This is a beginner’s guide to creating your first Amazon AWS EC2 Linux Instance in one of the world’s largest hyper scalers.

Before Getting Started

If you are just starting out with Amazon AWS, I would encourage you to have a read of the following posts, which will help you set up your free-tier account, enable multi-factor authentication and set up a billing alarm

Video Tutorial Contents

Within this video tutorial, I walk you through step-by-step, in how to create an AWS EC2 Linux instance, where I give a full description of each setting being used.

Not only will we be setting up a Linux server, but I’ll be using some code that you can paste into the setup wizard which will automate the setup of the webserver. When we browse to the webserver, a static page will display the internal IP address, the public IP address, and the public DNS name. We can do this by making use of the internal metadata URL’s (which are explained within the video)

We will work through the tutorial together and go from this:

AWS EC2 User-Data Script

The user-data script referenced in the video is not too long but not too short either, therefore I’ve added the code to my GitHub page where you can easily copy it.

3rd Party Software Needed

In order to extract the private key from the public key pair, as explained in the video, you will need to download Putty and PuttyGen.
