Why each option
A node in a Docker Swarm is fundamentally an instance of the Docker Engine that actively participates in the swarm cluster.
A node in a Docker Swarm is indeed a Docker Engine instance that has been initialized or joined to the swarm. These nodes can operate either as manager nodes, which handle swarm management tasks, or worker nodes, which run application services.
