Introduction to Docker Swarm

Imagine you have dozens of containerized applications running. What if they need to work together? What if one machine fails?

Managing many containers manually across multiple machines becomes a huge challenge. You need a system to orchestrate them!

Docker Swarm is Docker's native tool for container orchestration. It allows you to manage a cluster of Docker engines as a single, unified virtual Docker host.

Think of it as a conductor for your orchestra of containers, ensuring they play together harmoniously.
