Global DC Gateway Overview

Updated on 2025-01-22 GMT+08:00

What Is a Global DC Gateway?

A global DC gateway enables your on-premises data center to access VPCs in multiple regions so you can use a single connection to provide high-speed access to cloud compute and storage resources in any region.

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.

NOTE:

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

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

A global DC gateway can be attached to enterprise routers in different regions. This can reduce the network latency, simplify network topology, and improve network O&M efficiency.

NOTE:

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 for network communication. This can reduce the network latency, simplify network topology, and improve network O&M efficiency.
