Reusable EC2 Instances Using Terraform Modules

A guide to mastering EC2 restructuring

In this project, we will go through a simple restructuring of an EC2 Instance template forked from GitHub. We will recreate the code using modules to make it more reusable and adaptable to a development or production environment. We will also go through how to remotely store our Terraform state file in Terraform Cloud to ensure the state data can be shared between all members of a team.

I will be using Visual Studio Code as my IDE, but feel free to use Cloud9 or another IDE of your choice. The steps in this tutorial will differ slightly if you choose to use a different IDE.

Prerequisites
