What it does
Terraform is an infrastructure-as-code tool that compares declared configuration with real infrastructure and applies the proposed changes. The AWS tutorial starts with a configuration directory, provider authentication, initialization, a plan, and an apply. It is useful for repeatable provisioning, but the operator remains responsible for reviewing changes and protecting credentials and state.
Use the AWS getting-started tutorial to create a small configuration for a test environment. Authenticate the provider, initialize the working directory, inspect the proposed plan, and apply only after reviewing what will be created or changed. The plan is the key checkpoint: it makes resource changes visible before Terraform sends them to the provider.
Keep configuration and state handling deliberate. A checked-in configuration can be reviewed with the application code, while a team may choose a remote state and hosted workflow for collaboration. Terraform’s tutorial documents the CLI workflow; the separate HCP Terraform pricing route was rate-limited during research, so this listing leaves hosted-plan pricing unresolved and does not infer a free or paid tier.
Strengths
- The official tutorial covers initialization, planning, and applying cloud infrastructure.
- A plan is shown before changes are applied.
Watch out for
- Applying a plan can create or alter cloud resources, so review the proposed changes and protect provider credentials.
Best for
- Provisioning repeatable cloud infrastructure from versioned configuration
- Reviewing proposed infrastructure changes before applying them
