It&#x27;s important to keep this in mind:  For most companies, their infrastructure is the second largest expense after their employees.  For Netflix, the cost of both pales in comparison to the content licensing (which in 2016 they have said is 6 <i>billion</i>).  Cost isn&#x27;t a huge concern, agility is far more important.<p>That being said, the all in cost for Netflix on AWS is still cheaper than trying to run nine datacenters around the world, which is what they would have to do to replace their usage of AWS.
