Infrastructure as Code
Infrastructure as Code tools and building blocks: Terraform, OpenTofu, Terragrunt, state, modules, providers, HCL, CloudFormation, linters and cost estimation.
Infrastructure as Code
AWS CloudFormation
AWS CloudFormation is the native infrastructure as code service of AWS: describe resources in JSON or YAML templates and it manages them as stacks.
Infrastructure as Code
Packer
Packer is a HashiCorp tool that builds identical machine images, such as AWS AMIs and Docker images, from a single configuration file.
- Infrastructure as Code
HCP Terraform
HCP Terraform (formerly Terraform Cloud) is the HashiCorp managed service that stores state, runs plans remotely and applies policies for teams.
- Infrastructure as Code
Pulumi
Pulumi is an infrastructure as code tool where you describe cloud resources in general-purpose languages such as TypeScript, Python and Go.
Infrastructure as Code
OpenTofu
OpenTofu is the open-source, Linux Foundation fork of Terraform for Infrastructure as Code, compatible with Terraform providers and HCL.
- Infrastructure as Code
TFLint
TFLint is a linter for Terraform and OpenTofu that finds errors, deprecated syntax and invalid provider values before you run plan or apply.
- Infrastructure as Code
Infracost
Infracost estimates the monthly cost of Terraform and OpenTofu changes and shows the difference in pull requests before you deploy.
- Infrastructure as Code
Terragrunt
Terragrunt is a thin wrapper for Terraform and OpenTofu that keeps configuration DRY across many environments, accounts and regions.
- Infrastructure as Code
Terraform
Terraform is an infrastructure as code tool by HashiCorp that creates and changes cloud resources from declarative configuration files.
- Infrastructure as Code
Configuration Drift
Configuration drift is the difference between the real infrastructure and its Terraform code or state, caused by manual changes. Learn how to detect and fix it.
- Infrastructure as Code
Terraform Backend
A Terraform backend defines where the state is stored and how operations run. Learn the S3 backend, locking and how to migrate between backends.
- Infrastructure as Code
Terraform Workspace
A Terraform workspace is a named state inside the same backend and configuration, used to create several copies of an infrastructure.
- Infrastructure as Code
Terraform State
The Terraform state is the file where Terraform and OpenTofu record which real resources they manage, so they can plan and apply changes.
- Infrastructure as Code
Terraform Module
A Terraform module is a reusable set of resources in a directory, with input variables and outputs. Learn how modules work in Terraform and OpenTofu.
- Infrastructure as Code
Terraform Provider
A Terraform provider is a plugin that lets Terraform and OpenTofu manage resources of a platform such as AWS, Azure or Kubernetes through its API.
- Infrastructure as Code
Terraform Built-in Functions
Terraform functions perform specific tasks on configuration data: numeric, string, collection, date and time, file system and more.
- Infrastructure as Code
HCL
HCL is a domain-specific language developed by HashiCorp, a company known for its infrastructure automation tools such as Terraform, Vault, Consul, and Nomad.
