A team migrating a self-hosted PostgreSQL database to AWS wants minimal downtime, ongoing replication during the cutover, and a target like Amazon RDS or Aurora PostgreSQL. Which AWS service is purpose-built for this?
AAWS Glue
BAWS Database Migration Service (AWS DMS)
CAmazon QuickSight
DAWS Snowball Edge
Answer & Solution
Correct answer: B. AWS Database Migration Service (AWS DMS)
DMS handles continuous replication from source to target during a migration so the application can keep running until cutover. Snowball Edge is for bulk offline data transfer. QuickSight is BI dashboards. Glue is an ETL service.
