虚拟机资源是云计算环境下的一类主要云服务资源,有效的资源调度方法对于改善负载均衡和提高资源利用率具有重要意义。针对虚拟机资源的调度问题进行分析,利用任务到达触发任务分配,当任务到达时,首先判断云服务资源池的运行状态,分为饱和与不饱和两种;然后针对当前任务请求下的云服务资源池状态,分别给出资源调度策略,并通过算例分析验证所提方法的有效性。所提虚拟机资源调度方法将有助于云服务资源池中虚拟机资源的均衡利用。
As one kind of the main resources of cloud computing, virtual resource sustains sorts of cloud services, and an effective resource scheduling mechanism helps to balance the load and improve the resource utility rate. Focusing on virtual resource of cloud, a resource scheduling mechanism to achieve load balancing was proposed. Triggered by an incoming job, the scheduler checked the instant state of resource pool first, and then took interrelated strategies.
