Amazon Bedrock trade-offs for a document intelligence pipeline
Trade-off question: direct Converse API document extraction on Bedrock versus a refactored pipeline with Textract or Bedrock Data Automation, Step Functions, batch inference, validation, and human review.
Quick answer
Sending PDFs straight to a Bedrock model is quick and handles varied layouts, but it is costly per page, hard to audit field by field, and fails silently when the model guesses. The refactor adds structured extraction, validation rules, cheaper batch processing for backlogs, and a human-review loop, at the price of more components and weeks of work. I would ship the direct approach now with tool-use JSON schemas and validation checks, then move high-volume document types onto the refactored pipeline over two quarters based on measured field accuracy and cost.
The interview question
Your team extracts fields from contracts and invoices with Amazon Bedrock. The fast option is to send each PDF to a Bedrock model through the Converse API with a prompt and parse the reply with custom code. The slower option is a platform refactor: OCR and layout extraction with Amazon Textract or Bedrock Data Automation, Step Functions orchestration, batch inference for backlogs, schema validation, Guardrails, and human review. Compare the trade-offs and recommend a path for the next two quarters.
