A company runs its applications on Amazon EC2 instances. The company performs periodic financial assessments of its AWS costs. The company recently identified unusual spending. The company needs a solution to prevent unusual spending. The solution must monitor costs and notify responsible stakeholders in the event of unusual spending. Which solution will meet these requirements?

A
Use an AWS Budgets template to create a zero spend budget.
B
Create an AWS Cost Anomaly Detection monitor in the AWS Billing and Cost Management console.
C
Create AWS Pricing Calculator estimates for the current running workload pricing details.
D
Use Amazon CloudWatch to monitor costs and to identify unusual spending.

Explanation
Correct Answer: B - Create an AWS Cost Anomaly Detection monitor in the AWS Billing and Cost Management console.
AWS Cost Anomaly Detection is specifically designed to address the requirements described in the question:
Why Option B is Correct:
- Automated Anomaly Detection: AWS Cost Anomaly Detection uses machine learning to automatically detect unusual spending patterns without requiring manual threshold setting.
- Real-time Monitoring: It continuously monitors AWS costs and identifies anomalies as they occur.
- Notification System: It can notify responsible stakeholders via Amazon SNS when anomalies are detected.
- Proactive Prevention: By alerting stakeholders early, it helps prevent further unusual spending before it escalates.
- Integration with AWS Billing: It's natively integrated with AWS billing data, providing accurate cost monitoring.
Why Other Options Are Incorrect:
A. Use an AWS Budgets template to create a zero spend budget.
- AWS Budgets is good for setting spending limits and alerts, but it requires manual threshold setting.
- A "zero spend budget" would alert for any spending, not specifically for "unusual" spending patterns.
- It doesn't use machine learning to detect anomalies in spending patterns.
C. Create AWS Pricing Calculator estimates for the current running workload pricing details.
- AWS Pricing Calculator is for estimating costs before deployment, not for monitoring actual spending.
- It doesn't provide real-time monitoring or anomaly detection capabilities.
- It cannot notify stakeholders about unusual spending.
D. Use Amazon CloudWatch to monitor costs and to identify unusual spending.
- While CloudWatch can monitor some billing metrics, it's not specialized for cost anomaly detection.
- It would require complex custom metric creation and threshold setting.
- AWS Cost Anomaly Detection is specifically built for this purpose and provides more sophisticated ML-based detection.
Key AWS Services for Cost Management:
- AWS Cost Anomaly Detection: Best for automated detection of unusual spending patterns
- AWS Budgets: Best for setting spending limits and alerts based on thresholds
- AWS Cost Explorer: Best for analyzing and visualizing historical cost data
- AWS Billing Conductor: Best for customizing billing reports and chargeback
For the specific requirement of "monitoring costs and notifying responsible stakeholders in the event of unusual spending," AWS Cost Anomaly Detection is the most appropriate solution as it provides automated, ML-powered anomaly detection with built-in notification capabilities.
