Mistake 1: Optimizing without ownership
If nobody owns a resource, nobody deletes it. Tagging and ownership are the foundation of cost control.
Mistake 2: Buying commitments too early
Savings Plans and Reserved Instances can reduce cost, but they can also lock you into bad decisions.
Mistake 3: Ignoring hidden costs
Many AWS bills are inflated by costs teams do not watch closely.
- NAT Gateway traffic
- Data transfer
- CloudWatch logs
- Old snapshots
- Idle load balancers
- Overprovisioned RDS
Mistake 4: No recurring FinOps process
Cost optimization is a habit. Without monthly reviews and alerts, waste always returns.
