You’ll use the Terraform CLI locally as well as optionally Terraform Cloud. If you don’t have the Terraform CLI installed on your computer, see the instructions here.
Terraform Cloud (TFC) is a self-service SaaS platform that extends the capabilities of the open source Terraform CLI. It’s free for basic usage, but we’ll be leveraging advanced features, such as Sentinel, that will require a paid subscription or trial. Sign up for Terraform Cloud here and log in using your CLI.
