A company needs to migrate a PostgreSQL database from on-premises to Amazon RDS.
Which AWS service or tool should the company use to meet this requirement?
Cloud Adoption Readiness Tool
AWS Migration Hub
AWS Database Migration Service (AWS DMS)
AWS Application Migration Service
Explanations:
Cloud Adoption Readiness Tool helps assess cloud readiness but does not facilitate database migrations.
AWS Migration Hub provides a central place to track migrations but does not perform the migration itself.
AWS Database Migration Service (AWS DMS) is designed for migrating databases, including PostgreSQL, to AWS.
AWS Application Migration Service focuses on migrating applications, not specifically databases.
I arrange that the answer is:
AWS Database Migration Service (AWS DMS)
