1.2.4. 💡 First Principle: Infrastructure as Code (IaC)

First Principle: Treating infrastructure like application code enables automation, versioning, and consistent environments.

Infrastructure as Code (IaC) transforms manual, error-prone infrastructure management into automated, repeatable, and auditable processes, ensuring a desired state and reducing configuration drift and human error.

Scenario: An operations team manually provisions servers and network configurations for every new application environment. This process is slow, inconsistent, and prone to human error.

Reflection Question: How does adopting Infrastructure as Code (IaC) fundamentally address the challenges of inconsistency and manual errors in infrastructure management, and what are the long-term benefits for a DevOps team?

💡 Tip: Consider the challenges of manually managing infrastructure (e.g., inconsistent environments, slow provisioning). How does IaC directly address these?
