Migration of NCSOFT Game Servers to Kubernetes
summary
Migration moves 16 stateless web/API services from VMs into an OpenStack-backed Kubernetes cluster using OpenStack + Kubernetes + Docker, cutting VM count from 52 to 8 and enabling dozens of rolling updates per day. Networking starts with flannel then switches to host-gw networking and MTU tuning for better throughput. Logging uses Fluentd per‑pod with emptyDir volumes shipping to Elasticsearch. Monitoring combines Zabbix, Prometheus and Grafana; autoscaling ties into OpenStack and the team prepares a new fully containerized mobile game for hybrid clouds (AWS/GCP).
