Keynote: Your Philips Hue Light Bulbs Are Turned On By Kubernetes
summary
Philips Hue cloud migrates from Google App Engine to Google Container Engine (GKE), splitting a Play monolith into microservices and using Redis pub/sub to route commands to two backends (HTTP-polling bridges vs persistent WebSocket bridges). One EU cluster runs ~40 nodes and 120 pods at one point, now approaching 200 pods, operated by five developers. Engineering fixes include circuit breakers with Hystrix, a custom HPA using polynomial regression to predict connections, and a privileged daemonset to tune node socket limits; overall migration succeeds after fixes to logging and scaling.
