What is Docker Swarm? | Definition from TechTarget

▤ Summary

With Swarm, IT administrators and developers can establish and manage a cluster of Docker nodes as a single virtual system. Docker Swarm lets developers join multiple physical or virtual machines into a cluster. It creates a cooperative group of systems that provide redundancy, enabling Docker Swarm failover if one or more nodes experience an outage. A Docker Swarm cluster also enables administrators and developers to add or subtract container iterations as computing demands change. Such orchestration ensures containers are only launched on systems with adequate resources to maintain necessary performance and efficiency levels for containerized application workloads.
