Which solution meets these requirements?
Run a query with Amazon Athena to generate the report.
Create a report in Cost Explorer and download the report.
Access the bill details from the billing dashboard and download the bill.
Modify a cost budget in AWS Budgets to alert with Amazon Simple Email Service (Amazon SES).
Explanations:
Running a query with Amazon Athena requires setting up a complex data query environment and wouldn’t provide a simple report by user directly related to AWS billing data without extra configuration (such as storing billing data in S3 for Athena to query).
Cost Explorer provides an easy way to generate and download detailed reports on AWS billing and usage. It allows filtering and categorizing costs by user, department, or other criteria, making it ideal for the management’s need to create department budgets.
The billing dashboard shows the overall AWS charges but does not offer the ability to filter costs by individual users or specific attributes such as department, which is necessary for this report. It is more suited for general viewing rather than detailed user-specific billing reports.
AWS Budgets is used for cost tracking and sending alerts when budgets are exceeded, not for generating detailed user-specific reports on billed items. It helps in monitoring and alerting but does not provide the requested data.
From my perspective, the answer is:
Create a report in Cost Explorer and download the report.
I rank that the answer is:
Create a report in Cost Explorer and download the report.
