MyEddie's current production architecture spans two AWS accounts, integrating a load-balanced application tier with SQL Server AlwaysOn availability groups and Oracle ERP via DMS replication. The DMZ layer fronts EC2 app servers in active-active configuration, while FSx provides shared file storage and a separate data warehouse supports analytics. This design demonstrates cross-account integration patterns, database replication strategies, and separation of concerns between transactional and reporting workloads. Fork this diagram to customize for your multi-system environment, adjust replication endpoints, or document your own hybrid cloud topology. The architecture showcases best practices for disaster recovery, data consistency, and SaaS integration at enterprise scale.
