One-line summary
Set cost, usage, Savings Plans, or RI targets and notify stakeholders when actual or forecast values cross thresholds.
Exam focus and pitfalls
- Budgets supports actual and forecast thresholds, filters, email or SNS notifications, and controlled budget actions.
- A budget does not stop overspending resources by default.
- Budgets compares against a target; anomaly detection finds unusual patterns; Cost Explorer supports analysis.
Key takeaway
A defined target plus actual or forecast threshold alerts means AWS Budgets.
Actual and forecast alerts
- A zero spend budget detects unexpected charges as soon as spending begins.
- A monthly cost budget can alert on both actual and forecast spending.
- One budget may use several thresholds, such as actual 85%, actual 100%, and forecast 100%.
- A budget alert does not stop resources by default; production Budgets Actions need least privilege, approval, and rollback.
