Answer
Container-level scaling means more replicas on same node; node-level scaling distributes containers across nodes.
Quick Answer
Container scaling adds more container instances on the same node — uses more CPU/RAM on that host. Node scaling adds more physical or virtual machines to the cluster. Container scaling is fast (seconds); node scaling is slower (minutes). Orchestrators like Kubernetes do both automatically based on load.
