A/B Testing on Netflix

Everyone agrees that A/B (or more variants) testing makes sense and helps to automate decisions otherwise done by (naturally biased) humans, but I know embarrassingly few companies who have actually implemented this in theor day-to-day operations. While A/B testing sounds pretty easy, it's often complicated to set up and run it in a meaningful way. Always interesting to see how others do it, this post from Netflix's tech blog offers an in depth view on how they do it.
