r8in.96xlarge

Analysis

The r8in.96xlarge is a memory optimized instance in the r8in series with 384 vCPUs and 3072 GiB of memory on Intel Xeon Scalable (Granite Rapids) (up to 3.9 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.

Within the same generation and size, the r8i.96xlarge on Intel Xeon Scalable (Granite Rapids) costs $26.67/hour, 34% less ($9,850 a month). The other variants are the r8id.96xlarge at $31.93, the r8ib.96xlarge at $40.17 and the r8idn.96xlarge at $45.02.

Running it in N. Virginia instead of Tokyo saves $6,296 a month per instance: $40.17/hour against $48.79/hour, a 21% spread. It is not offered in Canada Central, São Paulo, London, Mumbai, Singapore and Sydney, so plan around that if you need a presence there.

Per vCPU it is one of the dearer memory optimized types: 82% of the 385 current types in the family cost less than its $0.1046 per vCPU-hour. The premium mostly pays for the extra memory per vCPU. On demand it is $40.17/hour in US East (N. Virginia), or $29,321 for a 730-hour month.

It is the largest of the 11 r8in sizes. Dropping to the r8in.48xlarge saves $14,661 a month.

Windows Server roughly adds 44% to the bill at $57.83/hour, because the licence is charged per vCPU.
