Terraform lets you describe your cloud infrastructure in code and apply it reproducibly. This series is AWS-oriented: every example creates real resources — VPCs, EC2 instances, load balancers, RDS databases — that you can destroy with a single command at the end of each lab.

You begin with the workflow (init, plan, apply, destroy), the structure of a configuration file, providers and resources, and remote state stored on S3. The language chapters then cover variables, locals, outputs, data sources, conditional expressions, dynamic blocks and the two loop constructs, count and for_each.

The infrastructure chapters assemble those bricks into production patterns: EBS volumes, ELB, IAM, RDS, Route 53, autoscaling groups, and a full VPC written first without and then with modules. The Modules lesson — the longest of the series — shows how to design, version and reuse your own modules.

Prerequisites: an AWS account with programmatic access and the AWS CLI configured. Terraform 1.x is assumed; where syntax changed across versions, the lesson tells you.
