A VM/VPS running Ubuntu with one GB of RAM to be precise. Had to recreate a droplet when testing it because I only provisioned 512 MB of RAM.
So far, it has done its job quite nicely. Just make sure you don't plan on installing it next to a webserver. Its installer hijacks port 80/443 with its own nginx webserver.
