Introduction to IaC and Terraform
Explore the principles of Infrastructure as Code (IaC) and understand how Terraform fits into modern cloud infrastructure management.
Introduction to IaC and Terraform is a free DevOps Bootcamp lesson on CoddyKit — lesson 1 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the DevOps Bootcamp learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
What is Infrastructure as Code?
Infrastructure as Code (IaC) means managing servers, databases, and networks with code and dev practices — not manual clicking through consoles.
Why Use IaC?
IaC pays off fast: consistent environments, faster provisioning, version control with rollbacks, and far fewer manual misconfigurations.
Manual vs. IaC Approach
Setting up a server by hand means logging in and clicking through menus each time. With IaC, you write the config once and reproduce identical servers automatically.
Introducing Terraform
Terraform, HashiCorp's open-source IaC tool, lets you define cloud and on-prem resources in human-readable files and manage their whole lifecycle.
How Terraform Fits IaC
Terraform delivers IaC by letting you declare your desired resources, work across many cloud providers, and track everything through state.
Declarative vs. Imperative
Terraform is declarative: you describe what you want, not the steps to get there. It figures out how to reach that desired state for you.
Terraform's High-Level Workflow
The Terraform loop is three commands: init sets up the directory, plan previews changes, and apply makes them real. We'll go deeper soon.
Terraform's Configuration Language
Terraform configs use HCL (HashiCorp Configuration Language) — JSON-like but far more readable, with blocks for providers, resources, and variables.
Your First Terraform Snippet: Provider
Every config starts with a provider, telling Terraform which cloud to talk to. Here's the AWS provider declared.
terraform {
required_providers {
aws = {
source = "hashicorp/aws"
version = "~> 5.0"
}
}
}
provider "aws" {
region = "us-east-1"

Recap: IaC & Terraform Intro
Recap: you met IaC and its benefits, saw why Terraform leads, grasped its declarative style, and glimpsed HCL and the provider block. Next: installing the CLI.
