Connecting Azure Virtual Networks with VNet Peering: A Comprehensive Guide
Virtual network (VNet) peering is a powerful feature in Microsoft Azure that allows you to connect two virtual networks in the same region or different regions. This can be useful for scenarios such as:
Connecting VNets in different subscriptions to enable cross-subscription communication.
Connecting VNets in the same region to enable communication between different applications or services.
Merging two or more VNets into a single VNet for easier management and better control.
What is VNet peering?
VNet peering allows you to connect two VNets using Azure’s backbone network. This connection is private, secure, and low-latency, which means that the traffic between the two VNets does not go over the public internet.
VNet peering can be set up between VNets in the same region or different regions, and even between VNets in different subscriptions. When two VNets are peered, they appear as one network, which means that resources in one VNet can communicate with resources in the other VNet using their private IP addresses.
VNet peering is different from VNet-to-VNet VPN connections, which are also used to connect two VNets. VNet peering is generally preferred over VNet-to-VNet VPN connections because it provides better performance, scalability, and security.
