Analysis
The i4g.4xlarge is a storage optimized instance in the i4g series with 16 vCPUs and 128 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 $538 a month per instance: $1.24/hour against $1.97/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 $1.24/hour on demand in US East (N. Virginia), about $902 a month, the i4g.4xlarge 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.4xlarge on Intel Xeon 8375C (Ice Lake) costs 11% more, and no others also sit above it.
It has local instance storage (1 x 3750 GB SSD), which is fast but lost when the instance stops. Network: Up to 25 Gigabit.
Looking beyond its own line, 21 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.
