Application Scenarios¶
Hybrid Cloud Deployment¶
You can use a VPN to connect your on-premises data center to a VPC and use the elastic and fast scaling capabilities of the cloud to expand application computing capabilities. Figure 1 shows the hybrid cloud deployment.

Cross-Region Interconnection Between VPCs¶
With VPNs, you can connect VPCs in different regions to enable connectivity between user services in these regions, as shown in Figure 2.
Figure 2 Cross-region interconnection between VPCs¶
Enterprise Branch Interconnection¶
A VPN gateway functions as a VPN hub to connect enterprise branches, as shown in Figure 3. This eliminates the need to configure VPN connections between every two branches.

Backup Between VPN and Direct Connect¶
For high reliability purposes, you can connect your on-premises data center to a VPC on the cloud through Direct Connect and VPN that back up each other, as shown in Figure 4.
