Terraform is an Infrastructure as Code (IaC) tool developed by HashiCorp that enables teams to provision, manage, and version infrastructure using code. Instead of manually configuring resources through graphical interfaces, Terraform automates infrastructure deployment with reusable and declarative configuration files, ensuring consistency, scalability, and repeatability across on-premises and cloud environments.
