Which AWS service is designed to automate the migration of databases to the AWS cloud?
a) AWS Database Migration Service (DMS)
b) Amazon RDS
c) Amazon Redshift
d) AWS Lambda
Answer:
a) AWS Database Migration Service (DMS)
Explanation:
AWS Database Migration Service (DMS) helps users migrate databases to the AWS cloud with minimal downtime. DMS supports homogeneous migrations (e.g., MySQL to MySQL) as well as heterogeneous migrations (e.g., Oracle to Amazon Aurora).
DMS continuously replicates data from the source to the target database, ensuring a smooth transition with little disruption to applications. It also supports data transformation and schema conversion during the migration process.
This service is widely used for moving on-premises databases or databases from other cloud providers to AWS, simplifying the process of cloud migration.
