Dependent Service Migration

Migrate the data of services that a cluster depends on, such as storage, database, distributed cache, and distributed message. If your cluster does not involve the data of these services or the data does not need to be migrated to Huawei Cloud, skip this section.

Storage Migration

  • If your cluster uses cloud disks, you can use Huawei Cloud Data Express Service (DES) for cross-cloud migration. DES is a massive data transmission solution. It allows you to migrate terabytes or even hundreds of terabytes of data to Huawei Cloud using Teleport devices or disks (with external USB interfaces, SATA interfaces, or SAS interfaces). It helps address issues facing massive data transmission such as high network costs and long transmission time.
  • If your cluster uses object storage, you can use Huawei Cloud Object Storage Migration Service (OMS) for cross-cloud migration. OMS is an online data migration service. It can migrate data from object storage services of other cloud service providers to Huawei Cloud OBS.
  • If your cluster uses file storage, you can use Huawei Cloud Scalable File Service (SFS) for cross-cloud migration. For details, see Data Migration.

Database Migration

If you need to migrate databases to Huawei Cloud, you can use Data Replication Service (DRS). For details, see Data Replication Service (DRS). DRS provides multiple functions, including real-time migration, backup migration, real-time synchronization, data subscription, and real-time DR.
