Cloud Connect (CC) is a HUAWEI CLOUD service that allows you to connect Virtual Private Clouds (VPCs) so that you can build a globally connected cloud network with enterprise-grade scalability and communication capabilities. Cloud Connect (CC) enables you to establish secure high-speed connections among VPCs in different regions to meet growing cloud usage requirements while reducing operational costs.
With Cloud Connect (CC), you can quickly build ultra-fast, high-quality, and stable networks between VPCs across regions and between VPCs on the cloud and data centers off the cloud. CC helps you build a global cloud network with enterprise-class scale and communication capabilities.
After you create a cloud connection, you need to load network instances from different cloud regions to the connection and configure the bandwidth for the network instances to enable network communication between them. (A network instance can be a VPC you create, a VPC authorized by another user, or a virtual gateway you create for access from your on-premises data center.)
Basic Concepts
Virtual gateway
A virtual gateway is a resource in Direct Connect, and it functions as a router for a connection to access the cloud.
A Direct Connect connection is a dedicated network connection between an on-premises data center and the cloud. To access the cloud, a virtual interface is also required, which serves as the entry point for the data center to access the cloud. A virtual gateway connects a virtual interface to a VPC so that the data center can access the VPC.
Network instance
A network instance is a VPC or virtual gateway that you load to a cloud connection for network communication.
You can load VPCs to a cloud connection to enable communications among VPCs.
After you load a virtual gateway to a cloud connection, the on-premises data center can communicate with one or more VPCs, building a hybrid cloud.
Bandwidth package
A bandwidth package provides bandwidth for communications among network instances in different cloud regions. You can buy a bandwidth package to enable:
Communications among network instances in cloud regions within a geographic region
Communications among network instances in cloud regions of different geographic regions
You do not require bandwidth packages for communication among network instances in the same cloud region.
Inter-region bandwidth
An inter-region bandwidth is used for network communication of instances in two regions. Total inter-region bandwidths cannot exceed the bandwidth you specify when you buy the bandwidth package.
In Figure 3, a bandwidth package is divided into three inter-region bandwidths for communication between the Chinese mainland and Asia Pacific.
Accessing Cloud Connect
A web-based user interface is provided for you to access CC.
log in to the management console and choose Networking > Cloud Connect on the homepage.
Advantages of Cloud Connect:
Full connectivity
You can connect VPCs in any region to build a multi-VPC network without using additional links.
Ease of use
In just four simple steps, you can build cross-region VPC connectivity to securely connect and use cloud resources in multiple VPCs.
High performance
CC leverages Huawei's global network infrastructure to provide low-latency and high-quality experience. You can flexibly adjust bandwidth to meet your business requirements.
Globally compliant
CC complies with local laws and regulations worldwide, allowing you to focus on innovation and build business success.
Some Scenarios:
Communications Among VPCs Across Regions
CC helps you realize secure and reliable private network communication among VPCs in different cloud regions and improve network topology flexibility. Figure 4 shows the communications among VPCs in different cloud regions. The VPCs can be your VPCs or other VPCs that you have been authorized to access.

Communication Between Data Centers and VPCs in Different Regions
If you want to establish communication between multiple on-premises data centers and VPCs in multiple cloud regions, use Direct Connect to connect a data center to a VPC and then load this VPC, virtual gateways connected to data centers, and the other VPCs to a cloud connection to build a fully connected network. The VPCs can be your VPCs or other VPCs that you have been authorized to access.
