Connection Overview

Connections are dedicated channels for on-premises data centers to access the cloud. Connections are more stable, reliable, and secure than Internet-based connections, and provide up to 100 Gbit/s of bandwidth. Direct Connect provides ports only. After you request a connection, you need to work with the carrier and Huawei Cloud to establish network connectivity between your on-premises data center and the cloud.

Direct Connect provides standard connections and hosted connections.

• 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.
  You can choose self-service connections or full-service connections.

  • Self-service connection: Huawei Cloud only provides the port. You need to create a connection on the console, and lease a line from a carrier.
  • Full-service connection: You only need to create a connection on the console, and Huawei Cloud will complete all operations required for network connectivity.

  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. The connection is created by a carrier (a partner of Huawei Cloud), who allocates the required VLAN and bandwidth for your connection. Only one virtual interface can be associated with each hosted connection.

  If you are a partner, you can request operations connections. If you are a common user, you can purchase a host connection from your partner. Hosted connections must be hosted on operations connections, and your partner will allocate VLAN and bandwidth resources to the connection.

  Figure 2 shows an example of how hosted connections work.

Connections support redundant configuration. If there are two connections terminated at different locations in the same region, they can work in an active/standby pair to back each other up. If one connection becomes faulty, the other will take over, ensuring stable services.
