Azure Virtual WAN is an Azure networking service that centralizes connectivity and routing for distributed environments, used by network and platform teams to connect branch offices, remote users, and Azure virtual networks through managed hubs. It helps reduce configuration sprawl across individual gateways and route tables while supporting consistent governance across regions and sites.
It is typically implemented as a global transit layer in hub-and-spoke architectures, integrating with VPN, ExpressRoute, and security services to streamline routing, inspection patterns, and operational visibility. More details are available in the Microsoft Learn overview.
Networking, in the context of computer science and information technology, refers to the practice of connecting computers, servers, mainframes, network devices, peripherals, or other devices to exchange data and share resources. It encompasses both the physical (hardware) and logical (software) aspects of connections between devices. The primary goal of networking is to enable the sharing of data and resources, thereby improving efficiency and accessibility within and across computing environments. Networks can vary in size, ranging from simple local area networks (LANs) connecting a few devices in a single office, to complex wide area networks (WANs) spanning multiple geographic locations around the globe. Networking technologies and protocols facilitate communication and data transfer across these connections, adhering to standardized rules to ensure reliable and secure information exchange.
Azure Virtual WAN is a managed, hub-and-spoke networking service that centralizes routing, connectivity, and security for distributed environments. It is used to connect branch offices, remote users, and Azure virtual networks with consistent policy and simpler operations.
Azure Virtual WAN is a strong fit for organizations with many branches or multiple Azure regions that need consistent routing and security. Trade-offs include service limits and feature constraints compared to fully custom NVA-based hubs, and costs that can increase with high throughput or many connections.
Common alternatives include Azure hub-and-spoke VNets with Azure VPN Gateway and ExpressRoute Gateway, or SD-WAN platforms such as Cisco SD-WAN (Viptela), Fortinet Secure SD-WAN, and VMware SD-WAN.
Our experience with Azure Virtual WAN helped us build repeatable reference architectures, automation, and operational practices for clients who needed centralized routing, security controls, and consistent connectivity across branches, Azure VNets, and remote users.
