Level 0 | ICC Capital Hall | Room 2

Sustainable cloud computing has been a topic for over a decade, but we lack concrete data on Kubernetes energy consumption. This session shares a case study of a microservice running on a k3s clusters, providing real energy metrics at every stage of Platform Engineering: Day 0 (manual setup with k3s, Cilium, microservice deployment), Day 1 (introducing ArgoCD, Falco for security), and Day 2 (adding observability with Prometheus, Grafana, OpenTelemetry, and Kepler). We use bare metal environments ensuring clean, measurable energy data, from idle setup to fully operational.

We’ll explore how tools like Kepler estimate energy consumption for Kubernetes components and compare them to actual plug measurements. For Day 3, we’ll present experiments: changing programming languages, OS images, VPA and KEDA. By sharing practical insights and data, we aim to inspire engineers to innovate and build a more sustainable cloud-native ecosystem.

Presented by TAG Environmental Sustainability Leads.
