What is the difference between Azure Virtual WAN and VPN gateway?

Summary

Experience with Azure Virtual WAN and VPN Gateway

While working with Azure Virtual WAN and VPN Gateway, I found that understanding the differences between the two is crucial for successful implementation. Here are some key points I’ve learned:

Azure Virtual WAN vs VPN Gateway

Azure Virtual WAN and VPN Gateway are two distinct services offered by Azure. The main difference lies in their functionality and purpose:

1. Azure Virtual WAN

Azure Virtual WAN is a comprehensive networking service that combines various functionalities, including branch connectivity automation through SD-WAN or VPN CPE partners. It provides a single operational interface for managing networking, security, and routing.

2. VPN Gateway

A VPN Gateway, on the other hand, is a type of virtual network gateway within Azure. It consists of Azure-managed virtual machines deployed in a specific subnet called GatewaySubnet. These VMs handle routing tables and specific gateway services.

Key Points
