Course Outline

Module 1: Introduction to Infrastructure as Code and Terraform

  • The core concepts of IaC and their advantages within on-premises and hybrid landscapes
  • An overview of Terraform, covering providers, resources, state management, and the resource lifecycle
  • Installation procedures for Terraform, Azure CLI, and other necessary utilities
  • Initial practical exercise: drafting a basic Terraform configuration and executing it locally

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

  • Details on HCL syntax, including resources, attributes, and expression usage
  • Defining variables, outputs, locals, and enforcing type constraints
  • Operating the Terraform CLI: commands for init, plan, apply, destroy, and fmt
  • Practical lab: constructing a parameterized configuration for both an on-prem resource and an Azure resource

Module 3: Providers, Resources, and Azure Provider Fundamentals

  • Gaining insight into providers and configuring the AzureRM provider
  • Mapping physical infrastructure to Terraform resources across networking, compute, and storage
  • Handling Azure authentication and setting up service principals for automated tasks
  • Practical task: provisioning an Azure virtual network and a basic VM through Terraform

Module 4: State Management, Backends, and Collaboration

  • Understanding Terraform state: its purpose, structure, and lifecycle implications
  • Utilizing remote backends via Azure Storage Accounts and implementing state locking strategies
  • Managing workspaces, environments, and establishing collaboration workflows for teams
  • Lab exercise: 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
  • Defining module inputs/outputs, managing versions, and applying registry patterns
  • Establishing folder layouts, naming conventions, and maintaining a well-structured repository
  • Practical exercise: developing a reusable module for an Azure VM with disk and network components, and testing it across various environments

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

  • Overseeing the lifecycle of Azure Virtual Machines, Virtual Desktop components, and other devices 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 exercise: deploying a fleet of Azure VMs representing operator units, including inventory tagging and basic monitoring setup

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

  • Connecting Terraform with CI/CD tools such as GitHub Actions and Azure DevOps pipelines
  • Automating plan and apply processes while securing secrets and managing service principals
  • Introducing Policy as Code basics, such as Sentinel or Open Policy Agent patterns, and implementing pre-deployment checks
  • Practical exercise: building a simple GitHub Actions workflow to plan and apply Terraform against a sandbox subscription

Module 8: Security, Secrets, and Operational Practices

  • Handling secrets through Azure Key Vault integration and preventing sensitive data leakage in state files
  • Implementing access controls, RBAC, and least privilege principles for automation accounts
  • Performing drift detection, state reconciliation, and basic remediation tasks
  • Reviewing a checklist for backup, auditing, and governance of Terraform-managed infrastructure

Module 9: Testing, Debugging, and Troubleshooting

  • Diagnosing Terraform configurations and interpreting plan diffs with precision
  • Applying unit and integration testing methods using tools like terraform validate, tflint, and kitchen-terraform
  • Identifying common error patterns and developing effective resolution strategies
  • Lab exercise: executing validation and linting tools and correcting identified issues

Module 10: Capstone Project — Hybrid Deployment Scenario

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