Global VNet Peering? This function has recently come to my attention while working with an international customer who is in the process of integrating into their new owners Azure Active Directory. Global VNet peering enables resources in your virtual network to communicate across Azure regions privately through the Microsoft backbone. Resources communicate directly, without gateways, extra hops, or transit over the public internet. This allows a high-bandwidth, low-latency connection across peered virtual networks in different regions.
You can use Global VNet Peering to share resources within a global, private network. You can then easily replicate data across regions for redundancy and disaster recovery.
In my case I was integrating the Active Directory Domains and using Azure Active Directory Connector located in primary region to synchronize the AD Objects from one domain into the other. This approach provided a quick and simply migration without really complexity.
Global Vnet Peering is only currently supported for the following regions.
- Americas: West Central US (Wyoming), West US 2 (Washington), Central US (Iowa), US East 2 (Virginia), Canada Central (Toronto), Canada East (Quebec City)
- Asia Pacific: Southeast Asia (Singapore) Korea South (Buscan), South India (Chennai), Central India (Pune), West India (Mumbai)
- Europe: UK South (London), UK West (Cardiff), West Europe (Netherlands)
