Terraform is a powerful tool that allows infrastructure teams to manage entire datacenters with just a few lines of configuration code, making it versionable, reproducible, and predictable. Aiven has developed its own Aiven Terraform Provider for managing open source data infrastructure. In this tutorial, we will learn how to use Terraform to configure an Aiven account, set up the Aiven Provider, and deploy a PostgreSQL database on GCP. It is important to note that Terraform can be very picky about the resources it manages, so avoid changing them manually through other tools like the Aiven Console or CLI.
