description

Azure Networking Services including Virtual Networks, Private Endpoints, Load Balancers, Application Gateway, Front Door, and DNS. Covers hub-spoke topology, private endpoint patterns, and network security layers. USE FOR: virtual network setup, private endpoint configuration, hub-spoke topology, VNet peering, network security groups, Azure firewall rules, load balancer setup, Application Gateway configuration, Azure Front Door, private link setup, DNS configuration, network isolation DO NOT USE FOR: compute resource configuration (use azure-create-app), Azure Functions networking (use azure-functions), database networking within postgres/cosmos (use respective skills), cost analysis (use azure-cost-optimization), resource deployment (use azure-deploy)

Azure Networking Services

Services

Service	Use When	MCP Tools	CLI
Virtual Network	Private networking, subnets	-	az network vnet
Private Endpoints	Private PaaS access	-	az network private-endpoint
Load Balancer	Layer 4 load balancing	-	az network lb
Application Gateway	Layer 7 load balancing, WAF	-	az network application-gateway
Front Door	Global load balancing, CDN	-	az afd
DNS	Domain name resolution	-	az network dns

Common Patterns

Hub-Spoke Topology

Hub VNet
├── Azure Firewall
├── VPN/ExpressRoute Gateway
├── Bastion Host
└── Central services

Spoke VNets (peered to hub)
├── Application Spoke
├── Data Spoke
└── Management Spoke

Private Endpoint Pattern

Connect to PaaS services privately:

1. Create private endpoint in your VNet
2. Disable public access on PaaS resource
3. Configure private DNS zone
4. Access service via private IP

CLI Reference

# Virtual Networks
az network vnet list --output table
az network vnet create -g RG -n VNET --address-prefix 10.0.0.0/16

# Subnets
az network vnet subnet list --vnet-name VNET -g RG --output table

# Private Endpoints
az network private-endpoint list --output table

# NSGs
az network nsg list --output table
az network nsg rule list --nsg-name NSG -g RG --output table

# Load Balancers
az network lb list --output table

Security Layers

Layer	Service	Purpose
4	NSG	IP/port filtering
7	Azure Firewall	Application rules, threat intel
7	WAF	Web application protection
Edge	DDoS Protection	Attack mitigation
