Which AWS service can help you migrate databases to AWS?

The AWS Database Migration Service (DMS) is specifically designed to facilitate the migration of databases to AWS. It supports a wide variety of source and target database engines, allowing users to easily and securely transfer data with minimal downtime. DMS can help with both homogeneous migrations (where the source and target databases are of the same type) and heterogeneous migrations (where the source and target databases differ).

DMS provides features such as continuous data replication to keep your databases synchronized during the migration process, ensuring that your applications can run smoothly with minimal interruptions. Additionally, it automates much of the migration process, reducing the complexity and time involved in moving databases to AWS. This service is an essential tool for any organization looking to migrate their databases to the AWS cloud environment efficiently.

The other services listed have different primary purposes. Elastic Beanstalk is primarily focused on deploying applications rather than managing database migrations. CloudFormation is used for provisioning and managing AWS infrastructure as code but does not specifically address database migration tasks. Snowball is a service for transferring large amounts of data to and from AWS, primarily for scenarios where network transfer is impractical due to size but not specifically tailored towards database migrations.
