云QoS映射模型及其面向服务选择的算法
A Mapping Model of Cloud QoS and its Service Selection-oriented Algorithm
摘要
Abstract
With the development of cloud computing, the QoS guaranteed service selection method becomes an important research issue in the cloud services domain, in which the mapping relationships from QoS requirements of user to cloud service resources is a key problem.In this paper , the hierarchy of deterministic QoS metrics and cloud resource type is analyzed from the following three levels, user, SaaS and IaaS.And then a mapping model from QoS requirements of user to cloud service resources is built.Based on the mapping model, a cloud service selection method which focuses on the QoS requirements of user is presented.The method combines entropy weight method with TOPSIS method.Finally, an implementation of the mapping method is given through an instance in the experiments.Experimental results show that the mapping model from QoS to resources and the service selection method based on the model has certain reference values for the operating mode of on-demand service with QoS guarantee.关键词
