I was once on a project that inadvertently used ruby in some way for everything. Rails Bundler Vagrant Chef Opsworks configuration JavaScript bundling Generating PDFs Probably other things The system was basically frozen in time because too many cross-dependencies couldn't update in sync to something newer (the opsworks cookbook in chef were the worst offenders iirc). It was so bad when I started that I couldn't even get the system up and running locally. I ended up tossing hundreds of lines of random ruby code and with a few lines of docker commands had it up and running. Since then I've preferred keeping things nicely not dependent on each other whenever possible.
