u7i-12tb.224xlarge

Analysis

The u7i-12tb.224xlarge is a memory optimized instance in the u7i-12tb series with 896 vCPUs and 12288 GiB of memory on Intel Xeon Scalable (Sapphire Rapids) (up to 2.9 GHz), which makes it very memory-heavy at 13.71 GiB of memory per vCPU.

Running it in N. Virginia instead of São Paulo saves $54,568 a month per instance: $126/hour against $200/hour, a 60% spread. It is not offered in Canada Central, London and Tokyo, so plan around that if you need a presence there.

Per vCPU it is one of the dearer memory optimized types: 92% of the 385 current types in the family cost less than its $0.1402 per vCPU-hour. The premium mostly pays for the very fast networking. On demand it is $126/hour in US East (N. Virginia), or $91,675 for a 730-hour month.

It is the cheapest of the 4 processor variants AWS sells at this size and generation. The u7in-32tb.224xlarge on Intel Xeon Scalable (Sapphire Rapids) costs 187% more, and the u7in-16tb.224xlarge and the u7in-24tb.224xlarge also sit above it.

Reserving it for a year with no upfront payment cuts the Linux rate to $77.40/hour, which beats on demand once it runs more than 62% of the time; three years brings it to $40.42/hour, 68% below on demand. Windows Server roughly adds 33% to the bill at $167/hour, because the licence is charged per vCPU.
