云计算允许应用程序提供商无缝地扩展服务，并使用户能够自适应地扩展使用。云供应商总是提供免费服务来吸引更多的匿名用户。本文提出了一种基于睡眠模式的云架构，在同一台服务器上提供免费服务和可选注册服务。以免费服务为第一服务，注册服务为第二可选服务，休眠状态为休假，建立了具有第二可选服务的异步多休假排队模型。构造了三维马尔可夫链，导出了排队模型的稳态分布，并估计了匿名用户的平均响应时间和系统的节能率。最后，我们提供了数值结果来研究不同性能度量之间的权衡。
Cloud computing allows application providers to seamlessly scale services and enables users to adaptively scale usage. Cloud vendors always provide a free service to appeal to more anonymous users. In this paper, we propose a sleep-mode based cloud architecture, in which a free service and an optional registration service are provided on the same server. Regarding the free service as the first service, the registration service as the second optional service and the sleep state as the vacation, we establish an asynchronous multiple-vacation queueing model with a second optional service. We construct a three-dimensional Markov chain to derive the steady-state distribution of the queueing model, and estimate the average response time of anonymous users and the energy saving rate of system. Finally, we provide numerical results to investigate the trade-off between difference performance measures.
