Simplest way to launch Drupal on AWS

What would be a best way to launch a simple Drupal web site on AWS? I've just started learning AWS. So far, from what I have learned, I can go either of the following ways. 1. Create an EC2 instance, install xampp and drupal, and keep developing web pages and web apps in EC2. I've done this, but I have not figured out how to make the web site accessible. (Do I need to setup elastic IP?) 2. Install Drupal on a local machine and develop all web pages and apps locally. And then upload all local files to S3. Then, is S3 enough to host a web site? EC2 instance is not needed? Also, who would I manage the upload for constant updates on Drupal modules and Drupal DB? Well, I need to dig more into EC2 and S3, but your input would be highly appreciated.
