vNet Peering

Virtual network peering enables you to seamlessly connect two or more Virtual Networks in Azure. The virtual networks appear as one for connectivity purposes. The traffic between virtual machines in peered virtual networks uses the Microsoft backbone infrastructure.


In this lecture, you’re introduced to the concept of vNet Peering within Microsoft Azure’s cloud computing services. You learn that vNet Peering is a process that connects two or more virtual networks in Azure, making them appear as one for connectivity purposes. This connection utilizes the Microsoft backbone infrastructure, ensuring that the traffic between virtual machines (VMs) on peered virtual networks remains secure.

You are made aware of two specific types of peering available in Azure: virtual network peering and global virtual network peering. The former connects virtual networks within the same Azure region, while the latter connects networks across multiple Azure regions.

The lecture emphasizes the benefits of vNet Peering, including low latency, high bandwidth connections, and the ability for resources in one vNet to communicate with those in another. It highlights the capability to connect virtual networks even if they are part of different Azure subscriptions, Azure Active Directory tenants, deployment models, or regions.

Importantly, you are informed that creating a peering does not cause downtime in either virtual network and that the traffic remains private and secure on the Microsoft backbone network, eliminating the need for public internet, gateways, or additional encryption.

In summary, the key points to remember from this lecture include the seamless connection of virtual networks through vNet Peering, the distinction between local and global peering, and the private nature of the network traffic on Azure’s infrastructure.
