Amazon Aurora vs YDB

Both stand on distributed sql databases. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

Amazon Aurora

Free plan API

Choose Amazon Aurora if you need a managed relational database with PostgreSQL, MySQL, or DSQL engines and want database operations through the RDS console, CLI, or API. The free Aurora PostgreSQL Serverless plan has limited capacity and storage; paid use is usage-based, with costs depending on configuration.

YDB

YDB spans transactional, analytical and streaming use cases, with both self-hosted and cloud deployment options. Teams relying on dbt should account for the connector's Preview status and incomplete feature support.
