I also have 2 servers there, one virtual with FreeBSD and one root server as Linux hypervisor. I run the guests from a tmux session because I was too lazy to create any systemd job for this. The guest works like this already more reliably than an instance from more well-known providers.

Of course for larger deployments you'd have to take care of fail-over and all this, so it's not really an option unless you are up for setting this up all by yourself.
