I mostly work with AWS, but have used Azure in the past and remember the Resource Group concept. It is quite dangerous when coupled with Terraform (or any IaC tooling for that matter).

AWS RDS has a feature where if you delete a DB instance it prompts you to take a final snapshot of the data. I haven't used Terraform in just over a year now (have been using aws-cdk), but as far as I remember, Terraform deletes of RDS instances would require you to add a 'force' argument/option to override the prompt for the final snapshot.

Something like this seems like a no-brainer for Azure SQL when deleting instances.

Also, with TF its always best to plan, write the plan output to a file, and then run apply against that plan (after having studied it!)
