Energy Efficiency of N:1 Protection Setups with Kubernetes Horizontal Pod Autoscaler
Benoit Lemoine · 2022
Kubernetes Horizontal Pod Autoscaler (HPA) permits to enhance the Power Usage Effectiveness of Data Centers. However, critical workflows like the 5G User Plane elements require some Nominal:Backup Protection schemes that are not well adapted to Kubernetes HPA. We propose an Energy Efficiency framework for comparing two different ways to setup an Horizontal Pod Autoscaler for a N:1 protected Virtual Network Function. We provide an analytic formulation, decision curves for engineers, as well as experimental results.
