Analysis
The im4gn.8xlarge is a storage optimized instance in the im4gn series with 32 vCPUs and 128 GiB of memory on AWS Graviton2 (up to 2.5 GHz), which makes it balanced at 4 GiB of memory per vCPU.
Running it in N. Virginia instead of Sydney saves $422 a month per instance: $2.91/hour against $3.49/hour, a 20% spread. It is not offered in São Paulo, so plan around that if you need a presence there.
Looking beyond its own line, 32 of 37 current types with 32 vCPUs and similar memory are cheaper. The cheapest of those is the m6g.8xlarge on AWS Graviton2 at $1.23/hour.
On demand it costs $2.91/hour in US East (N. Virginia), $2,125 a month if left running, which puts it mid-table for storage optimized types at the 42nd percentile per vCPU ($0.0909 per vCPU-hour) and the 84th percentile per GiB ($0.0227 per GiB-hour).
It has local instance storage (2 x 7500 GB SSD), which is fast but lost when the instance stops. Network: 50 Gigabit.
It is size 5 of 6 in the im4gn series. Stepping up to the im4gn.16xlarge gives 64 vCPUs and 256 GiB for $2,125 more a month. Dropping to the im4gn.4xlarge saves $1,062 a month.
