The 7PHP.com site has a tutorial they've recently posted showing you how to get Magnto 2 installed on an AWS instance running LEMP (Linux, Nginx, MySQL and PHP).

This article tries to demonstrate how to setup an AWS (EC2) instance, installing a LEMP stack, preparing the server environment to meet Magento’s requirements and then to finally install Magento v2 using command line approach. [...] I’m presenting in this article something which might otherwise seem to be a daunting approach – but I also see it as an approach which you can later automate by using Docker/Dockerfile for example or even using a Vagrant appliance.

He takes you through the entire process, including the setup of the account and instance on the AWS side, with screenshots along the way:
