Analysis
The i7i.12xlarge is a storage optimized instance in the i7i series with 48 vCPUs and 384 GiB of memory on Intel Xeon Scalable (Emerald Rapids) (up to 3.2 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
It is the cheapest of the 2 processor variants AWS sells at this size and generation. The i7ie.12xlarge on Intel Xeon Scalable (Emerald Rapids) costs 38% more, and no others also sit above it.
Running it in N. Virginia instead of São Paulo saves $1,972 a month per instance: $4.53/hour against $7.23/hour, a 60% spread.
Looking beyond its own line, 31 of 40 current types with 48 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.12xlarge on AWS Graviton2 at $2.42/hour.
It has local instance storage (3 x 3750 GB NVMe SSD), which is fast but lost when the instance stops. Network: Up to 28.125 Gigabit.
On demand it costs $4.53/hour in US East (N. Virginia), $3,307 a month if left running, which puts it mid-table for storage optimized types at the 47th percentile per vCPU ($0.0944 per vCPU-hour) and the 36th percentile per GiB ($0.0118 per GiB-hour).
It is size 6 of 9 in the i7i series. Stepping up to the i7i.16xlarge gives 64 vCPUs and 512 GiB for $1,102 more a month. Dropping to the i7i.8xlarge saves $1,102 a month.
