A company wants to securely rehost databases to AWS with minimal downtime. Which AWS service will meet these requirements?
A
AWS Database Migration Service (AWS DMS)
B
AWS Snow Family
C
AWS DataSync
D
AWS Mainframe Modernization
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:
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
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.
