u7in-16tb.224xlarge

Analysis

The u7in-16tb.224xlarge is a memory optimized instance in the u7in-16tb series with 896 vCPUs and 16384 GiB of memory on Intel Xeon Scalable (Sapphire Rapids) (up to 2.9 GHz), which makes it very memory-heavy at 18.29 GiB of memory per vCPU.

Within the same generation and size, the u7i-12tb.224xlarge on Intel Xeon Scalable (Sapphire Rapids) costs $126/hour, 30% less ($40,072 a month). The other variants are the u7in-24tb.224xlarge at $271 and the u7in-32tb.224xlarge at $361.

Running it in N. Virginia instead of São Paulo saves $78,421 a month per instance: $180/hour against $288/hour, a 60% spread. It is not offered in Canada Central and Tokyo, so plan around that if you need a presence there.

Per vCPU it is one of the dearer memory optimized types: 93% of the 385 current types in the family cost less than its $0.2014 per vCPU-hour. The premium mostly pays for the very fast networking. On demand it is $180/hour in US East (N. Virginia), or $131,747 for a 730-hour month.

Reserving it for a year with no upfront payment cuts the Linux rate to $111/hour, which beats on demand once it runs more than 62% of the time; three years brings it to $57.99/hour, 68% below on demand. Windows Server roughly adds 23% to the bill at $222/hour, because the licence is charged per vCPU.
