About This Architecture

Enterprise-grade Azure network with three-tier security perimeter: DDoS Protection, Azure Firewall, and Application Gateway with WAF guard inbound traffic across Core, Distribution, and Access layers. Traffic flows through VPN Gateway and Load Balancer to Web Servers (Standard_D2s_v3), App Servers (Standard_D4s_v3), and Dev Servers (Standard_B4ms) in isolated subnets (10.0.0.0/8), each protected by dedicated NSGs. Backend connectivity spans Azure SQL, Cosmos DB, and Redis Cache in a segregated DB Subnet, with Azure Bastion for secure admin access and centralized monitoring via Azure Monitor and Log Analytics. This architecture demonstrates defense-in-depth, least-privilege subnet isolation, and compliance-ready logging for production workloads.

How do I design a secure, scalable Azure network with DDoS protection, firewalls, and subnet segmentation?

This diagram shows a three-tier Azure network: the Core Layer (DDoS + Firewall + VPN Gateway) protects inbound traffic, the Distribution Layer (Application Gateway + WAF + Load Balancer) routes requests, and the Access Layer isolates Web, App, Dev, and DB subnets with dedicated NSGs. Each subnet connects to centralized monitoring (Azure Monitor, Log Analytics) and identity services (Azure AD, Key
