Docker Swarm Cluster

Docker Swarm is Docker's native clustering and orchestration mode that turns a pool of Docker Engine hosts into a single virtual cluster, scheduling containers as services with built-in load balancing and rolling updates. It ships built into the Docker Engine rather than as a separate install.
