About This Architecture

Azure multi-tier network infrastructure with DDoS Protection, Front Door, Azure Firewall, and Application Gateway + WAF securing inbound traffic across Core, Distribution, and Access layers. Traffic flows from Internet through Front Door and Azure Firewall to Application Gateway, then to Web, App, and Database subnets, each protected by dedicated NSGs and organized within vnet-prod (10.0.0.0/8). Management layer integrates Azure Monitor, Log Analytics, Key Vault, Azure AD, and Sentinel for centralized observability and security governance. This architecture demonstrates defense-in-depth with multiple security boundaries, high availability via Traffic Manager and load balancing, and compliance-ready monitoring for enterprise workloads.

Consider adding Azure Policy assignments and private endpoint configurations for enhanced network isolation.

How do I design a secure multi-tier Azure network with DDoS protection, firewalls, WAF, and NSGs for production workloads?

This diagram shows a production Azure network spanning Core, Distribution, and Access layers with DDoS Protection and Front Door at the edge, Azure Firewall and Application Gateway + WAF in the middle, and Web, App, Database, and Management subnets protected by NSGs. Each layer enforces least-privilege access via network security groups, while Azure Monitor, Log Analytics, and Sentinel provide cen
