The AWS Database Migration Service (DMS) is specifically designed to facilitate the migration of databases to AWS. It simplifies the process of transferring data between on-premises databases and AWS databases. DMS supports a variety of source and target databases, enabling both homogeneous migrations (where the source and destination databases are of the same type) and heterogeneous migrations (where the databases are of different types). Additionally, it minimizes downtime during the migration by allowing for continuous data replication until the migration is complete.

AWS DMS also automatically handles the complexities of database migration such as schema conversion and data validation, providing a streamlined approach to moving data into a cloud environment. This makes it an essential tool for organizations looking to modernize their database infrastructure by migrating to AWS.

The other options, while useful for various migration and data transfer tasks, do not specifically target database migrations. For instance, AWS Migration Hub provides a central location for tracking the progress of migrations across multiple AWS services, but it does not handle the actual database migration itself. AWS Snowball is geared towards transferring large amounts of data physically, and AWS Transfer Family is focused on transferring files via protocols like SFTP and FTPS, rather than migrating databases.
