Automated Cloud Provisioning on AWS using Deep Reinforcement Learning

As the use of cloud computing continues to rise, controlling cost becomes increasingly important. Yet there is evidence that 30% 45% of cloud spend is wasted (Weins 2017). Existing tools for cloud provisioning typically rely on highly trained human experts to specify what to monitor, thresholds for triggering action, and actions. In this paper we explore the use of reinforcement learning (RL) to acquire policies to balance performance and spend, allowing humans to specify what they want as opposed to how to do it, minimizing the need for cloud expertise. Empirical results with tabular, deep, and dueling double deep Q-learning with the CloudSim (Calheiros et al. 2011) simulator show the utility of RL and the relative merits of the approaches. We also demonstrate effective policy transfer learning from an extremely simple simulator to CloudSim, with the next step being transfer from CloudSim to an Amazon Web Services physical environment.
