exercise 2

Terraform is an infrastructure-as-code (IaC) platform that allows users to manage and integrate various external resources as united infrastructure. This is achieved by using the proprietary HashiCorp Configuration Language (HCL) or JSON.

This course is a comprehensive introduction to Terraform. It helps users build confidence through foundational understanding of Terraform’s approach to resource management and the coding environment. You’ll start with an introduction to Terraform and learn how to set up local files. You’ll then take your learning to the cloud, managing remote resources by identifying unique resources and dependencies. Next, you’ll learn the modules and data structures unique to Terraform before practicing various techniques for infrastructure management, including triggers, resource creation, and backend code.

By the end of this course, you’ll have learned to think creatively and be ready to solve production and deployment problems through Terraform.

Beginner’s Guide to Terraform

# Explicit dependency
We created a resource that Terraform knew was dependent on another (the VPC subnet) in implicit dependencies. It was dependent because the logic within the `provider` code knows that.

But what about dependencies that are not part of the structure of resources themselves but part of the logic of our application?

For example, we might have a dependency in our application between an EC2 virtual machine on AWS and a load balancer on Azure. This would not be captured automatically by Terraform, but fortunately, we can specify it.


We’ll use this scenario to figure out what’s different this time. First, we need to create and initialize a new directory: `ltthw_dependencies`.


>**Note**:  For environment variables, we use `TF_VAR_region`, `TF_VAR_YOURSECRETKEY` and `TF_VAR_YOURACCESSKEY` in `dependencies.tf`.
