I find it highly entertaining a two-year old company who was founded on the basis of helping slash cloud spending found so much waste in their own AWS spend. This is not an example of dogfooding, but an example of sheer incompetency and massive technical debt.
I'd really like to start seeing a series of blog posts from companies who are running extremely lean and efficient tech environments by utilizing cloud in an intelligent manner and avoiding the expensive and unnecessary bullshit that's so prevalent today. The ones that can brag "How we run a $4M/yr SaaS on $40k/yr of AWS spend!" are far more interesting than "How we stopped incinerating millions of VC money by simply turning off shit we didn't need"
