The title should say 'Amazon Redshift'.
At first I thought its going to be about redshift vs f.lux:

Edit: Why the downvote?
redshift (and flux) exist since before 2010, whereas Amazon Redshift got introduced just in 2012.
I think it is reasonable to assume that someone who has never heard of Amazon Redshift would think of the open source project first (that exists in various distributions as packages), and not the Amazon service.
