AWS Full-Stack AI Platform Architecture integrates CI/CD automation, containerized web services, and multi-agent LLM orchestration across ECS Fargate, Lambda, and Step Functions. The platform routes user requests through ALB to React frontend and FastAPI backend, which coordinate specialized agents—Audience Agent (Nova Premier), SQL Agent (Enterprise Data), and Strategies Agent (Claude 3.7 Sonnet)—for intelligent query execution. Data flows through Redshift, Aurora, DynamoDB, and S3 with session management, while AWS IAM, Secrets Manager, CloudWatch, GuardDuils, and WAF enforce security and observability across the VPC. This architecture demonstrates production-grade patterns for serverless agent coordination, polyglot data storage, and secure multi-tenant AI workloads.
