Amazon Relational Database Service (Amazon RDS) is a collection of managed services that makes it simple to set up, operate, and scale databases in the cloud. Choose from seven popular engines.

1. Amazon Aurora with MySQL compatibility.
2. Amazon Aurora with PostgreSQL compatibility
3. MySQL
4. MariaDB
5. PostgreSQL
6. Oracle
7. SQL Server — and deploy on-premises with Amazon RDS on AWS Outposts

This means that the code, applications, and tools you already use today with your existing databases can be used with Amazon RDS. One of the key advantages of Amazon RDS is that it handles database management tasks, such as provisioning, patching, backup, recovery, failure detection, and repair.
