# Virtual Hub

Azure Virtual Hub is a centralized networking hub used in Azure Virtual WAN. It provides scalable routing, connectivity, and security services for connecting virtual networks, VPNs, ExpressRoute circuits, and remote users. It simplifies large-scale network architecture by acting as a managed transit hub.
