For an introduction to using\nTerraform with Google Cloud, see\n[Get started with Terraform](/docs/terraform/get-started-with-terraform).\n\nA common problem that arises when using Terraform is how to share information\nacross different Terraform configurations (possibly maintained by different\nteams). Generally, information can be shared between configurations without\nrequiring that they be stored in a single configuration directory (or even a\nsingle repository).\n\nThe recommended way to share information between different Terraform\nconfigurations is by using remote state to reference other root modules.\n[Cloud Storage](https://www.terraform.io/docs/backends/types/gcs.html)\nor\n[Terraform Enterprise](https://www.terraform.io/docs/backends/types/terraform-enterprise.html)\nare the preferred state backends.\n\nFor querying resources that are not managed by Terraform, use data sources from\nthe\n[Google provider](https://registry.terraform.io/providers/hashicorp/google/latest/docs).\nFor example, the default Compute Engine service account can be retrieved\n[using a data source](https://registry.terraform.io/providers/hashicorp/google/latest/docs/data-sources/compute_default_service_account).\nDon't use data sources to query resources that are managed by another Terraform\nconfiguration. Doing so can create implicit dependencies on resource names and\nstructures that normal Terraform operations might unintentionally break.\n\nWhat's next\n-----------\n\n- Learn about [best practices for version control](/docs/terraform/best-practices/version-control).\n- Learn about [best practices when working with Google Cloud resources](/docs/terraform/best-practices/working-with-resources)."]]
