I am using AWS and the EC2 instances extensively. However I had one issue with finding the best prices for on demand and spot instances. So I developed my own code to check the best prices.
The software will collect the data from AWS and will put it in a sqlite database. It keeps the data for 1 week. Any data older than 1 week will be replaces.
Here is a sample screenshot for graphical user interface
Here is an example of text output:
$ python awsEC2pricing.py -t 8 32
