I would like to create a new instance based on my stored AMI.

I achieve this by the following code:

Answer 1

Depending on what you are trying to do (and how many servers you plan on starting), instead of polling for the instance start events, you could install on the AMI a simple program/script that runs once when the instance starts and sends out a notification to that effect, i.e. to an AWS SNS Topic.

The process that needs to know about new servers starting could then subscribe to this SNS topic, and would receive a push notifications each time a server starts.

Solves the same problem from a different angle; your mileage may vary.
