I'm a bit confused. So you're saying instead of running 20 containers for an app that are 1-4Gi and some odd CPU I should replace them with 20 dedicated servers? By your own numbers that's 200x+ as expensive. Really 20 containers is a pretty small app considering 5 app server containers, a DB, a cache, a load balancer, some monitoring/alerting crap 2x for redundancy.
