Explanation
Amazon Relational Database Service (RDS) is the AWS service that supports MySQL database engines, as well as several other popular relational databases like PostgreSQL, MariaDB, Oracle, and Microsoft SQL Server.
With Amazon RDS, you can quickly and easily set up, operate, and scale MySQL deployments in the cloud. RDS automates time-consuming administration tasks like hardware provisioning, database setup, patching, and backups. It provides cost-efficient and resizable capacity while managing your database infrastructure, freeing you to focus on your applications and business.
RDS offers several features to enhance the reliability and performance of your MySQL databases, including:
- Multi-AZ deployments for enhanced availability and durability
- Read replicas for improved read performance and faster recovery
- Automated backups and database snapshots for disaster recovery
- Automatic host replacement if issues are detected with the underlying hardware
- Encrypted storage for data security
- Easy scaling of compute and storage resources as your needs change
By leveraging the managed database services of Amazon RDS, you can deploy scalable MySQL databases in the cloud without the operational overhead of managing your own database infrastructure. The other options listed do not support MySQL:
- Amazon DynamoDB is a fully managed NoSQL database service
- Amazon DocumentDB is a document database service that is compatible with MongoDB
- Amazon ElastiCache is an in-memory caching service that supports Redis and Memcached
So in summary, Amazon RDS is the correct and only choice listed for running MySQL database engines on AWS in a managed, scalable, and highly available way.
