摘要 提出了一种基于弹性云的负载均衡方法.这一方法构造了负载均衡模型框架,建立了模型对于虚拟机负载状况和虚拟机集群资源利用率进行量化评估,为实现任务的分发和虚拟机集群的弹性伸缩,设计了任务调度算法和弹性伸缩算法.实验结果表明基于弹性云的负载均衡方法在实现负载均衡的同时,有效提高了资源利用率. A load balancing method based on elastic cloud computing is proposed.The method introduces the framework using a load balancing method and the model to evaluate load status of the virtual machines and resource utilization of the virtual machine cluster.And the method implements the distribution of the tasks and elastic virtual machine cluster via task distribution algorithm and elastic expansion algorithm.The simulation shows that this method improves the resource utilization effectively while implementing the load balancing.
