Answer
All state lives in etcd; API servers scale horizontally without syncing state.
Quick Answer
kube-apiserver stores no persistent state itself — all state is in etcd. This makes API server stateless and horizontally scalable. Run 3 or more API server replicas behind a load balancer and the cluster handles API server failures transparently. Losing one API server instance doesn't lose any data or interrupt running workloads.
