Creating and configuring VNet-to-VNet connection

When building different computer systems, you often have to encapsulate them inside different networks so that they are isolated from each other and possibly from external traffic; however, there are cases when two separate VNets need to be able to connect so that they can exchange communication. In the previous section, you implemented a peering between two VNets—this time, we will show you the other option for integrating them. Knowing an alternative solution may be helpful, especially with global peering, as there are some problems with load balancers in that kind of setup; such problems include being unable to communicate with some services using the frontend IP of a load balancer if the load balancer used is a basic one.

In this section, we will consider two different options:

• VNet-to-VNet connections in the same region
• Cross-region VNet-to-VNet connections

To get started, you will have to consider two different setups:

• Two VNets in the same region
• Two VNets in different regions

We will use the commands in the following sections to prepare our own environment.
