Terraform Fundamentals

Terraform manages infrastructure declaratively with execution plans and state.

Core Concepts

• Providers and resources
• State file and backend
• Variables, outputs, and locals
• Modules for reuse

Common Workflow

terraform init
terraform fmt -recursive
terraform validate
terraform plan
terraform apply

Best Practices

• Use remote state with locking.
• Structure reusable modules.
• Enforce review for plan output before apply.
