Then there are people on the opposite side of the spectrum who don't even look at server costs. I have a task sitting in our backlog to optimize our instance usage which could save us over $100,000 a year. It has been constantly deprioritized in order work on feature development which is stupid because we could hire another developer to do it in a few days and then keep him to increase our feature development all while costing our company the same amount of money.
Granted, I think this is more of a case of the prisoners dilemma [0] between lower management and upper management (lower management doesn't want to work on it because it doesn't produce features that make him look good but he also does not want to propose the additional developer for it because then upper management will just tell lower management to do it without the additional developer).
