I’m most concerned that the design mixes two serving paths without a clear ownership boundary: ALB to EC2 app servers for the web app, and API Gateway/Lambda for mobile plus MCP/LLM access. In production this can create duplicated auth, rate limiting, observability, and business logic, especially if both paths call Bedrock or the RDS database differently.
