Many Terraform beginners assume a workspace named prod automatically means production safety.
Terraform does not work that way.
A workspace changes which state file Terraform uses. It can also influence configuration through terraform.workspace. What it does not change is AWS authentication, account selection, or backend permissions.
That distinction matters because a production workspace can still deploy into the wrong AWS account if credentials are misconfigured.
In this lesson, we break down the actual mechanics of workspaces, how state isolation works, how workspace-driven inputs are evaluated, and why account verification should always remain a separate control.
Understanding this boundary helps prevent one of the most common misconceptions in Terraform operations:
Workspace names are labels. AWS accounts are boundaries.
