AWS Single Architecture (Uni-President)
3 min read
This design reuses the LG H&H architecture: a Next.js frontend, FastAPI backend on ECS Fargate, AI-service integration, Neptune, and OpenSearch. Uni-President adds Glue ETL to integrate data across 5 BUs, TimeStream for cold-chain measurements, and OPENPOINT member relationships in a Neptune graph estimated at 900K edges.
