A Feasibility Study on Sustainability-Driven Infrastructure Management in Cloud Data Centers
Joseph Roque, Lia Chauvel, Moayad Aloqaily, Burak Kantarcı · 2018
In this paper, we investigate methods of reducing CO2emissions from cloud computing data-centers by introducing a new perspective for legacy Virtual Machine (VM) management schemes. To this end, we introduce the incorporation of Power Usage Efficiency (PUE) into the existing selection policies for VM migration, and evaluate the improvement and possible overheads. We simulate a multi-cloud environment through the usage of CloudSim tools and by adopting the VM migration techniques that aim to minimize the data-centers energy consumption and, we subsequently aim at reducing the CO2emissions. The incorporation of PUE-awareness into existing VM management policies such as Static Threshold (ST) and Inter Quartile Range (IQR) provisioning, reduces the overall energy consumption by 33-36% as well as the number of host shutdowns by 76% at the expense of increased Service Level Agreement (SLA) Violations.
