u7in-24tb.224xlarge

Analysis

The u7in-24tb.224xlarge is a memory optimized instance in the u7in-24tb series with 896 vCPUs and 24576 GiB of memory on Intel Xeon Scalable (Sapphire Rapids) (up to 2.9 GHz), which makes it very memory-heavy at 27.43 GiB of memory per vCPU.

Within the same generation and size, the u7i-12tb.224xlarge on Intel Xeon Scalable (Sapphire Rapids) costs $126/hour, 54% less ($105,959 a month). The other variants are the u7in-16tb.224xlarge at $180 and the u7in-32tb.224xlarge at $361.

Running it in N. Virginia instead of São Paulo saves $117,639 a month per instance: $271/hour against $432/hour, a 60% spread. It is not offered in Canada Central, London, Mumbai, Singapore, Sydney and Tokyo, so plan around that if you need a presence there.

Per vCPU it is one of the dearer memory optimized types: 100% of the 385 current types in the family cost less than its $0.3022 per vCPU-hour. The premium mostly pays for the very fast networking. On demand it is $271/hour in US East (N. Virginia), or $197,634 for a 730-hour month.

Reserving it for a year with no upfront payment cuts the Linux rate to $167/hour, which beats on demand once it runs more than 62% of the time; three years brings it to $86.99/hour, 68% below on demand. Windows Server roughly adds 15% to the bill at $312/hour, because the licence is charged per vCPU.
