Course Outline

Module 1: Introduction to Infrastructure as Code and Terraform

  • Core IaC concepts and their strategic benefits for on-premises and hybrid setups
  • Overview of Terraform: exploring providers, resources, state, and the lifecycle
  • Installation guide for Terraform, Azure CLI, and necessary supporting tools
  • Practical first step: authoring a simple Terraform configuration and applying it locally

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

  • Deep dive into HCL syntax, resources, attributes, and expressions
  • Working with variables, outputs, locals, and enforcing type constraints
  • Essential Terraform CLI commands: init, plan, apply, destroy, and fmt
  • Hands-on lab: constructing a parameterized configuration for both an on-prem resource and an Azure resource

Module 3: Providers, Resources, and Azure Provider Fundamentals

  • Understanding the role of providers and configuring the AzureRM provider
  • Mapping physical and virtual infrastructure to Terraform resources (networking, compute, storage)
  • Managing Azure authentication and setting up service principals for secure automation
  • Practical exercise: provisioning an Azure virtual network and a basic VM using Terraform

Module 4: State Management, Backends, and Collaboration

  • Understanding Terraform state: its purpose, format, and lifecycle implications
  • Implementing remote backends using Azure Storage Accounts and state locking strategies
  • Utilizing workspaces and environments to establish effective team collaboration patterns
  • Lab: configuring remote state in Azure Storage and executing a multi-user workflow

Module 5: Modularization, Reusability, and Best Practices

  • Techniques for authoring and consuming Terraform modules effectively
  • Managing module inputs/outputs, versioning strategies, and registry patterns
  • Establishing folder layouts, naming conventions, and maintainable repository structures
  • Hands-on: creating a reusable module for an Azure VM with disk and network, then testing it across environments

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

  • Controlling Azure Virtual Machines, Virtual Desktop components, and device lifecycles via Terraform
  • Patterns for hybrid device management: bridging on-premises resources with Azure-managed devices
  • Integrating volumetric or device management systems through data sources and external providers
  • Lab: deploying a fleet of Azure VMs representing operator units, along with inventory tagging and basic monitoring setup

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

  • Integrating Terraform into CI/CD workflows (e.g., GitHub Actions, Azure DevOps pipelines)
  • Automating plan/apply processes while securing secrets and utilizing service principals
  • Intro to Policy as Code (using Sentinel or Open Policy Agent patterns) and pre-deployment validation checks
  • Hands-on: building a GitHub Actions workflow to plan and apply Terraform in a sandbox subscription

Module 8: Security, Secrets, and Operational Practices

  • Securing secrets: integrating Azure Key Vault and preventing sensitive data leakage into state files
  • Implementing access control, RBAC, and the principle of least privilege for automation accounts
  • Detecting drift, reconciling state, and establishing basic remediation workflows
  • Operational checklist: covering backup strategies, auditing, and governance for Terraform-managed infrastructure

Module 9: Testing, Debugging, and Troubleshooting

  • Techniques for debugging Terraform configurations and interpreting plan diffs effectively
  • Approaches to unit and integration testing (utilizing terraform validate, tflint, and kitchen-terraform)
  • Identifying common error patterns and developing resolution strategies
  • Lab: running validation and linting tools to identify and rectify configuration issues

Module 10: Capstone Project — Hybrid Deployment Scenario

  • Design exercise: planning a comprehensive on-prem plus Azure device deployment using previously learned patterns
  • Implementation of core components using modules, remote state, and CI/CD pipeline snippets
  • Presentation of the solution, discussion of architectural trade-offs, and review of operational runbooks
