Overview

Scenario

Direct Connect establishes a dedicated, secure, stable, and high-speed network connection between your on-premises data center and VPCs. Direct Connect now provides global DC gateways that allow you to build a large-scale hybrid cloud network globally.

Enterprise Router helps choose the fastest possible route dynamically and switch between Direct Connect connections. It balances the load among connections and fully uses the network bandwidth. This makes network transmission faster, more reliable, and better performing.

In this example, we use an enterprise router, two Direct Connect connections, and two global DC gateways to set up a hybrid cloud network.

Architecture

To improve the performance and reliability of the hybrid cloud network, your enterprise uses two Direct Connect connections to connect your on-premises data center to the VPCs. The two Direct Connect connections work in load balancing mode. When both connections are working normally, network transmission is greatly improved. If one connection is faulty, the other connection ensures the normal running of the hybrid cloud network and thereby prevents service interruptions caused by a single connection

The two VPCs can communicate with each other and communicate with the on-premises data center over two Direct Connect connections and an enterprise router.
When one Direct Connect connection is faulty, the two VPCs can communicate with the on-premises data center over the normal connection.

Advantages

Enterprise Router and global DC gateways enable two Direct Connect connections to work in load balancing mode. This improves the network performance and reliability of hybrid cloud networking and prevents service interruptions caused by a single connection.
