We can connect 2 VNET using following options:
- VNET Peering
- VPN Gateway
VNET Peering is the best option as it gives fastest connectivity using the Microsoft backbone infrastructure using Private addresses.
There are 2 types of VNET Peering:
- VNET Peering for same region connectivity
- Global VNET Peering for different region connectivity
If you have one of the VNET in an On-Premise then you can choose the VPN Gateway option. It also offers Encryption which could make a decision.
However VPN Gateway will be slower compared with Peering, More Configuration & More Setup Time overheads exists.
