CPU at 2% isn't idle. It's waiting. An RDS waiting for a query costs the same as one under load. AWS bills the instance, not the work. Wrong metric. #FinOps
Nobody owns the off-switch for your staging ECS service after 6pm.
Not the dev who last deployed it. Not the lead. Not the on-call.
It just runs. All night. #FinOps
CPU at 2% doesn't mean idle. It means the engineer stepped out. The instance is still running. AWS is still billing. The work stopped - the cost didn't. #FinOps
Closed your laptop Friday at 6.
Your EC2 dev box didn't get the memo.
It's been running since. Billing by the hour. All weekend.
Activity-driven pause: it stops when you do. #FinOps
Your staging RDS ran all weekend. Nobody touched it. You paid for 48 hours of nothing.
That's not a cloud problem. That's a scheduling problem. #FinOps
