What Is Cloud Connect?

Cloud Connect provides central networks that allow you to connect Virtual Private Clouds (VPCs) in different regions, so that these VPCs can communicate over a private network as if they were within the same network. Cloud Connect can also work with Direct Connect to set up a hybrid cloud network that enables on-premises data centers to access the VPCs across regions.

  • Connect VPCs in different regions by attaching them to enterprise routers in the corresponding regions.
  • Connect on-premises data centers to VPCs in different regions by attaching them to enterprise routers in the corresponding regions.
 You need to buy and bind a global connection bandwidth to the central network and assign cross-site connection bandwidths to enable communication between the resources in different regions.
  • Flexible networking
  • Dynamic routing
  • A variety of attachments and network scenarios
  • Enterprise routers in different regions are connected.

Central Network

Relying on the cloud backbone network, a central network allows you to easily set up a reliable, intelligent enterprise-grade network and manage global network resources on premises and on the cloud. By setting up a central network, you can enable communication between enterprise routers, in the same region or different regions.

In Figure 1 <cc_01_0001__fig8481153843220>, the two VPCs (VPC-A01 and VPC-A02) are attached to an enterprise router (ER-A) in region A, two VPCs (VPC-B01 and VPC-B02) are attached to an enterprise router (ER-B) in region B, and two VPCs (VPC-C01 and VPC-C02) are attached to an enterprise router (ER-C) in region C.

The three enterprise routers (ER-A, ER-B, and ER-C) are connected over a central network. In this way, the enterprise routers can communicate with each other across regions, and the VPCs in these regions can communicate with each other.

Table 2 Central network concepts
Concept Description
Enterprise router An enterprise router enables the VPCs in the same region to communicate with each other. Enterprise routers in different regions can be connected using a central network to allow for cross-region communication between VPCs.
Global connection bandwidth

A global connection bandwidth can be bound to a central network to allow the resources to communicate with each other over the backbone network, regardless of whether:

  • The resources are in the same geographic region.
  • The resources are in different geographic regions.

Accessing Cloud Connect

You can access Cloud Connect through the management console or by calling HTTPS-based APIs.

  • Using the management console

    The management console is a web-based GUI where you can easily perform various operations. Log in to the management console and choose Cloud Connect from the main menu.

  • Using APIs

    If you need to integrate Cloud Connect into a third-party system for secondary development, you can use APIs to access Cloud Connect. For details, see the Cloud Connect API Reference.
