What is Terraform?

Terraform is an open-source infrastructure as code, software tool created by HashiCorp. It enables users to define and provision data center infrastructure using a declarative configuration language known as HashiCorp Configuration Language (HCL), or optionally JSON.

Terraform is a tool that allows programmers to build, change, and version infrastructure safely and efficiently.

Terraform’s main job is to create, modify, and destroy servers and other resources.

Terraform does not configure servers software. Configuring software can be performed with scripts, configuration management tools or container deployments.

The basic workflow when using Terraform is:

  • Write the configuration files on your computer in which you declare the elements of your infrastructure that you want to create.
  • Tell Terraform to analyze your configurations and then create the corresponding infrastructure.
