Terraform is an open-source software tool that converts configuration files known as HCL (Hashicorp Configuration Language) into real-world infrastructure, usually in Cloud providers such as AWS, Azure, or Google Cloud Platform. Terraform writes infrastructure as code (IaC) to manage public (or private) cloud data. When infrastructure gets defined by writing it in code, it allows for team collaboration, historical documentation of changes made to the infrastructure, and the ability to redeploy the infrastructure wherever necessary. The two declarative configuration languages that Terraform users manage data with are either HCL or JSON. Terraform developers can expect a software tool that provides a consistent command-line interface (CLI) workflow to manage hundreds of cloud services and automate infrastructure tasks. Programmers can download and run Terraform on one machine.
