Terraform is an infrastructure-as-code tool developed by HashiCorp, designed to manage and provision cloud resources through a unified configuration language, HCL (HashiCorp Configuration Language). It streamlines the process of setting up and maintaining infrastructure across multiple cloud providers. In 2023, HashiCorp's shift to a BUSL-1.1 license led to the creation of OpenTofu, an open-source fork maintained by the Linux Foundation, which has gained popularity for new projects seeking open-source continuity. Key concepts in Terraform include state management, particularly concerning remote backends and state locking, as well as designing modular and composable code structures.
