| ❌ Don't | ✅ Do |
|---|---|
| Over-provision "just in case" | Right-size based on metrics, scale up if needed |
| Use On-Demand for steady workloads | Use Reserved/Committed for predictable usage |
| Store all data in hot tier | Implement lifecycle policies |
| Skip tagging | Tag everything for cost visibility |
| Review costs monthly | Review weekly, alert on anomalies |
| Provider | Tools |
|---|---|
| AWS | Cost Explorer, Cost Anomaly Detection, Compute Optimizer |
| Azure | Cost Management, Advisor |
| GCP | Cost Management, Recommender |
