I just run Go servers under fcgi. You get orchestration and crash recovery with a very simple interface. Fcgi will launch server processes as needed, feed them events, and shut it down when there's no traffic. Performance is good, and you can run on cheap hosting.
Which hosting do you use? I use fastcgi with python on Dreamhost and it works fine, but I’m sorta worried that they’ll turn it off because it seems kind of niche and under-documented
