Which databases is AWS Aurora compatible with?

AWS Aurora is designed as a relational database service that is compatible with MySQL and PostgreSQL. This compatibility allows developers and database administrators to use existing tools, libraries, and applications built for these open-source databases with minimal or no changes. It provides a high-performance, highly available, and easily scalable solution while supporting the same query languages and APIs as MySQL and PostgreSQL.

By being compatible with these two widely used relational databases, AWS Aurora enables organizations to leverage the benefits of Amazon's cloud infrastructure without having to rework their existing schema or rewrite application code that interacts with the database. This makes migration to Aurora a more seamless process for teams already using MySQL or PostgreSQL in their applications.
