## What it is
Docker Swarm Classic is a Docker-native clustering system that turns a pool of Docker hosts into a single virtual host via an API proxy. It was Docker's first container orchestration project and has been archived in favor of Swarm mode built into the Docker Engine.

## Use cases
- cluster multiple docker hosts into one virtual host
- schedule containers across a fleet of docker engines
- manage a legacy docker swarm classic cluster
- proxy docker api calls to a pool of hosts
- learn how early container orchestration worked

## When to choose
- you maintain an existing classic swarm deployment and need its source
- you study the history of container orchestration systems
- you need a simple api-proxy-based clustering approach on old docker versions

## When to avoid
- you are starting a new container orchestration project
- you want a supported, actively developed orchestrator
- you run Docker Engine 1.12 or later and can use built-in swarm mode
- you need modern features like service reconciliation or built-in TLS rotation
