Amazon RDS :
* Broader Engine Support : Supports a wider range of database engines, including MySQL, PostgreSQL, MariaDB, Microsoft SQL Server, and Oracle.
* Customization : Offers more customization options for database configurations.
* Foundation : Built upon existing database engines.
Amazon Aurora :
* Cloud-Native : Designed specifically for the cloud, offering higher performance and scalability.
* Engine Focus : Primarily supports MySQL and PostgreSQL compatible editions.
