> $802,538.64 for the 3-year term. I wonder how that compares to building your own on-premise host with that much RAM This was discussed a couple days ago in a different thread [1], when 4TB was the EC2 limit. $400k for the current-gen (224 cores) or, as a sibling comment [2] notes, $250k for the previous CPU generation (which can use twice as many DIMMs of half the density and only 192 cores of that). > obviously, there's operational costs to consider as well We can estimate an upper bound on this, given that the current-gen system has N+2 5x1600W 96% efficient PSUs, so 5kW max. If you're paying a colo $.50/kWh, that's another $66k over 3 years worst case. Realistically, though, CPUs with a max TDP of 1640W, DIMMs (generously) 700W, leaves plenty of room for fans, SSDs and other overhead before getting to 3kW or $40k, and that's still assuming running full-bore the whole time. There are obviously also ancillary costs to AWS, such as data transfer and EBS. If you're already running your own hardware, it sure does look more attractive to pay $400k now and $40k over 3 years than to pay AWS $800k All Up Front (now). If not, perhaps it's more attractive to hand-wave away that $360k as saving the "hassle" of hiring someone who knows how to run equipment in a datacenter.
