Enterprise-grade three-tier architecture spanning two Azure availability zones with perimeter security, application, and data tiers. Traffic flows from users through Front Door CDN and WAF Policy to Application Gateway, then through Azure Firewall to VMs and AKS node pools distributed across AZ1 and AZ2. PostgreSQL primary-standby replication, Azure Cache for Redis, and Blob Storage provide resilient data layer services monitored by Azure Monitor, Application Insights, and Log Analytics. Azure DevOps and GitHub drive CI/CD pipelines deploying containerized workloads via Container Registry to AKS clusters, with Key Vault securing credentials and Managed Identity enabling secure service authentication.
