A city must migrate an on-premises Oracle database to Aurora PostgreSQL and keep data replicating until cutover. Which AWS service is designed for that database migration and replication work?
Select an answer to reveal the explanation.
Short Explanation
DMS is the moving van that can keep carrying boxes while you finish packing—the service migrates databases and can keep replicating changes until you flip the switch. CloudFront caches web content, Shield is DDoS protection, and Cognito handles user sign-in—not database moves.
Full Explanation
AWS Database Migration Service (AWS DMS) migrates databases to AWS and can sustain ongoing replication so teams minimize downtime during cutover, including heterogeneous paths such as Oracle toward Aurora PostgreSQL. Amazon CloudFront is a CDN, AWS Shield provides DDoS protection, and Amazon Cognito provides authentication and user pools—none perform database migration or continuous replication.
