Docker Swarm

Docker Swarm is a container orchestration tool that enables the management and deployment of a cluster of Docker hosts. It allows users to define the desired state of their applications and services, and then automatically deploys and manages them across the entire cluster.

With Docker Swarm, users can create a cluster of Docker hosts, which can be either physical machines or virtual machines, and then deploy containers across the entire cluster. It provides a unified API for managing the Docker hosts and the containers, and it can automatically manage the scaling and load balancing of the containers based on the available resources and user-defined rules.

Docker Swarm also includes built-in support for secure networking and storage, as well as integration with Docker Hub and other container registries. It can be deployed on-premises or in the cloud, and it is widely used for deploying and managing containerized applications at scale.
