14400 vCPU of R4 for 3yr reserved, monthly is $300k MRC. I'm guessing you'd run ceph or rook on your bare metal and have ~8 1TB SSD per server, so 75 servers * 8 SSDs /3 (for replication) is 200TB with decent performance by three data centers for 600TB usable compared to EC2 GP2 at $.10/GB comes to roughly $60k MRC.
Less any network charges that's $360k vs. $156k self-hosted. Guess I'm wrong. It's only twice as much.
