How to install Terraform on Ubuntu 20.04

Terraform is an open-source infrastructure as code software tool that provides a consistent CLI workflow to manage hundreds of cloud services. Terraform codifies cloud APIs into declarative configuration files.

In this tutorial, we are going to learn how to install Terraform on Ubuntu 20.04.

Infrastructure as code (IAC) tools allow you to manage your infrastructure with a configuration file rather than through a graphical interface. IAC allows you to build, change and manage your infrastructure in a safe, consistent, and repeatable way by defining configurations that you can version, reuse and share.

Advantages of Using Terraform

  • Terraform can manage infrastructure on multiple cloud platforms.
  • The human-readable form helps you write infrastructure code quickly.
  • Terraforms state helps you to track resource changes throughout your deployments.
  • You can commit your configurations to version control to safely collaborate on infrastructure.
