Terraform is an open source "Infrastructure as Code" tool, used by DevOps and SysOps engineers to codify their cloud infrastructure requirements.
In this course you'll learn about Terraform from the ground up, and how it can be used to codify infrastructure. Terraform can be used to provision infrastructure across multiple cloud providers including AWS which this course will focus on.

Welcome back. In this lesson, I'll review the installation process for installing the open-source version of Terraform locally. Now the good news is since Terraform is packaged as a single binary, installation is very simple and quick, as you'll soon see. Let's begin.
Terraform provides operating system specific downloads for all of the most popular desktop or workstation operating systems, including macOS, Linux, and Windows. Clicking on any of the provided download links will download a ZIP archive. Once downloaded, it is just a case of unzipping the archive and then moving the single Terraform executable binary within to a location configured on your operating system's system PATH. It's literally that easy.
Now if you're looking for a more automated or scripted approach for a macOS-based system, then the following script displayed here can be used to download and install the latest version of the Terraform CLI, hands-off. The script provided on the screen is specific to macOS. This script will also set up autocompletion for the Terraform subcommands. Likewise, for Linux, this script can, again, be used to install the latest version of Terraform CLI automatically. And for Windows, the process provided here is a bit more manual, but in a sense, just requires you to move the Terraform binary to a location, as previously mentioned, configured in the current system PATH environment variable.
