Azure E-Commerce Order Lifecycle Platform demonstrates a production-grade, multi-availability-zone architecture spanning presentation, application, and data tiers within a single VNet (10.0.0.0/16). Traffic flows from mobile clients through Azure CDN and Traffic Manager to dual Application Gateways with WAF policies, then to microservices (App Services, AKS, Container Apps, Function Apps) orchestrated via Service Bus, Event Grid, and Logic Apps for notifications and order processing. Data persistence spans Azure SQL (primary/failover), Cosmos DB, PostgreSQL, MySQL, Redis Cache, Data Lake, and Storage Account, with real-time analytics via Event Hubs, Stream Analytics, and Synapse Analytics, all secured by Key Vault and monitored through Power BI dashboards. This architecture exemplifies Azure best practices for resilience, scalability, and separation of concerns across order management, payments, delivery, and customer evaluation workflows.
