论文摘要
在云环境中，在能源消耗方面，云服务提供商（CSP）有效地操纵了数据中心。因此，将工作量迁移到云可能会导致较低的能耗。本文表明，具有最佳云实例选择的提升和换档迁移可以提供大量的能源节省，并解释从中节省了多少和何处。此外，当部署自动缩放时，对能源消耗的变化进行了分析，表明即使没有重构应用程序，也可以预期节省更多能源。所有结论和分析均基于Cloudamize Inc.从2016年5月至2016年8月收集的实际数据，其中大约300个数据中心超过40,000台机器。
In the cloud environment, data centers are efficiently manipulated by cloud service providers (CSPs) in terms of energy consumption. Consequently, migrating workloads to clouds can result in lower energy consumption. This paper demonstrates that the Lift-and-Shift migration with optimal selections of cloud instances can provide significant energy savings, and explains how much and where the energy savings are obtained from. Additionally, the analysis on the variation of energy consumption is given when Auto-Scaling is deployed showing that further energy savings are expected even without refactoring applications. All the conclusions and analyses are based on the real data collected by Cloudamize Inc. from May 2016 to August 2016 over 40,000 machines across approximately 300 data centers.
