform is a complex large-scale network system,and its presence has changed the existing network delivery model.The foundation of the cloud computing platform is virtualization,virtualize the physical resources of the cloud computing platform into a resource pool through virtualization technology,and then provide the resources as a service to the users through resource scheduling.With the increasing scale of the cloud computing platform,the virtual machine Of the rapid deployment and dynamic migration strategy to become the core of the cloud computing platform.Because the cloud computing platform is complex and needs to meet the requirements of large-scale deployment and dynamic change of resource requirements,the efficient deployment of virtual machines is facing great challenges.Therefore,efficient virtual machine deployment and migration strategy are very important applicationsAiming at the deployment of large-scale virtual machine cluster,The paper puts forward the strategy of virtual machine deployment.In order to improve the virtual machine deployment time under the cloud computing platform,the virtual machine image preprocessing strategy and the distributed storage popular image are designed to make the virtual machine deployment time greatly reduced.In this paper,the virtual machine cluster deployment node is selected according to the system resource availability,and the resource utilization rate of the cloud computing platform is improved by the deployment of the optimal resource available service node.For the problem of high dynamic energy consumption,the paper proposes a double threshold migration triggering strategy,which integrates the current system service node load and determines whether the virtual machine migration needs to be carried out by the next threshold judgment.The stability of the system reduces the interference of the burst to the migration threshold.The migration policy also optimizes the selection of the migration virtual machine and the service node selection of the migration virtual machine to be deployed.At the end of this paper,the overall framework of cloud computing platform,the key process of virtual machine cluster deployment and the key process of virtual machine dynamic migration are described in detail.Finally,the performance and efficiency of the improved algorithm are verified on the experimental platform.
