IaC
Infrastructure as Code
Managing infrastructure through machine-readable definition files.
Infrastructure as code defines servers, networks, and policies in version controlled, machine readable files so environments are provisioned consistently and repeatably rather than by manual clicks. It reduces configuration drift, enables peer review, and supports rapid, auditable rebuilds. It matters for secure, reproducible deployments and immutable infrastructure. The main pitfall is that mistakes and embedded secrets propagate at scale, so templates need scanning, secret management, and least privilege; hard coding credentials in a repository is a frequent and serious error.
Looking IaC up is step one. Getting tested on it is step two.
