Docker Swarm turns a group of Docker hosts into a single cluster managed through the standard Docker API. It uses Raft consensus for manager HA, overlay networks for cross-host communication, and a routing mesh that load-balances published ports on every node — no separate load balancer needed for simple deployments.
