VNet peering is a mechanism that seamlessly connects two VNets in the same region through the Azure backbone infrastructure. Once peered, the VNets appear as one for connectivity purposes, just like routing traffic between VMs that are created in the same VNet. The VMs that reside in the peered VNets communicate with each other using private IP addresses.
Azure supports the following two different types of peering:
- VNet peering: This is used for connecting VNets in the same Azure region.
- Global VNet peering: This is used for connecting VNets across different Azure regions.
The network traffic between peered VNets is private. The traffic is kept on the Microsoft backbone network completely, so there is no need for using any additional gateways, or route traffic over the public internet. There is also no encryption required in the communication between the peered...
