Terraform – Infrastructure as Code

Provision infrastructure declaratively with HCL, reviewed plans, and protected state.

Practice interactively →

What you will learn

• Explain declarative IaC and immutable patterns
• Distinguish Terraform provisioning from Ansible configuration
• Perform init, plan, apply, and state operations
• Use variables, data sources, outputs, and modules

Lessons

1. Infrastructure as Code

   Manage infrastructure as versioned, reviewable code.

2. Terraform, HCL, and Ansible

   Choose tools by lifecycle instead of forcing one tool to do everything.

3. Workflow and state

   Review execution plans and protect state as critical operational data.

4. Variables, outputs, data sources, and modules

   Design HCL interfaces and reuse code without hiding dependencies.

5. Terraform with AWS

   Model network dependencies and use credentials without hard-coding them.
