As for the virtual machine placement problem in multi-resource cloud computing environment,a dynamic scheduling algorithm called MIUS(maximize integrated utilization scheduling),was proposed,basing on stochastic model with high-integrated utilization.First,a virtual central queue was created to cache user tasks in scheduling center,and then,for executing tasks,stochastic routing algorithm was utilized to make a quick selection from servers,finally virtual waiting queues were created on selected servers to store arrival tasks and MIUS was used for VM's provision.Simulation results show that MIUS is able to achieve a load balance and greatly improve the integrated utilization of cloud data center with guaranteeing QoS.
