Automate MAP Tagging at Scale with Amazon Nova and AWS Serverless

This article presents a serverless solution using Amazon Nova and AWS services to automate AWS Migration Acceleration Program (MAP) tagging at scale, enabling organizations to generate correct tag values and remediation commands in minutes.

• Deploys via single CloudFormation template in 5–8 minutes with Amazon Bedrock (Nova Pro), Lambda, Cognito, and AWS Config
• Two-phase architecture: AI extraction of parameters followed by deterministic rule-engine tag generation to prevent hallucination
• Supports Wizard Mode (instant, no AI calls) and Conversational Mode (natural-language assistance) for tag generation
• Generates AWS CLI and Terraform commands for 55+ MAP-eligible services across 9 tag value patterns
• Discovers untagged resources via AWS Config with same-account and cross-account scanning support
• Implements security controls: Cognito authentication, API Gateway rate limiting, KMS encryption, HTTPS enforcement, and least-privilege IAM roles
• Includes governance artifacts (SCP, Tag Policy, Scanner Role Template) for compliance and multi-account deployments

The solution eliminates manual MAP tagging errors while maintaining enterprise security and compliance requirements for migration programs.
