Infrastructure as Code¶
DevOps practices and IaC tooling for defining, validating, and deploying infrastructure through code — enabling consistent, repeatable, and auditable infrastructure management.
Popular IaC Tools¶
Terraform — An open-source declarative tool that offers pre-written modules to build and manage infrastructure.
Ansible — Used for building infrastructure and deploying and configuring applications. Best for ad-hoc operations.
Packer — Generates VM images based on steps you provide. Best for baking compute images.
Vagrant — Builds VMs using a workflow. Best for pre-configured developer VMs in VirtualBox.
