Course Outline

Module 1: Foundations of Infrastructure as Code and Terraform

  • The concept and advantages of IaC in on-premises and hybrid setups.
  • An overview of Terraform: providers, resources, state, and the resource lifecycle.
  • Setting up Terraform, Azure CLI, and other essential tools.
  • First practical exercise: creating and applying a basic Terraform configuration locally.

Module 2: HashiCorp Configuration Language (HCL) and Core Configuration

  • HCL syntax, resource definitions, attributes, and expressions.
  • Working with variables, outputs, locals, and type constraints.
  • Using the Terraform CLI for core commands: init, plan, apply, destroy, and fmt.
  • Hands-on lab: developing a parameterized configuration for both an on-prem resource and an Azure resource.

Module 3: Providers, Resources, and the Azure Provider

  • Understanding providers and configuring the AzureRM provider.
  • Translating real-world infrastructure (networking, compute, storage) into Terraform resources.
  • Handling Azure authentication and service principals for automated tasks.
  • Practical task: provisioning an Azure virtual network and a basic VM using Terraform.

Module 4: State Management, Backends, and Team Collaboration

  • The role, structure, and lifecycle of Terraform state.
  • Configuring remote backends using Azure Storage Accounts and implementing state locking.
  • Managing workspaces, environments, and collaborative workflows for teams.
  • Lab: setting up remote state in Azure Storage and executing a multi-user workflow.

Module 5: Modularization, Reusability, and Best Practices

  • Creating and utilizing Terraform modules effectively.
  • Managing module inputs, outputs, versioning, and registry usage.
  • Establishing clean folder layouts, naming conventions, and maintainable repository structures.
  • Hands-on: building a reusable module for Azure VMs, disks, and networking, and testing it across different environments.

Module 6: Managing Azure Virtual Devices and On-Prem Integration

  • Controlling Azure Virtual Machines, Virtual Desktop components, and device lifecycles via Terraform.
  • Strategies for hybrid device management: linking on-prem resources with Azure-managed devices.
  • Integrating volumetric or device management systems using data sources and external providers.
  • Lab: deploying a fleet of Azure VMs to represent operator units, including inventory tagging and basic monitoring setup.

Module 7: CI/CD, Automation, and Deployment Pipelines

  • Connecting Terraform to CI/CD tools like GitHub Actions and Azure DevOps pipelines.
  • Automating plan and apply processes using secured secrets and service principals.
  • Introducing Policy as Code (e.g., Sentinel or Open Policy Agent) and pre-deployment checks.
  • Hands-on: developing a GitHub Actions workflow to plan and apply Terraform changes in a sandbox subscription.

Module 8: Security, Secrets, and Operational Best Practices

  • Managing secrets via Azure Key Vault and preventing sensitive data leakage in state files.
  • Implementing access control, RBAC, and least-privilege principles for automation accounts.
  • Techniques for drift detection, state reconciliation, and basic remediation.
  • Checklist for backup, auditing, and governance of Terraform-managed infrastructure.

Module 9: Testing, Debugging, and Troubleshooting

  • Debugging Terraform configurations and interpreting plan diffs accurately.
  • Approaches to unit and integration testing using tools like terraform validate, tflint, and kitchen-terraform.
  • Identifying common error patterns and strategies for resolution.
  • Lab: running validation and linting tools to identify and fix configuration issues.

Module 10: Capstone Project — Hybrid Deployment Scenario

  • Design exercise: planning an on-prem + Azure device deployment using previously learned patterns.
  • Implementing core components with modules, remote state, and CI/CD pipeline snippets.
  • Presenting the solution, discussing trade-offs, and reviewing the operational runbook.
