Explanation

Azure Virtual WAN is a networking service that brings many networking, security, and routing functionalities together to provide a single operational interface. These functionalities include branch connectivity (via connectivity automation from Virtual WAN Partner devices such as SD-WAN or VPN CPE), Site-to-site VPN connectivity, remote user VPN (Point-to-site) connectivity, private (ExpressRoute) connectivity, intra-cloud connectivity (transitive connectivity for virtual networks), VPN ExpressRoute inter-connectivity, routing, Azure Firewall, and encryption for private connectivity. You do not have to have all of these use cases to start using Virtual WAN. You can simply get started with just one use case, and then adjust your network as it evolves.

The Virtual WAN architecture is a hub and spoke architecture with scale and performance built in for branches (VPN/SD-WAN devices), users (Azure VPN/OpenVPN/IKEv2 clients), ExpressRoute circuits, and virtual networks. It enables global transit network architecture, where the cloud hosted network 'hub' enables transitive connectivity between endpoints that may be distributed across different types of 'spokes'.

Azure regions serve as hubs that you can choose to connect to. All hubs are connected in full mesh in a Standard Virtual WAN making it easy for the user to use the Microsoft backbone for any-to-any (any spoke) connectivity. For spoke connectivity with SD-WAN/VPN devices, users can either manually set it up in Azure Virtual WAN, or use the Virtual WAN CPE (SD-WAN/VPN) partner solution to set up connectivity to Azure. We have a list of partners that support connectivity automation (ability to export the device info into Azure, download the Azure configuration and establish connectivity) with Azure Virtual WAN.
