Azure - Networking

Understand the purpose of virtual networks to isolate traffic and enable inter-machine communication, while connecting to on-prem resources via gateways and managing dynamic IPs, VIPs, and instance public IPs.

Plan virtual networks before deployment to avoid rework after setup. Use non-overlapping private IP address spaces in Azure and on-premises, and account for four reserved addresses in each subnet.

Configure dns at the virtual network level using PowerShell, CLI, or portal; Azure handles dns for cloud services in the vnet, with option to deploy your dns for on-premises resolution.

Create and configure a virtual network in Azure by choosing a non-overlapping address space, adding a default subnet, and preparing resource group and region to deploy a virtual machine.

Learn to connect Azure virtual networks with site-to-site and point-to-site VPNs using IPsec, and compare gateway sizes from basic to gateway 3 for production throughput.

Configure a point to site vpn by creating a vnet gateway and gateway subnet, selecting route-based vpn, and setting up root and client certificates for the vpn client.

Configure a site-to-site vpn by creating a virtual network gateway, adding a local network gateway, and establishing a pre-shared key connection to enable encrypted cross-region traffic.

Learn how VNet peering lets two virtual networks communicate via Microsoft's private network, avoiding public internet. The session notes regional limits, cross-region preview, and gateway traffic to reach on-premises networks.

Summarize Azure virtual networks, IP address spaces, DNS, and portal setup for VPNs. Cover site-to-site and point-to-site VPNs, gateways, certificates, VNet peering, and cross-region private connectivity.
