Relevant Scenarios
DTS can not only realize the rapid cloud migration between homogeneous databases, but also automatically complete the structure code conversion between heterogeneous databases during the migration. Users only need to conduct the simple migration task configuration according to following the process instruction, easily realize the online live cloud migration of self-built databases from the Internet.
Recommended Configuration
DTS + RDS
Data Transmission Service (DTS)
It provides database data transmission service integrating with the data migration, data synchronization and data subscription. It helps you easily complete the database migration without the suspension of business and easily build the high-availability database architecture for the remote disaster recovery by using the real-time synchronization channel.

Features
Database Migration
It supports the on-line live migration among the RDS, BCC self-built database and Internet self-built database. In turn, the migration process does not affect the normal operation of the source database. It supports the incremental migration, database table migration and object name mapping.
Database Synchronization
It supports the RDS in different regions to keep the real-time data synchronization, and easily build a high-availability architecture for the remote disaster recovery. It supports to modify the synchronization objects during the synchronization, and monitor and alarm the synchronization status, such as speed and delay.
Advantages
| Data Transmission Service (DTS) | Data Transmission Tool of Traditional Database | |
|---|---|---|
| Reliability | It ensures the secure transmission with 99.9% reliability and can perform the fault self-recovery of the transmission channel. Other nodes take over the task in case of transmission node fault. | The reliability cannot be guaranteed. The reliability is weak, so in case of a fault, the transmission is interrupted, and manual intervention is required. |
| Usability | It provides the process task configuration and activation and the visual task management, needs not to modify the source database, and is easy to operate. | The configuration and management are complex, and this puts forward high requirements for operators. |
| Transmission Performance | It transmits the resources in the Cloud through the private network, and the data transmission performance is high. | The data transmission performance is low. |
| Functional Support | It supports data transmission between multiple homogeneous databases and heterogeneous databases, and supports migration and real-time synchronization. The data transmission does not affect the normal operation of the source database, and it provides a wide range of features. | It has a single feature, and only supports the full migration or synchronization. The migration process may affect the source database service. |
| Cost | The billing rate and the service cost are low, and the migration service is only charged for the incremental migration. | The commercial transmission tools are expensive, and the service cost is high. |
