Standard Connection

A standard connection provides an exclusive port. You can create standard connections on the management console. To improve reliability, you can create multiple connections terminated at different locations and allow them to serve as backups for each other. If you can select only one carrier due to special requirements, you must configure different physical routes for your connections.

Figure 1 shows an example of how standard connections work.

Hosted Connection

If you use a hosted connection to access the cloud, the port you use is shared with other users. You request a carrier (a partner of Huawei Cloud) to provide a connection to connect to your on-premises data center to Huawei Cloud. The partner has pre-connected dedicated lines terminated at the Direct Connect locations of Huawei Cloud and allocates a connection port to you after receiving your request. This connection port is shared with other users.

Figure 2 shows an example of how hosted connections work.

Full-Service Installation

Huawei Cloud completes all operations required for connecting your on-premises data center to the cloud, including integrating the network resources and ports.

Figure 3 shows the entire process.

Direct Connect Gateway

• Virtual gateway: A virtual gateway is a logical gateway for accessing VPCs. To access other VPCs, you can use VPC Peering or Cloud Connect to connect the VPC your on-premises data center is accessing to these VPCs.

  A virtual gateway can be associated with only one VPC, and multiple connections can access a VPC through the same virtual gateway.

  For details, see Virtual Gateways.

• Global DC gateway: A global DC gateway enables your on-premises data center to access VPCs in multiple regions so you can use a single connection to provide high-speed access to cloud compute and storage resources in any region.

  A global DC gateway can only be associated with connections terminated at the same Direct Connect location. If there are multiple connections terminated at different Direct Connect locations, you need to create multiple global DC gateways.

  For details, see Global DC Gateways.

Virtual Interface

A virtual interface can link a connection with one or more virtual gateways, so that your on-premises network can access the VPC associated with each virtual gateway.

Virtual interfaces support static routing and BGP routing. During the establishment of network connectivity, you can use BGP to connect on-premises data centers to virtual gateways. BGP helps you build a hybrid cloud more efficiently, flexibly, and reliably.

For details, see Virtual Interfaces.
