Many Terraform beginners assume a workspace creates a separate environment.
The reality is more nuanced.
A workspace creates a separate state file. AWS still evaluates resource names, credentials, and account boundaries independently of Terraform state.
In this lesson, we walk through the practical controls that make workspaces safe to use. We examine naming boundaries, default workspace risks, configuration mapping, resource traceability, and IAM separation.
One of the most important takeaways is that workspaces solve a state isolation problem. They do not solve an authorization problem.
Understanding that distinction helps prevent environment collisions, permission mistakes, and deployment errors as infrastructure grows.
