Replacing a $3000/mo Heroku bill with a $55/mo server

I'd like to nit-pick a little about the title.

They replaced a $500/mo bill with a $55/mo server. And at the same time increased what they could do before - run 5 extra staging environments!

While saving $445/mo isn't nothing, in my book enabling teams to freely run the staging environments they need is the real win here! Limiting testing resources can be a real drag on momentum in a project!

And they're now running all environments on a single machine! The bigger blast radius the better, right? Right...?
