Honestly this is a terrible article, the only real point on display is "if you use AWS for EC2 reserved instances only, then you are overpaying". If your application can be interrupted, spun down, and spun up then congratulations you can use spot instances[1] at a fraction of the price (depending on your region and instance size). r4.16xlarge isn't available in France, so I'll use us-east-1 Reserved: $36,365 Spot: $9,665 UVH (Still France): $25,771 So if your system can tolerate nodes going up and down every once in a while (and some other caveats), it seems pretty dumb to pay for the dedicated server.
