spottpreis - Discover spot prices for AWS EC2 Instance

Description

This is a small helper for discovering the cheapest instance type in a region and within availability zones. It can be used to automate bidding on spot instances, returning the last bid for your selection.

What's with the name?

It's a German idiom describing a price that's either knocked down or ridiculously low, "spott" meaning ridicule or mockery and price obviously translates into price.
