> A dedicated m4.16xLarge EC2 instance in AWS is $3987/month. You could build that same server for $15,000 through Dell, lease it at $400/month (OpEx)
Cherry-picking a bit there. You're entering a 3-year commitment with the Dell lease, but not with the EC2 lease. Take a 3-year RI on that EC2 instance, and the price drops considerably. If you also take away the 'dedicated' requirement, the 3-year RI is about twice as expensive, not ten times.
Edit: correction from Johnny555 above: this top-tier server doesn't have a 'dedicated' option, so there's not an 'extra' cost for that. It's just twice the price, if you do a 3-year commitment (as you are doing for the dell)
