Analysis
The i8g.12xlarge is a storage optimized instance in the i8g series with 48 vCPUs and 384 GiB of memory on AWS Graviton4 (up to 2.7 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 i8ge.12xlarge on AWS Graviton4 costs 38% more, and no others also sit above it.
Running it in N. Virginia instead of São Paulo saves $1,794 a month per instance: $4.12/hour against $6.58/hour, a 60% spread.
On demand it costs $4.12/hour in US East (N. Virginia), $3,006 a month if left running, which puts it mid-table for storage optimized types at the 28th percentile per vCPU ($0.0858 per vCPU-hour) and the 24th percentile per GiB ($0.0107 per GiB-hour).
Looking beyond its own line, 25 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 is size 6 of 9 in the i8g series. Stepping up to the i8g.16xlarge gives 64 vCPUs and 512 GiB for $1,002 more a month. Dropping to the i8g.8xlarge saves $1,002 a month.
Storage is EBS only. Network: Up to 28.125 Gigabit.
