About This Architecture

Multi-region Azure subscription architecture for WEX Research and Innovation with dual availability zones, hybrid connectivity via VPN Gateway and ExpressRoute, and layered security through Azure Firewall and Network Security Groups. Traffic flows from the corporate network through WEX Firewall and VPN Gateway to Azure Firewall, then routes to API Management (Internal) which distributes requests across App Service Plans, Container Apps, and AKS Clusters in both AZ-1 and AZ-2. Data tier spans Azure SQL with geo-replication, Cosmos DB with replicas, and Storage Accounts across both zones, with Private Link securing backend connectivity and Key Vault managing secrets. This architecture demonstrates enterprise-grade isolation, disaster recovery, and compliance for regulated research workloads. Fork and customize this diagram on Diagrams.so to match your subscription topology, add additional subnets, or adjust NSG rules for your team's access patterns. The design prioritizes zero-trust principles with Azure AD integration, Azure Policy enforcement, and comprehensive monitoring via Log Analytics and Azure Monitor.
