VNet Connectivity Decision Tree

Choosing between these two connectivity methods depends on your network design, latency limits, and security rules. You should evaluate the following criteria to determine the best path for your data:

• Choose VNet Peering when you require the highest possible speed and lowest latency for communication within the cloud.
• Choose a VPN Gateway when you must connect a physical on-premises datacenter or need to encrypt data in transit over a public network path.
• Choose a combination of both when building a hub-and-spoke topology, where a central hub contains the gateway and spokes connect to the hub via peering.
