基于QoS的云计算资源分配算法

目前,基于云计算的服务越来越具有动态性,资源的分配遇到了前所未有的挑战性,我们不能简单地从成本单一方面来衡量资源分配算法的优劣。针对以上问题,提出了具有QoS限制的资源分配算法,从用户和资源提供者两个方面来考虑资源的分配,在保证用户任务的多维QoS需求的同时,寻求用户满意度和资源利用率的综合效用值的提升。通过仿真实验表明,该资源分配算法,可以减少任务之间对资源的竞争,提高所有任务的全局效用值。

Resouce Allocation Algorithm for Cloud Comupting Based on QoS

As cloud-based services become more numerous and dynamic,resource provisioning becomes more and more challenging,we can’t measure performance of the allgorithm from cost or time solely.To slove the above problem,a QoS constrained resource allocation allgorithm is considered in the paper,in which it consider from user and resource provider.This paper must guarantee QoS of every task,at the same time,seek the promotion of utility.The experiment shows that the algorithm can reduce the competition of all tasks for resource and improve the overall effectiveness of all tasks.
