A Practical Guide

Manage infrastructure the way you manage code: reviewed, tested, repeatable, and safe.

Clicking through cloud consoles works — until you need a second environment, someone changes production by hand, or nobody remembers why a setting exists. This book teaches Terraform and the discipline of Infrastructure as Code from the ground up, and goes all the way to the practices real platform teams rely on: remote state, reusable modules, multi-account environments, testing, policy as code, and CI/CD pipelines. You learn by building the infrastructure of Fieldmark, a fictional agriculture-technology platform, from a single bucket to a complete multi-environment system.
