Docker Swarm
Docker Swarm is a container orchestration tool, meaning it helps manage multiple containers running across a cluster of machines. Think of it as a conductor for an orchestra of software containers, ensuring they all work together harmoniously. It allows developers and system administrators to deploy, manage, and scale applications built with Docker containers. At its core, Docker Swarm turns a pool of Docker hosts into a single, virtual Docker host, simplifying the management of complex, multi-container applications.
