The finance team needs near-real-time dashboards (with hourly granularity) showing cost trends across multiple AWS accounts in an Organization. What is the most operationally efficient solution to provide detailed cost metrics and dashboards?

The AWS Cost and Usage Report (CUR) provides the most granular and comprehensive cost and usage data, including resource-level details, which is essential for detailed cost trend analysis. Delivering it to Amazon S3 allows for long-term storage and cost-effective querying. Amazon Athena can then efficiently query this large dataset directly from S3, and Amazon QuickSight is a powerful business intelligence service for creating interactive dashboards. This combination offers a scalable, automated, and operationally efficient solution for near-real-time cost visibility across multiple accounts. Building CloudWatch dashboards with Insights and Cost Explorer data is less ideal because CloudWatch Insights is primarily for log analysis, and while Cost Explorer provides aggregated data, it lacks the raw granularity of CUR for detailed trend analysis. Writing a daily Lambda to collect Cost Explorer data is less efficient and more complex to manage than using the native CUR delivery. Creating an IAM user for direct Cost Explorer access provides basic visibility but doesn't offer the detailed, customizable dashboards and historical trend analysis required by the finance team.
