AWS is not optimized or built for people who want to reserve their own personal server for a year or more. Another cost option that the author didn't mention are spot instances. An r4.16xlarge spot instance in Paris for one year would cost $8,900, about half the price of OVH and that is assuming that the customer needs the server 24x7. Having a server 24x7 obviously wouldn't work on spot, but the point is that AWS is built more for customers who are frequently creating, destroying, and scaling their clusters based on need.
