A company wants to migrate an on-premises NoSQL workload to Amazon DynamoDB. Which AWS service is appropriate for that migration?

AWS Database Migration Service (AWS DMS) is the correct choice because it is specifically designed to help migrate databases to AWS quickly and securely. It supports homogeneous migrations (e.g., Oracle to Oracle) as well as heterogeneous migrations (e.g., Oracle to Amazon Aurora or NoSQL to Amazon DynamoDB). AWS DMS handles the complexities of data migration, allowing for minimal downtime. AWS Migration Hub provides a single location to track the progress of application migrations across multiple AWS and partner solutions, but it doesn't perform the migration itself. Migration Evaluator helps assess on-premises environments for migration planning and cost estimation, not the migration execution. AWS Application Migration Service (AWS MGN) is primarily used for rehosting (lift-and-shift) applications and servers to AWS, not specifically for database schema and data conversion like a NoSQL to DynamoDB migration requires.
