How you inform your backup system where to get backups ? How you set pg_hba and other configs? Few other "how?" and you're doing what you'd be doing on VM anyway

Simple answer: with configuration. In Docker Compose or Kubernetes. Less often in Mesos. Maybe I want to run it on a fleet of VMs, maybe on bare metal.

Right. But with containers I can have different apps using different dependency versions. Some things use nginx, some use some other web server. Some things run with node 12, some with node 16, some things use MySQL, some other things need Postgres. This is so easy with containers.
