Terraform
Also known as: Terraform / テラフォーム
HashiCorp's Infrastructure as Code (IaC) tool. Using HCL, it declaratively defines cloud resources and manages consistent infrastructure provisioning and changes across AWS, GCP, Azure, Cloudflare, and many other providers.
Overview
Terraform previews infrastructure changes with `terraform plan` and applies them with `terraform apply`. Storing configuration in Git makes infrastructure changes subject to code review and CI/CD pipelines. An OSS fork called OpenTofu also exists.
Multi-Cloud Management
Terraform manages AWS, GCP, Azure, Cloudflare, and other providers with a single tool, making it ideal for consistent IaC across multi-cloud environments. See cloud migration guide.
