Analysis
The i8g.4xlarge is a storage optimized instance in the i8g series with 16 vCPUs and 128 GiB of memory on AWS Graviton4 (up to 2.7 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Running it in N. Virginia instead of São Paulo saves $598 a month per instance: $1.37/hour against $2.19/hour, a 60% spread.
On demand it costs $1.37/hour in US East (N. Virginia), $1,002 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, 27 of 42 current types with 16 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.4xlarge on AWS Graviton2 at $0.8064/hour.
It is size 4 of 9 in the i8g series. Stepping up to the i8g.8xlarge gives 32 vCPUs and 256 GiB for $1,002 more a month. Dropping to the i8g.2xlarge saves $501 a month.
Storage is EBS only. Network: Up to 25 Gigabit.
