Multi-location retail architecture connecting 42 branch stores and remote teams to a centralized AWS infrastructure in us-east-1 using Site-to-Site and Client VPN. Traffic flows through Route 53, AWS WAF, and CloudFront to an Application Load Balancer distributing requests across EC2 t3.large instances running ERP software in public subnets, with RDS PostgreSQL primary-standby replication across availability zones for high availability. The design implements defense-in-depth security with IAM, Secrets Manager, and Security Groups, while S3 handles images and documents with Glacier archival, and CloudWatch plus SNS provide operational visibility.
