A company plans to migrate a relational database to Amazon RDS for MySQL. They need to minimize downtime during the migration. The source database is running on-premises. Which strategy should they use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Database Migration Service (DMS) with ongoing replication.
AWS DMS with ongoing replication allows the source database to remain operational during migration, minimizing downtime. Option B is incorrect because AWS Snowball is designed for large-scale offline data transfer, not for ongoing replication to minimize downtime. Option C is incorrect because mysqldump requires taking a backup which causes downtime during the export/import process. Option D is incorrect because a read replica can only be created from a source that is already in RDS, not from an on-premises database.
