On my last job, the company was using NewRelic (for two environments we was using at the time) which had an ok cost and "suddenly" we'd been forced to use Datadog which costs way over for our budget and after the person responsible for the change and integration see the estimated high costs, started to cut everything possible to keep it low. So, our tools degraded and we wasn't able to test things on staging and collect metrics like we was when using NewRelic. FinOps is certainly a good approach, but we need it from the start!
Haha appears some managers change only the address but the behavior is the same, I already worked on a place where we had to use free heroku addons besides the paid PostgreSQL and the dynos
