| Abstract(in English) | Adaptive resource scaling is necessary for improving utilization in cloud systems. There is a trade-off relationship between utilization of computing resources and the control interval of them, and the optimal control interval depends on the changing behavior of arrival requests. In this report, we make the length of control interval changeable and adaptive so as not to increase the total number of reconfiguration while keeping a constant amount of the excess resources, even when a flash crowd event occurs in cloud systems. We first formulate dynamic control intervals to which changes in request arrival rate and their prediction errors are fitted. We then conducted numerical simulations with real-world arrival traces including flash crowd events. The results indicate that our proposed approach is effective for accommodating a sudden spike in request arrivals. |
