Learnings from the Enterprise-level Kubernetes transformation at Elkjøp Nordic

on YouTube ↗01h 02m

" summary

Elkjøp migrates 200+ microservices from Azure App Service to AKS, replacing 70→200 app services and cutting hosting cost from ~3M NOK/yr to ~1M NOK/yr while keeping systems live. Platform uses GitOps (Flux) & sealed-secrets for bootstrapping and disaster recovery, injects Linkerd service mesh for mTLS and metrics, relies on Prometheus/Grafana plus KEDA and Promitor for autoscaling, validates with k6, and rebuilds recovery so clusters can be reprovisioned and functional in about 20 minutes, driving faster troubleshooting and measurable quality gains.
