If the number of data sources becomes large, consider moving them to a version constraint For root modules, provide variables by using a .tfvars variables file. See best practice for multi-Region deployments using HashiCorp #terraform, and AWS CodeBuild, CodePipeline as CI/CD for consistency and repeatability of deployments into multiple AWS Regions and AWS Accounts. In my previous post, Deploying Multiple Environments with Terraform, I described how I used Terraform to deploy to multiple environments within a single project. In the cases where this is truly a problem (large root modules, and/or many regions across many environments), there are tools that can handle this effectively for you. For shared modules, define the minimum required provider versions in a By default, a file with a name terraform.tfstate.backup will get created to keep a backup of the state file.
