About Terraform
Terraform made cloud infrastructure reviewable: declare resources in HCL, plan the diff, apply, and your AWS, Azure, and GCP estate lives in version control. Thousands of providers cover nearly every API. The 2023 BSL license change spawned the OpenTofu fork and IBM later acquired HashiCorp, yet Terraform remains the enterprise default with state management its crown jewel.
