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.

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.
