How Terraform Works
Terraform streamlines infrastructure provisioning by treating cloud resources as code written in HashiCorp Configuration Language (HCL). Users define resources, providers, variables, and modules in .tf files, then run terraform plan to preview changes against the current state. After approval, terraform apply executes the plan, updating a centralized state file that tracks real‑world resources. The tool’s modular, multi‑cloud design lets teams scale from single‑instance tests to enterprise‑wide deployments across AWS, Azure, GCP, and dozens of other providers.
