Networking
Connect and secure Azure resources.
📖 Key ideas
- Virtual Networks (VNets) are private networks.
- Subnets segment VNets; NSGs filter traffic.
- Load Balancer (layer 4) and Application Gateway (layer 7, with WAF).
- Azure DNS and Front Door for global routing.
- VPN Gateway and ExpressRoute connect on-premises networks.
💡 Real-life example: A VNet is a private road network; NSGs are traffic police at every junction.
