Overview

What Is a Global DC Gateway?

A global DC gateway can work with enterprise routers in the same region or different regions to build a central network so that your on-premises data center can access the VPCs over the Huawei backbone network. This can reduce network latency, simplify network topology, and improve O&M efficiency.

A global DC gateway can only be associated with connections terminated at the same Direct Connect location. If there are multiple connections terminated at different Direct Connect location, you need to create multiple global DC gateways.

Global DC gateways have been launched in some regions. You can view the regions where this feature is available on the console.

Application Scenarios

Connecting an On-Premises Data Center to VPCs in Different Regions

A global DC gateway can be attached to enterprise routers in different regions.

If you need to use a central network for cross-region VPC communication, submit a service ticket.

Connecting an On-Premises Data Center to VPCs in the Same Region

A global DC gateway can be attached to enterprise routers in the same region.
