Docker Swarm mode allows for automatic load balancing in the Docker environment, as well as scripting for writing and structuring the Swarm environment. It also allows you to easily roll back environments to a previous state.
Above all, Docker Swarm emphasizes high-security features. It improves connectivity between the Swarm's worker and manager nodes while increasing stability with the use of load balancing. In general, load balancing ensures that the Swarm environment becomes easily scalable.
The Docker CLI's direct integration with Docker Swarm eliminates the need for external orchestration software. For the development and handling of a swarm of Docker containers, you don't need to use any other tool.
