Overview
Scenario
Direct Connect establishes a dedicated, secure, stable, and high-speed network connection between your on-premises data center and VPCs. Direct Connect allows you to use global DC gateways to build a large-scale hybrid cloud network globally.
To improve the reliability of the hybrid cloud network and reduce costs, you can request two Direct Connect connections that work in an active/standby pair and use an enterprise router for dynamic route selection and switchover between Direct Connect connections. If the active connection becomes faulty, the standby one automatically takes over, which minimizes service interruptions.
In this example, you use an enterprise router, a pair of active/standby Direct Connect connections, and two global DC gateways to set up a hybrid cloud network.
Architecture
To improve the reliability of the hybrid cloud network and reduce costs, your enterprise uses a pair of active/standby Direct Connect connections to connect your on-premises data center to the VPCs. Both connections are associated with one enterprise router for automatic switchover. If the active connection becomes faulty, the standby one automatically takes over, which minimizes service interruptions.
Advantages
An enterprise router and two global DC gateways are used for active/standby switchover between two Direct Connect connections.
- This solution improves the network performance and reliability of the hybrid cloud network and prevents service interruptions caused by the failure of a single connection.
- The standby connection can be more cost-effective than the active one, which helps reduce costs.
- The outbound connection is specified, which simplifies O&M.
Constraints
The CIDR blocks of the VPCs and of the on-premises data center cannot overlap.
