Automating Amazon Textract adapter lifecycle management across accounts
aws ·
This article outlines strategies for automating the lifecycle management of Amazon Textract Custom Queries adapters across multiple AWS accounts. It addresses three primary challenges: promoting trained adapters from development to production, routing documents to the correct adapter based on form versions, and implementing robust security controls. The proposed solution features a multi-stage pipeline that uses pre-classification to identify document types and retrieves specific adapter IDs from AWS Systems Manager Parameter Store, enabling zero-downtime updates without code redeployment. For cross-account promotion, organizations can choose between copying adapters via AWS Support tickets or using a centralized hub account to invoke APIs directly, each with distinct operational and cost implications. The guide emphasizes infrastructure-as-code practices using CloudFormation or Terraform and details essential security measures such as VPC endpoints, KMS encryption, least-privilege IAM policies, and ML opt-out configurations for sensitive data.
