Finance wants automatic alerts when daily spend deviates unusually from normal patterns — not just when a budget threshold is crossed. Which feature does this?
A.AWS Budgets
Budgets alert on fixed thresholds — not ML-detected anomalies.
B.AWS Cost Anomaly Detection
Correct — ML-based anomaly alerting on spend.
C.AWS Cost Explorer forecasts
Forecasts project future spend but don't flag anomalies.
D.Billing alerts on CloudWatch
Billing alarms are static threshold alarms, not pattern-based detection.
Why this answer
Cost Anomaly Detection uses ML to learn your spend patterns and alerts on unusual changes — catching spend spikes that don't cross fixed budget thresholds.
