I don't want to sound harsh, but please explain in what Universe is it appropriate to use Rails to configure servers, nginx, SSL, Sidekiq, when there is Chef (ruby), Puppet (ruby), Ansible (python/yaml), Salt (python), and Terraform (C/C++/HashiCorp), not to mention Docker (go) — that already do that incredibly well with a wide community support to pull from? To say that this example comes from a real-world Rails app, and then to proceed to describe what is effectively a very basic cloud automation — as an appropriate use of Rails Web Framework, is (IMHO) ludicrous. It completely flies in the face of the design principles you are touting. Perhaps it would help if you spent a bit of time explaining why Rails is used in such an unusual context.
