A trustworthy management approach for cloud services QoS data

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.
