Question

A small operations team currently provisions cloud environments by hand, following a lengthy wiki runbook. Each new environment (dev, staging, prod) is supposed to be identical, but the team repeatedly finds subtle differences—an unopened firewall port here, a mismatched instance size there—that cause bugs to appear in production but not in staging. Management asks how adopting Infrastructure as Code would most directly address this specific problem. What is the best answer?

Accepted Answer

IaC defines environments in code that can be applied identically each time, eliminating the manual variation between environments.

Answer

IaC automatically detects security vulnerabilities in the operating system and patches them before provisioning.

Answer

IaC removes the need for staging and production environments by testing everything in a single shared environment.

Answer

IaC reduces cloud costs by automatically selecting the cheapest available instance types for each environment.
