# RDS Option Group

An RDS Option Group in AWS allows you to enable and manage additional features for Amazon RDS instances that are not available by default. These options can include features like Oracle Transparent Data Encryption, SQL Server Audit, or advanced monitoring tools. By assigning an option group to a database instance, you can customize its functionality without changing the underlying database engine.

```
aws.rds_option_group
```
