Implementing a global transit network architecture using VWAN
One of the advantages of implementing Azure VWAN for connectivity is its support for an “out-of-the-box” global transit network architecture. This is because it allows any-to-any connectivity between all connections to VWAN (branches, VNets, and users)! This removes or reduces the need for full mesh or partial mesh connectivity between multiple networks.
Figure 7.49 – Azure VWAN supports any-to-any connectivity
For example, in the scenario highlighted in Figure 7.49, VWAN supports the following global transit connectivity paths without the need for any additional routing configuration:
- Branch to VNet
- Branch to branch
- Remote user to VNet
- Remote user to branch
- VNet to VNet
- Branch-to-hub-to-hub-to-Branch
- Branch-to-hub-to-hub-to-VNet
- VNet-to-hub-to-hub-to-VNet
