Ask HN: Good Amazon EC2 tutorials for beginners?

I'm new to Amazon EC2. Having setup an EC2 instance after following AWS' getting started guide, I'm looking for some simple tutorials to get an experience with the EC2 workflow and recommended frameworks to use in different scenarios.

Just to begin, I'm trying to code a program as follows: 1. Query few open datasets (eg. weather datasets) 2. Retrieve the data 3. Save the data on Parse.com to make it searchable
