Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

• http://mvdirona.com/jrh/talksandpapers/jamesrh_lisa.pdf

Basic tenets

• Does the design expect failures to happen regularly and handle them gracefully?
• Have we kept things as simple as possible?

'''
The association between a snapshot and its corresponding AMI and device name is tedious to extract by hand. 

This script names all snapshots "<AMI name> (<AMI id>) <device name>", which makes the associations much easier 
to see. It also makes it easy to find "orphaned" snapshots, i.e. those that aren't associated with extant AMIs.
