A QoS Evaluation Model in the Environment of Cloud Computing

As the name implies, the quality of service（QoS） often reflects the service consumer satisfaction with the services provided by the service provider. In computer systems, particularly in the computer network system, as the providers of the computing and information services, It is necessary to consider the cloud user’s suitability in the process of different physical implementation in the same functional service when constructing the server cluster in the cloud. This paper is for the cloud, build a service quality model oriented user request and the implementation process, completed the choice for the physical implementation with the best users fit service.
