Managing AWS Infrastructure with Terraform

Part 1: Infrastructure as Code

In this section, we will introduce the benefits that Infrastructure as Code (IaC) can bring to organizations and how IaC fits within modern DevOps best practices.

• Motivation for Infrastructure as Code
• Applying Infrastructure as Code in DevOps
• Infrastructure as Code principles and best practices
• Benefits of Infrastructure as Code
• The case for Terraform

Part 2: Terraform Overview

This section provides an overview of Terraform concepts and vocabulary and instructs how Terraform manages infrastructure configuration in cloud environments.

• Terraform architecture
• Terraform configuration language overview
• Terraform CLI
• The lifecycle of a configuration
• Managing configuration state

Hands-on Labs:

• Using the Terraform CLI
• Setting up a Terraform project

Part 3: AWS Resources

In this section, participants will get hands-on practice using Terraform to create a simple application environment in AWS and learn the essential constructs in Terraform for defining resources.

• Resource types
• Best practices in declaring resources
• Network resources (VPC, subnet, security group)
• Compute resources (virtual machine)
• Storage resources (database)
• Local values in a configuration
• Augmenting a configuration with data sources

Hands-on Labs:

• Creating a VPC and subnets
• Adding a virtual machine into your VPC
• Adding a database to your VPC
• Using locals for replicated values
• Using a data source to read external configuration

Part 4: Terraform Programming

This section introduces programming constructs within Terraform that enable you to add more control and flexibility in defining resources.

• Data structures (primitives, maps, lists, objects, etc.)
• Types of expressions to set values
• Creating multiples of a resource
• Dynamic blocks
• Parameterizing a configuration with variables
• Outputs from a configuration
• Functions
• Handling errors

Hands-on Labs:

• Using variables in a configuration
• Getting outputs from a configuration
• Creating a re-sizable cluster of virtual machines
• Creating multiple resources through iteration loops
• Leveraging functions in your code

Part 5: Modules

This section shows how modules can be used to create reusable components in Terraform and teaches best practices in organizing Terraform code.

• Purpose of modules
• Module structure and code organization
• Invoking modules
• Module sources and versioning
• Nested modules
• Publishing modules

Hands-on Labs:

• Using an external module in your configuration
• Refactoring your code to implement a module

Part 6: Wrapping Up

This section wraps up the course with reviews to reinforce what you have learned.

• Reference material to learn more
• Course review
• Next steps
