Abstract (in Japanese) (See Japanese page) 
(in English) Cloud computing and its associated virtualization have already been the most vital architectures in the current computer system design. Due to the popularity and progress of cloud computing in different organizations, performance evaluation of cloud computing is of particular importance, which can help computer designers make plans of the system capacity. In this paper, we aim to evaluate the performance of a cloud datacenter, called Bitbrains, by using queueing models only from CPU utilization data. More precisely, a simple queueing model is provided to represent the task processing of each virtual machine (VM) of the cloud, where the input stream is supposed to follow a non-homogeneous Poisson process (NHPP). Then, the parameters of arrival streams for each VM in the cloud are estimated. Furthermore, the superposition of estimated arrivals is applied to represent the CPU behavior of an integrated virtual platform. Finally, the performance of the integrated virtual platform is evaluated based on the superposition of the estimations.
