Networking Solution for the Scenario Where the Source Server Is in an On-premises Environment, Has No Internet Access, and Cannot Access Target Servers on the Cloud

This section describes how to use Direct Connect to connect the on-premises source server without Internet access to the target server on the cloud.

Using Direct Connect to Establish a Dedicated Channel

If the source server cannot access the Internet, you can use Direct Connect to enable the server to access the target Huawei Cloud VPC via a dedicated, high-bandwidth, low-latency connection for efficient data transfer. For details about Direct Connect and its billing, see What Is Direct Connect? and Direct Connect Billing.

When you apply for a Direct Connect connection to access Huawei Cloud, the telecom carrier needs to perform a site survey and lay the leased line, which takes about two or three months. Make sure that you leave enough time for the project.

Direct Connect provides best practices for different networking scenarios. Choose the one that best fits your needs.

Creating a Migration Task on SMS

After confirming that the network is connected, create and execute a migration task by following the instructions provided in Migration Process. Note that you must set Network Type to Private when configuring the task.
