Analysis
The im4gn.16xlarge is a storage optimized instance in the im4gn series with 64 vCPUs and 256 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 $844 a month per instance: $5.82/hour against $6.98/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 35 current types with 64 vCPUs and similar memory are cheaper. The cheapest of those is the m6g.16xlarge on AWS Graviton2 at $2.46/hour.
On demand it costs $5.82/hour in US East (N. Virginia), $4,249 a month if left running, which puts it mid-table for storage optimized types at the 41st percentile per vCPU ($0.0909 per vCPU-hour) and the 83rd percentile per GiB ($0.0227 per GiB-hour).
It has local instance storage (4 x 7500 GB SSD), which is fast but lost when the instance stops. Network: 100 Gigabit.
It is the largest of the 6 im4gn sizes. Dropping to the im4gn.8xlarge saves $2,125 a month.
Reserving it for a year with no upfront payment cuts the Linux rate to $3.73/hour, which beats on demand once it runs more than 64% of the time; three years brings it to $2.66/hour, 54% below on demand.
