Why AWS Cost and Usage Reports?
The AWS Cost and Usage Reports (CUR) contains the most comprehensive set of cost and usage data available. You can use Cost and Usage Reports to export your cost and usage data to an Amazon S3 bucket that you own. You can receive exports that break down your costs by the hour, day, or month, by product or product resource, or by tags that you define yourself. AWS delivers the export to your bucket at least once a day as either a CSV or Parquet file. You can process the export using analytics tools, such as Amazon Athena or Amazon Redshift, or spreadsheet applications, such as Microsoft Excel. You can also create visualizations of your CUR using business intelligence tools, such as Amazon QuickSight, to share insights with your teams.
