What is the purpose of a Terraform workspace?

A Terraform workspace is a mechanism that allows you to manage multiple states for different environments or deployments within the same configuration. By using workspaces, you can keep separate state files for different instances of your infrastructure, which is particularly useful for managing different environments like development, staging, and production. This enables you to deploy your resources in isolation from one another while using the same Terraform configuration.

When you create a new workspace, a new state file is created, allowing you to make changes specific to that workspace without affecting others. This makes it easier to manage your infrastructure and tailor your deployments to the needs of each environment. It essentially helps in organizing infrastructure resources and tracking changes separately.

The other options provided, while they may relate to broader Terraform functionality or practices, do not directly pertain to the specific role of workspaces in isolating state files for different environments. Thus, the primary purpose of a Terraform workspace is to manage collections of infrastructure in state files, which is why this choice is accurate.
