What Is Cloud Connect?

Cloud Connect provides both cloud connections and 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.

Advantages

Central Network
  • 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 Huawei backbone network, a central network enables communication between enterprise routers, in the same region or across regions, as well as between enterprise routers and on-premises data centers. By applying policies on a central network, you can set up an enterprise-grade network that features flexibility, reliability, and intelligence.

  • Connecting VPCs in different regions

    In Figure 1, 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.

  • Connecting on-premises data centers to VPCs in different regions

    In Figure 1, the two VPCs in each region are attached to an enterprise router, and the on-premises data center in each region is connected to the two VPCs in that region over a Direct Connect connection. The global DC gateways for each on-premises data center are attached to the enterprise router in each region, and the enterprise routers in the three regions are connected over the central network.

    In this way, the VPCs in all the regions can communicate with each other, and the two on-premises data centers can communicate with all the VPCs in the three regions.

    Table 2 explains some concepts related to central networks.

Description

Enterprise router

An enterprise router enables the VPCs in the same region to communicate with each other. By working with global DC gateways provided by Direct Connect, enterprise routers enable the VPCs and on-premises data centers 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 and between on-premises data centers and VPCs. For more information about enterprise routers, see What Is an Enterprise Router?

Global DC gateway

Global DC gateways can work with enterprise routers to allow on-premises data centers to communicate with the VPCs over a hybrid cloud network. A global DC gateway can be attached to enterprise routers in different regions on a central network. This reduces latency, simplifies network topology, and improves network O&M efficiency.

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.

For more information, see Geographic-region/Cross-geographic-region Bandwidth Application Scenario (Central Network).

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.
