What is Terraform?

Terraform is an open-source Infrastructure as Code (IaC) tool developed by HashiCorp that enables users to provision, manage, and version infrastructure using a declarative configuration language called HashiCorp Configuration Language (HCL). It supports a wide range of service providers—including AWS, Azure, Google Cloud, and many others—allowing teams to manage multi-cloud and hybrid environments in a consistent way. Terraform also maintains a state file to track infrastructure changes over time, which helps with planning and applying updates safely and predictably.
