Networking topologies
In a decentralized data environment, data can only be shared by linking the decentralized zones together. These connections are made using Azure Virtual Network peering (https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-peering-overview). The advantage of using Azure Virtual Network peering is that the latency of exchanging data between networked peers is the same as the latency of resources exchanging data within the private network. So, users from two different landing zones that are peered over an Azure Virtual Network see no difference in the speed of data transfer, so long as the two networks are in the same region. The Azure Virtual Network uses the high bandwidth Azure backbone network to connect the two peered zones.
The traffic between these peered networks is managed using forwarding rules that are configured when peering is enabled. These rules define how traffic is allowed to move between the two peered networks. For details...
