## TL;DR

Infrastructure as Code manages cloud and infrastructure resources through versioned configuration and templates. This repair maps IaC claims to Terraform, CloudFormation, and Pulumi sources.

## Core Explanation

The sampled article had low source coverage and generic dispute text. This version keeps three bounded facts about declarative configuration, templates, and general-purpose IaC programs.
