Multi-tier AWS web application architecture combines user-facing load balancing with automated regulatory data ingestion from US FDA sources. Internet Gateway routes user traffic through Application Load Balancer to Frontend EC2 (t3.medium) and Backend EC2 (t3.large) instances across public and private subnets, both connecting to RDS PostgreSQL (db.t3.medium) for persistent storage. Lambda Scraper function pulls FDA data, processes it via AWS Bedrock for AI-enhanced analysis, and writes to the shared database while Backend EC2 manages S3 Bucket storage for company assets and PDFs. CloudWatch Logs captures application telemetry from both EC2 tiers, enabling AWS architects to monitor performance, troubleshoot issues, and optimize resource allocation.
