Technically, it’s not much different from using Ansible to run Docker on remote hosts. What it provides is a set of conventions based on what most web apps look like. Eg. built-in proxy with automatic TLS and zero downtime deployments, first-class support for a DB and cache, encrypted secrets, etc. It’s definitely not for every use case, but for your typical 3-tier monolith on a handful of servers I found it does the job well.
