What is the benefit of implementing Terraform workspaces?

Implementing Terraform workspaces offers the key benefit of managing different states for different environments, which is critical for maintaining organized and scalable infrastructure management. Each workspace can hold a separate state file, enabling you to work on different versions of your infrastructure simultaneously, such as development, testing, and production environments, while isolating configurations and resources relevant to each stage.

This separation reduces the risk of unintended changes affecting other environments and allows teams to deploy and manage multiple infrastructure setups efficiently. By using workspaces, you can also switch between different configurations easily, which is particularly beneficial in CI/CD pipelines or during multi-environment deployments.

The other choices do not directly relate to the core functionality and advantages offered by workspaces within Terraform. While coding and documentation have their own importance in the IaC practice, they are not specifically enhanced by the use of workspaces, nor does using workspaces inherently increase execution speed.
