| 摘 要： | 云计算提供了4种部署模型:公有云、私有云、社区云和混合云.通常,一个私有云中可用的资源是有限的,因此云用户不得不从公有云租用资源.这意味着云用户将会产生额外的费用.越来越多的企业选择混合云来部署它们的应用.在混合云中,为了实现用户的利益最大化,必须满足使用资源的费用最小化和用户的QoS,为此为混合云用户提供了一个既能最小化资源费用又能保证满足QoS的资源分配方法.实验结果表明,该算法在保持低操作成本的同时还满足了用户的QoS.

| Abstract: | Cloud computing provides four deployment models:public cloud,private cloud,community cloud and hybrid cloud.Generally,resources available in a private cloud are limited,thus the cloud users have to rent resources from public clouds.This requirement means that cloud users will incur extra costs.More and more enterprises choose the hybrid cloud to deploy their applications.In the hybrid cloud,in order to minimize the cost of using resources,it is also important to satisfy QoS for user.Therefore,this paper proposed resources allocation algorithm for hybrid cloud users who want to minimize the resource cost and ensure QoS satisfaction.The empirical results demonstrate that resources can be allocated by our algorithm in a way that satisfies the user QoS and keeps low operational costs. |
