Which solution will meet these requirements?
In the organization’s management account, use AWS Budgets to create a budget that has a daily period. Add an alert threshold and set the value to 80%. Use Amazon Simple Notification Service (Amazon SNS) to notify the finance team.
In the organization’s management account, set up the organizational view feature for AWS Trusted Advisor. Create an organizational view report for cost optimization. Set an alert threshold of 80%. Configure notification preferences. Add the email addresses of the finance team.
Register the organization with AWS Control Tower. Activate the optional cost control (guardrail). Set a control (guardrail) parameter of 80%. Configure control (guardrail) notification preferences. Use Amazon Simple Notification Service (Amazon SNS) to notify the finance team.
Configure the member accounts to save a daily AWS Cost and Usage Report to an Amazon S3 bucket in the organization’s management account. Use Amazon EventBridge to schedule a daily Amazon Athena query to calculate the organization’s costs. Configure Athena to send an Amazon CloudWatch alert if the total costs are more than 80% of the allocated budget. Use Amazon Simple Notification Service (Amazon SNS) to notify the finance team.
Explanations:
This option uses AWS Budgets, which is designed to track AWS costs against allocated budgets. Creating a daily budget with a threshold of 80% and using Amazon SNS for notifications directly aligns with the requirements of tracking costs and notifying the finance team effectively.
AWS Trusted Advisor does not provide budget tracking capabilities or email notifications based on budget thresholds. It offers insights for cost optimization but lacks the specific budget alert feature required in this scenario.
AWS Control Tower provides governance and best practices for managing AWS accounts but does not offer budget alerting functionalities directly. It focuses on compliance and setup rather than on monitoring and alerting for budget thresholds.
This option involves a complex setup using Cost and Usage Reports, Amazon Athena, and EventBridge. While it could theoretically work, it is unnecessarily complicated compared to option A, which directly meets the requirements with simpler configuration through AWS Budgets and SNS notifications.
I estimate that the answer is:
In the organization’s management account, use AWS Budgets to create a budget that has a daily period. Add an alert threshold and set the value to 80%. Use Amazon Simple Notification Service (Amazon SNS) to notify the finance team.
