**MySQL** is a relational database used by many web applications. On AWS it runs in [RDS](https://www.itwonderlab.com/aws-rds/) and [Aurora](https://www.itwonderlab.com/aws-aurora/). [MariaDB](https://www.itwonderlab.com/mariadb/) is a compatible fork.

### Key concepts

- **InnoDB**: the default storage engine.
- **Replication**: copies data to read replicas.

### Learn it

See [MariaDB on RDS with Terraform](https://www.itwonderlab.com/terraform-aws-mariadb-rds-database/).

Run it with [Install MariaDB or MySQL with Docker](https://www.itwonderlab.com/install-mariadb-docker/).
