Continuing on from the previous episode, we look at creating a Docker Swarm cluster and using Traefik to load balance and route requests to various applications. Using this and CloudFlare proxies, we're able to create and deploy hobby applications in minutes.

We also look at structuring our application top support multiple databases; each containing their own schema.
