Description

Terraform uses graph theory to plot relationships between resources. This mathematical process is used to determine the necessary steps to take for provisioning and destroying infrastructure. Understanding how to create resource dependencies within Terraform configurations is crucial for Terraform developers. It can prevent headaches in the future with timing issues and bugs in infrastructure deployments.

In this lab, you will learn how to create implicit dependencies between resources and experience firsthand what happens when Terraform resource dependencies are overlooked.
