AWS Database Migration Service (DMS)
AWS Database Migration Service handles the heavy lifting of moving data between different database engines, whether you’re shifting from on-premise SQL Server to Amazon RDS or consolidating multiple sources into a single cloud target. It manages the replication process to keep data synchronized during the transition, ensuring your applications stay online while the underlying infrastructure changes.
This setup works well for teams needing a managed migration path without upfront licensing costs, as the service itself operates on an always-free tier. However, the "free" label applies to the DMS engine; you still pay for the underlying compute instances and storage required to run the migration tasks, so budget for those infrastructure resources separately.
