Cloud Enterprise Network (CEN) can implement network communication in the same region or across regions by establishing private connections between virtual private clouds (VPCs) or between VPCs and data centers. In addition, CEN supports custom communication, isolation, and redirect policies within a region. This allows you to establish a global enterprise-class private network that is also flexible, reliable, and large-scale. This topic describes common networking scenarios of CEN.

Same-region networking

CEN allows you to connect network instances that are deployed in the same region.

To connect network instances that are deployed in the same region, you must create a CEN instance and attach the network instances to the CEN instance.

Same-region networking

Cross-region networking

CEN allows you to connect network instances that are deployed in different regions.

For example, to connect a VPC in the Australia (Sydney) region to a VPC in the China (Shanghai) region, you must first create a CEN instance. Then, attach both VPCs to the CEN instance, purchase a bandwidth plan, and then set cross-region bandwidth.

Cross-region networking

Hybrid-cloud networking

CEN allows you to connect network instances of different types. You can create a hybrid-cloud network by connecting network instances of different types.

You can use CEN to connect network instances of different types, including VPCs, virtual border routers (VBRs), and Cloud Connect Network (CCN) instances. By connecting the preceding network instances, CEN can establish private connections between VPCs and data centers. This way, networks in the cloud can communicate with on-premises networks.

Enterprise-class networking

CEN allows you to create custom communication, isolation, and redirect policies within a region. You can use CEN to establish an enterprise-class network.

For example, you can use CEN to create custom route maps to enable the VPCs attached to the CEN instance to access the Internet from the same egress. This facilitates network management and improves the security of your workloads.
