For organizations with a resold account ownership model, Cost and Usage Report (CUR) data is available in S3. This allows organizations to access the report in both comma-separated value (CSV) and parquet formats. You can read, download and copy the data from the S3 bucket, allowing extremely detailed analysis of AWS spend.
Locating the CUR S3 Bucket
The S3 bucket varies in name depending on the installation region of your Stax tenancy. It follows the format: stax-spotlight-transformed-cur-<ManagementAccountId>-<StaxInstallation>-master:
|Installation||S3 Bucket Name|
Accessing Cost and Usage Report (CUR) data in S3
- Log in to the Stax console
- Choose Organization then Accounts in the left-hand nav
- Locate the management account in the list then choose the log in button. The Log in to AWS Console dialog will appear
- Choose the role you wish to use to access AWS. The AWS Management Console will open in a new tab
- In the Services search box, type S3 then choose S3 from the displayed list
- The Amazon S3 console will be displayed
- Locate the S3 bucket with the Stax-managed CUR from the list.
- Select the bucket, then select the report format type.
You can also use the Amazon S3 API to programmatically access the files in the Stax-managed CUR files in S3.
The CUR files can be downloaded and viewed using spreadsheet software such as Microsoft Excel or Apache OpenOffice Calc. The size of an individual report can grow to more than a gigabyte (around 1 million rows) which might exceed the capacity of desktop spreadsheet applications to display. AWS may also split the report into multiple files stored in the same folder when CURs are large.

Differences between the CUR and Stax's Cost Module
When accessing AWS CUR files directly the size, level of detail, and granularity can be challenging to navigate. Stax's Cost Module helps you to interpret and understand AWS cost and usage data by categorizing costs and applying business logic to simplify consumption and help derive insights.
Integrating the Stax-Managed CUR
AWS supports configuring CUR reports data for integration with Amazon Athena, Amazon Redshift, or Amazon QuickSight. If you would like to integrate the Stax-managed CUR with one of these services, review Amazon's guidance:
- Querying Cost and Usage Reports using Amazon Athena
- Loading report data to other resources (Amazon Redshift and Amazon QuickSight)
