Hi Luqman,
Your target is still not clear to me. Please break it into sub
tasks so that we can help more efficiently. Or you can try Kepler first
before getting more specific questions to ask.
About Kepler workflow execution on EC2, I did some experiments on
it and don't think it is hard to execute Kepler workflows on EC2.
Best wishes
Sincerely yours
