Which solution will meet these requirements?
Use an AWS Budgets template to create a zero spend budget.
Create an AWS Cost Anomaly Detection monitor in the AWS Billing and Cost Management console.
Create AWS Pricing Calculator estimates for the current running workload pricing details.
Use Amazon CloudWatch to monitor costs and to identify unusual spending.
Explanations:
A zero spend budget would not be practical or useful, as it would not allow for any spending and would trigger alerts for all legitimate costs incurred. This does not address the requirement of monitoring and detecting unusual spending.
AWS Cost Anomaly Detection is specifically designed to monitor and analyze spending patterns. It can automatically detect anomalies in costs and notify stakeholders when unusual spending is identified, making it the best fit for the company’s needs.
The AWS Pricing Calculator is a tool for estimating costs and not for monitoring actual spending. It does not provide real-time alerts or monitoring capabilities for unusual spending. Therefore, it does not meet the requirements of the company.
While Amazon CloudWatch can monitor various metrics and resources, it does not have built-in capabilities to monitor costs specifically or to detect anomalies in spending patterns. It is not designed for cost monitoring in the context required by the company.
