# Why Docker Swarm?
|
|
|
|
Pop quiz, hotshot.. There's a server with containers on it. Once you run enough containers, you start to loose track of compose files / data. If the host fails, all your services are unavailable. What do you do? **WHAT DO YOU DO**?[^1]

You too, action-geek, can save the day, by...
|
|
|
|
1. Enable [Docker Swarm mode](/docker-swarm/docker-swarm-mode/) (*even just on one node*)[^2]
|
|
2. Store your swarm configuration and application data in an [orderly and consistent structure](/reference/data_layout/)
|
|
3. Expose all your services consistently using [Traefik](/docker-swarm/traefik/) with optional [additional per-service authentication][tfa]
|
|
|
|
Then you can really level-up your geek-fu, by:
|
|
|
|
4. Making your Docker Swarm highly with [keepalived](/docker-swarm/keepalived/)
|
|
5. Setup [shared storage](/docker-swarm/shared-storage-ceph/) to eliminate SPOFs
|
|
6. [Backup](/recipes/duplicity/) your stuff automatically

[^1]: This was an [iconic movie](https://www.imdb.com/title/tt0111257/). It even won 2 Oscars! (*but not for the acting*)
|
|
[^2]: There are significant advantages to using Docker Swarm, even on just a single node.
