Hub-spoke network topology

  • The hub-spoke is a network topology in Azure where one virtual network acts as a hub, and other virtual networks as spokes.

  • In usual setting, the virtual network acting as a hub hosts central services and connections, like VPN connection to on-premises network. The spokes are connected to the hub with virtual network peering, mening that spokes can use services and connections provided by the hub.

  • In addition, the hub can control connectivity and security, for example using Azure Firewall

  • With default configuration, spokes are isolated from each other
