Private Network Access

Connecting to an On-premises Data Center

You can connect a VPC to your on-premises data center. Once you have established this secure, reliable connection, you can move at scale to Huawei Cloud, a cloud with massive computing, storage, and network resources. With Huawei Cloud, you will be unaffected by sudden fluctuations in demand for services. Both Direct Connect and VPN support the connections between your data center and your VPCs on the cloud.

  • Direct Connect

    Direct Connect provides high-speed, stable, and secure dedicated network connections that connect your data centers to VPCs. With Direct Connect, you can connect computers in your on-premises data center to cloud servers or hosting servers on Huawei Cloud. It maximizes cloud computing capacities and existing IT facilities to build a flexible, scalable hybrid cloud computing environment.

  • VPN

    VPN establishes a secure, encrypted communication tunnel between your local data center and your VPC on Huawei Cloud. With VPN, you can connect to a VPC and access the resources deployed there.

Connecting VPCs and Data Centers with Cloud Connect

Cloud Connect allows you to quickly build high-quality networks that can connect VPCs across regions and work with Direct Connect to connect VPCs and on-premises data centers.

With Cloud Connect, you can build a globally connected cloud network with enterprise-class scalability and communications capabilities.

Connecting VPCs

If you want to connect VPCs in the same region, you can use VPC peering connections.

If you want to connect VPCs in different regions and construct a service network across regions, you can use Direct Connect, VPN, or Cloud Connect.

  • VPC peering

    You can use VPC peering connections to connect VPCs in the same region.

  • Direct Connect

    Direct Connect provides high-speed, stable, and secure dedicated network connections that connect your data centers to VPCs. With Direct Connect, you can connect computers in your on-premises data center to cloud servers or hosting servers on Huawei Cloud. It maximizes cloud computing capacities and existing IT facilities to build a flexible, scalable hybrid cloud computing environment. Direct Connect can also be used to connect VPCs in different regions.

  • Cloud Connect

    Cloud Connect allows you to quickly build high-quality networks that can connect VPCs across regions and work with Direct Connect to connect VPCs and on-premises data centers. With Cloud Connect, you can build a globally connected cloud network with enterprise-class scalability and communications capabilities.
