Docker Swarm vs. Ubuntu 20 (Ubuntu 20.04 LTS)

Docker Swarm is Docker's native clustering and orchestration tool, enabling the management of a cluster of Docker nodes as a single virtual system. Integrated directly into the Docker Engine, it allows users to deploy, manage, and scale containerized applications seamlessly across multiple hosts. By utilizing Docker Swarm, organizations can achieve high availability, load balancing, and simplified service discovery, all while maintaining the familiar Docker interface.
