Research On Virtual Machine Cluster Deployment Algorithm In Cloud Computing Platform

Cloud computing is a way of dynamic, easy to expand, providing virtualized computing resources via the Internet,it has needed to use, readily extensible, pay-per-use features. Users only put a small amount of administration work, without knowing the details of the internal cloud, with expertise and unnecessary cloud computing, Users can use the convenient resources. Therefore, the impact of various cloud computing application services are increasingly expanding immeasurable.Virtualization technology is the basis of the cloud computing, it is a technique to separate the top of the underlying physical device and the operating system software, through virtualization technology abstracts the physical resources to a virtual machine, the virtual machine is deployed to the host approach to resource management. Therefore, the virtual machine deployment strategy to become the focus of the current cloud computing research, this paper works as follows:(1) For virtual machine cluster deployment issues in cloud computing environment, this paper proposed a mass deployment algorithm of virtual machine cluser with resource constraints and traffic double. The basic idea of the algorithm is:for virtual machine cluster deployment, it is give full consideration to the CPU, memory, memory and other resource constraints between virtual machine cluster and physical host, and this paper considering communication bandwidth constraints between the virtual machine, through the resources and bandwidth quantify the composition of an undirected graph, where the vertex weights graph represents the resources right side of the figure represents the value of the bandwidth, the bandwidth resources and dual-constrained optimization problem into sub-graph graph partitioning problem by minimum cut algorithm to obtain the approximate solution of the problem.(2) This paper studied the cloud computing simulation platform Cloudsim, It was extended to achieve a virtual machine cluster deployment algorithm proposed in this paper, and Compared with the greedy algorithm, A single constraint algorithm, the experimental results show that the new algorithm improves communication bandwidth utilization of the system.
