Managing Terraform State and Remote Backends
Understand Terraform state, configure secure remote backends, handle state locking, and avoid state corruption in collaborative IaC pipelines.
What is Terraform State
Terraform records what it has created in a state file (terraform.tfstate). It maps your configuration to real cloud resources.
Without state, Terraform would not know which resources already exist and could create duplicates or fail to update.
Why Local State Fails Teams
By default, state lives on your local disk. That breaks down with a team or in CI:
- Others cannot see your state
- Concurrent runs corrupt the file
- The file holds secrets in plain text and could be committed by accident
The fix is a remote backend.
