Which AWS service will meet these requirements?

Explanations:

Amazon EMR is a managed service primarily for big data processing using frameworks like Apache Hadoop and Spark. It is not specifically designed for MySQL databases.

Amazon RDS (Relational Database Service) is a managed service that simplifies the setup, operation, and scaling of relational databases, including MySQL. It automates tasks such as backups, patching, and scaling, making it ideal for MySQL in the AWS Cloud.

Amazon Redshift is a managed data warehouse service optimized for analytics and not for traditional relational database operations like MySQL. It is intended for OLAP (Online Analytical Processing) rather than OLTP (Online Transaction Processing).

Amazon DynamoDB is a managed NoSQL database service, which is not compatible with MySQL. It is designed for key-value and document data structures, focusing on high availability and scalability but not on traditional SQL operations.
