Keynote: Red Hat: Making Containers Boring (again)
summary
Red Hat describes making Kubernetes deliberately boring by running very large, dense hosted clusters (notably OpenShift Online Starter) and using Prometheus to find real failures. Concrete fixes include deduplicating noisy events, cutting memory use from cluster components to about one third, eliminating repeated secret fetches that once pulled 800 MB per server startup, and handling a user-triggered burst that created ~40 pods/sec. These changes reduce CPU and API latency and improve migration and scale.
