What does Alibaba Cloud Data Transmission Service (DTS) do?

Alibaba Cloud Data Transmission Service (DTS) primarily facilitates data migration and replication between databases, making it a crucial tool for organizations looking to move their data seamlessly. This service supports various database types, including both homogeneous (same type) and heterogeneous (different types) databases, allowing users to transfer data from one database to another efficiently.

DTS offers several key capabilities, such as online migration, which allows for minimal downtime, and real-time data synchronization, enabling businesses to ensure their databases are consistently updated. This functionality is vital for application continuity and helps organizations maintain data integrity during migration processes.

The other options, while related to data management and services, do not specifically describe the primary purpose of DTS. For example, providing real-time data streaming services pertains more closely to event-driven architectures and services focused on real-time data processing. Data visualization is about interpreting and presenting data insights, which is outside the direct functionality of DTS. Similarly, securely archiving database information involves storing data for long-term retention, rather than the migration and replication processes that DTS specializes in.
