Managing a Million Kubernetes Clusters
summary
Azure Kubernetes Service runs and troubleshoots a million clusters by adding telemetry, automated detection and remediation, and tighter guardrails rather than hiring a proportional ops team. Key tactics include deploying Prometheus per control plane for near‑real‑time metrics, surfacing a single pane of glass for cluster health, and running detectors and remediators that catch common failures like s‑net port exhaustion, image‑pull blocks or OOM storms. Support traffic is dominated by >50% workload errors, so automated fixes and opinionated managed modes reduce outages.
