Application Scenarios

Migrating Enterprise Data to the Cloud

Big data cloud services can replace or back up on-premises big data platforms and support full migration of massive amounts of data. 

Advantages

  • Various Data Sources

    Support for relational databases, big data, files, NoSQL, and many other data sources ensures a wide application scope. 

  • Easy to Use

    Wizard-based task management provides out-of-the-box usability. 

  • Secure and Efficient

    Fully-managed services ensure security and enhance the migration performance of Hive, HBase, and DWS.

Migrating Data Between Cloud Services

Data is migrated between services on Huawei Cloud, achieving data mobility.

Advantages

  • Heterogeneous Data Sources

    Structured and unstructured data can be directly migrated.

  • Secure

    Data is migrated between tenant VPCs rather than being written to local disks, thereby improving efficiency and security.

Migrating Data to On-Premises Systems

Computing resources on the public cloud can be used to process huge data sets. The processing results are then returned to on-premises service systems (relational databases and file systems).

Advantages

  • Various On-Premises Service Systems

    Analysis results can be returned to various on-premises databases or file systems.

  • Easy to Use

    Wizard-based task management provides out-of-the-box usability.

Migrating Incremental Data

After a full synchronization is performed, incremental data needs to be synchronized.

Advantages

  • Incremental Data Synchronization

    The scheduling system supports the WHERE clause used in migration jobs so that incremental synchronization can be implemented in an efficient manner.

  • Efficient

    The migration performance of DWS, Hive, and MySQL is improved.
