Abstract

Elasticity is an attractive feature of cloud computing, that enables increasing or decreasing the resources allocated to an application in order to adapt to changes in the workload. To efficiently utilize elasticity of clouds, the decisions on resource allocation need to be made algorithmically, adaptively and in real-time. The resource provisioning algorithm must also consider the performance requirements of the application as specified in the Service Level Agreement between the cloud provider and the client. In this paper, we present a reinforcement learning based algorithm that addresses the issues of slow convergence and lack of scalability in classical approaches such as Q-learning. We use the technique of adaptive tile coding and workload forecasting to ensure efficient utilization of resources. The effectiveness of the proposed method as compared to static, threshold-based and other reinforcement learning based allocation schemes is established with experiments on the Cloudsim platform.

使用强化学习的云应用程序的自动缩放资源
弹性是云计算的一个吸引人的特性,它允许增加或减少分配给应用程序的资源,以适应工作负载的变化。为了有效地利用云的弹性,需要通过算法、自适应和实时地做出资源分配决策。资源配置算法还必须考虑云提供商和客户端之间的服务水平协议中指定的应用程序的性能需求。在本文中,我们提出了一种基于强化学习的算法,该算法解决了经典方法(如Q-learning)中收敛缓慢和缺乏可扩展性的问题。我们使用自适应编码和工作量预测技术来确保资源的有效利用。通过在Cloudsim平台上的实验,验证了该方法与静态、基于阈值和其他基于强化学习的分配方案相比的有效性。
