Which service helps migrate a SQL Server database to AWS?

  1. DynamoDB

  2. AWS RDS

  3. Database Migration Service

  4. ElastiCache

The correct answer is: Database Migration Service

The Database Migration Service (DMS) is specifically designed to facilitate the migration of databases to AWS, including SQL Server databases. It provides the ability to migrate data with minimal downtime, enabling organizations to continue operations while the migration is in progress. DMS supports various source and target database engines, ensuring a seamless transfer of data whether you're moving from on-premises servers or other cloud services to AWS. Furthermore, it automates the process of database replication and can handle schema conversion as needed, making it a robust choice for these migration tasks. In contrast, while AWS RDS offers management services for relational databases, it doesn't handle the migration process itself. DynamoDB is a NoSQL database service and would not be suitable for migrating an SQL Server database directly. ElastiCache is primarily used for caching and enhancing the performance of applications and does not pertain to database migration capabilities. The distinct role of DMS in optimizing and managing the migration process is what makes it the correct answer for successfully migrating a SQL Server database to AWS.
