I use it for my interactive-fiction backend and to host save files for another game.

Nothing fancy, just a web server getting file and saving them. Like a KV-storage.

I have deployed it to dogital ocean on 2017. I have not TOUCHED it since then. Still running good. And I can access the Pharo GUI via the web VNC just from my browser with full access to the IDE and dev env.

The cons: I forgot how to run that docker image. If it fails I am in troubles reminding myself how to run it one more time. 6 years have passed...
