QoS约束的云经济资源管理模型研究

Research on Cloud Economic Resource Management Model with QoS Constrains

提供用户满意的、具有QoS约束的云计算应用是云计算面临的一大难题。提出了以商品市场为原型的云计算经济资源管理模型,其通过云用户与供应商的SLA协商,实现应用服务层QoS到资源设备层QoS的映射,最后利用效用函数的管理策略实现资源的优化调度。

It is a major challenge for the cloud computing system to provide satisfied cloud application with QoS constraints.We proposed a cloud computing economic management model based on commodity market prototype,which implements the mapping from application service layer QoS to resource device layer QoS over the SLA negotiations between the users and providers in cloud computing market.Finally,the utility function as management strategy was used to optimize resource scheduling.
