人们对使用经典控制理论来管理计算系统产生了浓厚的兴趣。然而，经典控制侧重于调节平衡点附近的系统状态，目前尚不清楚这种基于平衡的方法是否非常适合在面对大而快速的输入波动时提供性能保证的系统。对于云计算应用程序来说可能就是这种情况，其中消费者工作负载以快速且不可预测的方式变化。作为经典方法的替代方案，本文讨论了云计算应用中功率控制和响应时间管理的被动框架。本文提出，被动性概念提供了一种去中心化方法，用于验证互连云计算系统的集合是否能够以稳定的方式协调其行为。
There has been great interest in using classical control theory to manage computing systems. Classical control, however, focuses on regulating a system’s state in a neighborhood of an equilibrium point and it is unclear if such equilibrium-based methods are well-suited for systems providing performance guarantees in the face of large and rapid input fluctuations. This may be the case for cloud computing applications where consumer workloads vary in a rapid and unpredictable manner. As an alternative to classical methods, this paper discusses a passivity framework for power control and responsetime management in cloud computing applications. This paper suggests that passivity concepts provide a decentralized method for certifying whether a collection of interconnected cloud computing systems can coordinate their actions in a stable manner.
