Hosting TEI Publisher - or a custom edition generated by it - does involve administration steps not everyone is able to perform. This usually includes installing Java, eXist-db and securing your installation with a proxy, as well as retrieving a certificate for SSL and registering a host name.
Using a docker compose workflow can be a cheap and viable alternative, at least for smaller editions without much traffic to expect. Our docker compose configuration comes with everything preconfigured and you don’t need to install any dependencies by hand.
