With the rise of cloud computing services, the definition of cloud computing, service quality measurement and evaluation of consistency have caused the attention of major cloud service providers and cloud computing users. Therefore, it is imperative to study the evaluation methods and index system of cloud computing service quality and evaluate service quality, so as to provide data support and decision-making basis for evaluating the service level of cloud computing. In order to solve the problem of lack of cloud computing service quality evaluation method and evaluation index system, based on the grasp of the existing domestic cloud computing service quality evaluation and basic solutions and its applications, the cloud computing method of service quality evaluation index is studied from its mature models and ideas. In this paper, we build cloud computing service quality evaluation index system,extract cloud computing service quality evaluation requirements, and enable cloud computing service quality evaluation to be truly used.
