Analysis
The i4g.8xlarge is a storage optimized instance in the i4g series with 32 vCPUs and 256 GiB of memory on AWS Graviton2 (up to 2.5 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Running it in N. Virginia instead of São Paulo saves $1,076 a month per instance: $2.47/hour against $3.95/hour, a 60% spread. It is not offered in London, Frankfurt, Mumbai and Tokyo, so plan around that if you need a presence there.
At $2.47/hour on demand in US East (N. Virginia), about $1,804 a month, the i4g.8xlarge is one of the cheaper ways to buy storage optimized capacity: only 8% of the 90 current storage optimized types cost less per vCPU-hour than its $0.0772.
It is the cheapest of the 2 processor variants AWS sells at this size and generation. The i4i.8xlarge on Intel Xeon 8375C (Ice Lake) costs 11% more, and no others also sit above it.
It has local instance storage (2 x 3750 GB SSD), which is fast but lost when the instance stops. Network: 18750 Megabit.
Looking beyond its own line, 21 of 41 current types with 32 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.8xlarge on AWS Graviton2 at $1.61/hour.
