Clicking through a cloud console to spin up servers works fine once — it falls apart the moment you need to do it again reliably, in a different region, or after a teammate accidentally changes a setting by hand. This module covers Infrastructure as Code with Terraform: describing infrastructure declaratively with providers and resources, and how Terraform's state tracks what it has already created.
It also covers organizing configurations into reusable modules, storing state safely in remote backends, separating environments with workspaces, and a first look at configuration management with Ansible for configuring the servers Terraform provisions.
Watch the lessons in order, then continue on to Cloud Providers.
The problems with manually clicking through a console — drift, inconsistency, no history — and how treating infrastructure as code fixes them.
The core Terraform workflow — write, plan, apply — and how providers and resources map to real infrastructure, tracked in a state file.
HCL syntax, variables, outputs, and structuring a project's .tf files so they stay readable as infrastructure grows.
Packaging common infrastructure patterns into modules so teams stop copy-pasting the same resource blocks across projects.
Why local state files are risky for teams, and storing state remotely with locking to prevent conflicting changes.
Managing dev, staging, and production from the same configuration using workspaces and variable-driven environment separation.
Using Ansible playbooks to configure servers after they're provisioned — installing packages, managing files, and enforcing consistent state.
Keeping configurations reviewable through pull requests, detecting when real infrastructure drifts from what's declared, and reconciling it safely.
A written reference covering Terraform syntax, core commands, and module structure from this module — good for a quick lookup after watching the videos.
