AWS Cost Anomaly Detection

AWS Cost Management feature that uses machine learning to detect unusual spend and alert owners.

Definition

Cost Anomaly Detection creates monitors by service, account, cost category or tag, learns normal spending patterns and sends alerts with root cause analysis when anomalies occur, reducing billing surprises.

Example

An alert identifies a sudden $2,000-per-day increase in NAT gateway data processing in one account.

Exam tip

Anomaly detection catches unexpected spikes without manual thresholds, unlike fixed AWS Budgets alerts.
