Performance vector-based algorithm for virtual machine deployment in infrastructure clouds

Regarding the virtual machine deployment issues in cloud computing,the Performance Matching-Load Balancing(PM-LB) algorithm of virtual machine deployment was proposed.With performance vector,the performance standardization of virtual infrastructure was described.The matching vector was obtained by calculating the relative vector distance of virtual machine and the servers,then a comprehensive analysis of matching vector and load balancing vector was done to get the deployment result.The results of simulation in CloudSim environment prove that using the proposed algorithm can obtain better load-balancing performance and higher resource utilization.
