In this module, we will dive into using expressions and functions to enhance your Terraform configurations. You'll learn how to work with operators, iterate over data structures with for expressions, and apply built-in functions to transform data. Additionally, we will explore splat expressions for efficient referencing of multiple resource attributes and demonstrate methods for converting between lists and maps.

In this module, we will cover managing multiple resources in Terraform using the count and for_each meta-arguments. You will practice creating EC2 instances dynamically using list and map variables, and learn how to extend configurations to handle subnet information for efficient resource placement. Additionally, we will explore validation techniques to maintain data integrity and consistency across your infrastructure.

In this section, we will guide you through a hands-on project to manage IAM users in AWS. You will learn how to define users, roles, and permissions, securely configure passwords, and implement AWS managed policies. By the end of the project, you’ll have practical experience in managing IAM users and roles and ensuring the security of your AWS environment.

In this module, we will focus on Terraform modules, helping you structure and reuse configurations more efficiently. You will explore public modules from the Terraform Registry, practice building custom modules, and learn how to test and publish them. Best practices for module design will also be covered to ensure that your code is both maintainable and reusable.

In this module, we will explore the use of preconditions, postconditions, and check blocks to validate and verify your Terraform resources. You will learn how to implement these features to ensure that your resources are deployed and configured correctly, reducing the chance of errors. By automating validation, you can maintain a consistent and reliable infrastructure.

In this module, we will explore how to manage Terraform's state file and perform operations like refactoring resources, importing existing infrastructure, and removing resources from the state. You will learn to manipulate the state file effectively and use commands like taint to ensure that resources are properly replaced or managed, all while maintaining the integrity of your infrastructure.
