This tutorial covers everything you need to know to start using Amazon Web Services (AWS). We will go through the step-by-step process of creating a free tier account, setting up security, and building your first EC2 instance. 

What I love about EC2 instances in AWS is the flexibility. If you accidentally mess something up to where it is unrecoverable, simply delete that instance and recreate it. You will be back up and running in minutes.

NOTE: Make sure that you stop any instances that you are not using. You WILL be charged for anything you use beyond the free-tier offering so be mindful of your consumption.
