Azure virtual Network Peering setup between different region and different resource group (step by step)

In this lab, I already created  two resource groups (Prod-dev and Uat-dev) in different regions as shown in figure.

And the I had two virtual networks, prod-vnet and uat-vnet both are placed in different regions and different resource groups.

Also I had two virtual machines, prod-vm1 (in EastUS ) uat-vm1 (in East Asia).

By default, we cannot talk or communicate between uat-vm1 and prod-vm1 because both of the virtual do not have the same virtual network, region and resource group. In this situation, we have to create "virtual network peering " to communicate between these different virtual network.

I already open "RDP Port 3389" in Both vm's network security group's inbound connection to access remote Desktop connection. 

Now I login into both virtual machines and test network connectivity between these two virtual machine whether they can talk each other or not with ping command.

prod-vm1 private ip address :10.1.0.4    

uat-vm1 private ip address : 192.168.1.4

Test connection from uat-vm1 to prod-vm1 beforce virtual network peering.

Test connection from prod-vm1 to uat-vm1 beforce virtual network peering.

So we need to solve this problem by creating virtual network peering.

Go to uat-net (virtual network) and click "peering" tab.

And Click "ADD"

1. Type the name of your peering 
2. Select you subscription 
3. Select virtual network that you want to talk with your uat-dev-net ( I choose prod-dev-net because i want to talk with this network)

4. "Enable " allow virtual network access from uat-dev-vnet to prod-dev-vnet ( to communicate uat-vm1 and prod-vm1)

5.Leave other option default ( I will explain other option in the next lesson and press OK to continue)

Now Test connection again from uat-vm1 to prod-vm1 after virtual network peering

That's all.

Hope you enjoy learning.
