Virtual network peering enables you to seamlessly connect two or more [virtual networks](virtual-networks-overview.md) in Azure. The virtual networks appear as one for connectivity purposes. The traffic between virtual machines in peered virtual networks uses the Microsoft backbone infrastructure. Traffic is routed through the Microsoft *private* network only.

Azure Virtual Network peering enables you to seamlessly connect two or more virtual networks in Azure, making them appear as one for connectivity purposes. This powerful feature allows you to create secure, high-performance connections between virtual networks while keeping all traffic on Microsoft's private backbone infrastructure, eliminating the need for public internet routing.

By default, a virtual network is peered with up to 500 other virtual networks. By using the [connectivity configuration for Azure Virtual Network Manager](../virtual-network-manager/concept-connectivity-configuration.md), you can increase this limit to peer up to 1,000 virtual networks to a single virtual network. With this larger size, you can create a hub-and-spoke topology with 1,000-spoke virtual networks, for example. You can also create a mesh of 1,000-spoke virtual networks where all spoke virtual networks are directly interconnected.
