Part 2: Amazon Bedrock cost attribution with Amazon Athena and CUDOS

This article demonstrates how to analyze Amazon Bedrock costs using Cost and Usage Reports (CUR 2.0) with IAM principal attribution, Amazon Athena queries, and CUDOS dashboards.

• Set up CUR 2.0 with caller identity (IAM principal) allocation data enabled to populate line_item_iam_principal column
• Query CUR data in Athena to break down Bedrock costs by IAM principal, usage type, and custom tags
• Use dynamic tag discovery with UNNEST to explore unknown tag schemas across IAM principals
• Compare costs across multiple services and applications using IAM role-based filtering
• CUDOS version 5.8 provides pre-built Bedrock dashboards with flexible grouping, cost-per-million-tokens tracking, and interactive drill-down filtering
• Athena queries cost approximately $0.00005 per query with partition projection on billing_period

Organizations can now track Bedrock adoption and costs at granular levels to inform cost allocation decisions and optimize model selection across teams and projects.
