AWS Database Migration Service (DMS)

AWS Database Migration Service handles database migrations with minimal downtime. It moves data between different database engines, keeping the source system running while data syncs in the background. This approach ensures business continuity during the transition process without requiring complex custom scripts.

The service fits teams needing straightforward, low-downtime migrations across various database types. It is always free, which removes cost barriers for small to medium projects. However, you only pay for the underlying compute and storage resources used, so large-scale migrations can still incur significant AWS infrastructure costs despite the service itself being free.
