Migrating Data Using CDN

MgC enables you to use CDN to migrate data from cloud storage services, such as Microsoft Azure Blob, Tencent Cloud COS, Qiniu Cloud KODO, Kingsoft Cloud KS3, Alibaba Cloud OSS, and Amazon S3.

Constraints

  • Migrating over CDN is slower than directly migrating from the source object storage system.
  • You can only manually check whether the authentication key is correct and whether the domain name can be properly resolved.
    • To verify the domain name resolution, create an ECS in the same security group, VPC, and subnet as the migration cluster. Run the following command to check whether the domain name can be resolved:
      dig/nslookup
    • To verify the authentication key, search for URL authentication in the CDN documentation of the source cloud platform.

Procedure

For details, see Migrating Data from Other Cloud Platforms to Huawei Cloud. When you create the migration workflow, in the Advanced Settings area, select Download Data from CDN and enter the corresponding authentication information. If the default domain name cannot meet your migration requirements, then as long as the source cloud service provider supports custom domain names, you can bind a custom domain name to the source bucket, and enable the CDN service on the source platform to reduce data download expenses. Enter a custom domain name in the Domain Name text box and select a transmission protocol. HTTPS is more secure than HTTP and is recommended.

If the migration source is the Alibaba Cloud OSS or Tencent Cloud COS, you also need to select an authentication type and enter an authentication key.
