Description
Deploy an AWS Step Functions state machine that iterates AWS Invoice Units via Map state, retrieves per-BU invoice summaries and PDFs, archives to Amazon S3, runs cross-BU variance analysis with Amazon Bedrock, and writes chargeback allocations to Amazon DynamoDB.
Architecture
AWS Step Functions (Map state) → AWS Lambda (list Invoice Units + fetch invoices) → Amazon S3 (PDF archive by BU) → Amazon Bedrock (cross-BU chargeback analysis) → Amazon DynamoDB (ledger) + Amazon SNS (notifications)
Deployed and Tested
Stack deploys in us-east-1. Created test Invoice Unit (TestBU), executed SFN successfully in ~30s. Bedrock generated chargeback allocation JSON. DynamoDB ledger entry confirmed. Test unit cleaned up.
