云计算资源管理系统是用于接收来自云计算用户的资源请求,并且把特定的资源封装为服务提供给资源请求者.在云计算环境下,如何为资源请求者选择合适的资源是一个值得研究的课题.文中通过对云计算下现有的资源提供策略的分析,同时根据不同云提供者提供的计算资源的成本不同的特点,综合考虑资源的计算能力、可靠性和单位成本三点因素,提出了云计算下基于CRP算法的资源提供策略.这种资源提供策略既能提供满足用户资源请求的服务,也能降低云服务提供者的运营成本,从而获得更大收益.%Resource management system for cloud computing is used for receiving resource requests of users and providing service for users by encapsulating given resources. How to provide the right resource for users is a valuable topic. By analyzing resource provisioning policies for cloud computing in current situation and combining the feature of resource that unit cost of different resource provided by different cloud provider is different, propose CRP( capacity-reliability-price) algorithms based resource provisioning policies for cloud computing. This policy not only provides good service for users, but also reduces the management cost of cloud service provider.
