Answer: AWS Database Migration Service (AWS DMS)

## Explanation AWS Database Migration Service (AWS DMS) is specifically designed for migrating databases to AWS with minimal downtime. Here's why it's the correct choice: ### Key Features of AWS DMS: - **Minimal Downtime**: Uses continuous data replication during the migration process, allowing the source database to remain operational - **Database Support**: Supports homogeneous migrations (same database engine) and heterogeneous migrations (different database engines) - **Secure**: Provides encryption in transit and at rest - **Automated**: Handles schema conversion and data type mapping - **Continuous Replication**: Can maintain synchronization between source and target databases ### Why Other Options Are Incorrect: - **AWS Snow Family**: Used for offline data transfer of large datasets, not for live database migration with minimal downtime - **AWS DataSync**: Designed for moving file system data between on-premises and AWS, not database migration - **AWS Mainframe Modernization**: Focused on modernizing mainframe applications, not general database migration AWS DMS is the ideal service for securely rehosting databases to AWS while maintaining business continuity through minimal downtime.
