Can't say I'm working at scale but one of my product is latency sensitive and we stripped docker because it was slowing down each request. I never really got to the bottom of it, someone linked me a bug in the interaction of docker / linux kernel (now fixed) which could have caused it, but I don't have time to waste chasing docker performance. Ours is a fairly simple setup: one postgres db per machine, one python app per machine on $cheapVPSProvider; number of instances goes up and down based on traffic (basically cloning one of the machines); a load balancer in front; data gets updated once per day and replicated; auth / subscription status data is stored in redis
