After configuration settings are complete, click "Review and Launch" and "Launch". If you are launching an AWS instance for the first time, you will need to generate a key pair.

Choose the "Create a new key pair" option from the drop down menu. Under key pair name, type "amazon" and click "save". The default location for saving files on a Mac is the "Downloads" folder -- that's where your key pair can be found. Next time you launch an instance, you can reuse the key pair you just generated.

If you have a previously generated key pair, you can reuse it to launch an instance. For this tutorial, we are calling the key pair "amazon.pem".
