@firstname.lastname@example.org @civodul Close to that. The "potential benefits" are that you don't have to manage the service nor communication, just the code performing a single function, and that the applications gets stopped when not in active use (so you don't pay). Most services also replicate your server to cope with traffic spikes. For a group of friends/chatbot with low traffic can be less money and management than a VPS.
I still prefer a VPS though.
