Description

Variables are a critical component of developing Terraform code. They allow configurations to become dynamic and reusable by enabling them to take input values during deployment. By incorporating variables into your Terraform code, the same code used to deploy an EC2 into an environment can be used to deploy into another. This strategy can improve the speed and efficiency of teams. For example, a database server takes a DB expert to install the server and configure the database to the most optimal settings. With Terraform, a database server build can be defined in code and use variables to configure the server's unique values for each environment. Other team members can then use the code to deploy the same configuration without the database expertise. 

In this lab, you will learn how to create reusable Terraform configurations using variables.
