Virtual WAN Hub
Definition
Azure's central networking point that connects multiple networks, branch offices, and VPN connections, simplifying network architecture and management.
Use Cases
- KPMG: Connect many offices and client environments to Azure-hosted applications with consistent routing and security controls. — KPMG has publicly described using Microsoft Azure networking capabilities as part of its cloud platform; a common enterprise pattern is to use Azure Virtual WAN hubs to aggregate site-to-site VPN/SD-WAN connections, connect multiple VNets, and centralize routing through secured hubs. (Centralized connectivity and simplified operations compared with managing many independent VPN gateways and custom routing per VNet, improving scalability for adding new sites and networks.)
- Heineken: Global network modernization to connect distributed locations to cloud services with standardized connectivity. — Heineken has publicly discussed Azure adoption for global IT modernization; a typical implementation approach is to use a managed hub (Azure Virtual WAN hub) to terminate branch connectivity and connect to multiple Azure VNets, reducing per-region bespoke network builds. (Faster rollout of connectivity to new locations and more consistent network governance through a centrally managed hub model.)
- Siemens: Hybrid connectivity for large-scale enterprise workloads spanning on-premises and Azure regions. — Siemens has publicly referenced Azure usage for enterprise and industrial solutions; a common architecture is to use Azure Virtual WAN hubs to aggregate VPN/ExpressRoute connectivity and route traffic between many VNets and on-prem networks using centralized policies. (Improved manageability and scalability for hybrid networking by reducing the need for complex, point-to-point connectivity between networks.)

Frequently Asked Questions
- What's the difference between Azure Virtual WAN hub and a hub VNet (traditional hub-and-spoke)?
- A hub VNet is something you build and manage yourself (VNets, VPN/ExpressRoute gateways, route tables, NVAs/firewalls, and peering). An Azure Virtual WAN hub is a Microsoft-managed hub inside the Virtual WAN service that provides built-in routing and simplified connectivity for many branches and VNets. Virtual WAN hubs are designed to scale for large numbers of sites and connections with less custom routing work than a DIY hub VNet.
- When should I use Virtual WAN hub?
- Use it when you need to connect many branch offices, remote users, or multiple VNets across regions and want centralized, managed routing. It’s especially useful if you expect frequent growth (new sites/VNets), want to integrate SD-WAN partners, or want a standardized hub model across multiple regions. If you only have a small number of VNets and a couple of on-prem connections, a traditional hub VNet with peering may be simpler.
- How much does Virtual WAN hub cost?
- Cost depends on several factors: the Virtual WAN hub hourly (or per-unit) charges, the number and type of connections (VPN, ExpressRoute, VNet connections), and data processing/egress charges. Pricing varies by region and by features used (for example, secured hub/firewall scenarios can add cost). For accurate numbers, use the Azure Pricing page for Virtual WAN and the Azure Pricing Calculator with your expected number of hubs, connections, and monthly data transfer.
