在云计算环境中，计算能力、存储、平台和软件被抽象和虚拟化为各种云服务。同时，复杂的应用程序可以被描述为调用在运行时选择的服务的进程。服务质量（QoS）作为一种非功能性需求，是云服务选择的重要依据。然而，现实中复杂的网络环境和非法操作往往导致服务质量数据不可信，影响了云服务调度的准确性和可信性。提出了一种云服务QoS的可信管理方法。实验结果证明了可信管理方法的有效性。
In cloud computing environments, computing power, storage, platforms, and software are abstracted and virtualized as all kind of cloud services. Meanwhile complex applications can be described as processes invoking services selected at runtime. As a nonfunctional requirement, quality-of-service (QoS) is an important selection basis of cloud services. Nevertheless, the complex network environment and illegal operations generally result in the untrustworthy QoS data in reality, and then influence the preciseness and trustworthiness of cloud services scheduling. This paper proposes a trustworthy management approach for cloud services QoS. Results of experiments demonstrate the effectiveness of the proposed trustworthy management approach.
