tofu (OpenTofu) is an open-source infrastructure-as-code tool forked from Terraform, allowing you to define cloud and on-premises resources in declarative HCL configuration files. It supports major cloud providers including AWS, GCP, and Azure through a provider plugin system.The workflow follows an init-plan-apply cycle: init downloads providers and modules, plan previews proposed changes, and apply creates or modifies the actual infrastructure. State is tracked in a state file that maps configuration to real resources, enabling incremental updates and safe destruction with destroy.
