Analysis
The i3en.12xlarge is a storage optimized instance in the i3en series with 48 vCPUs and 384 GiB of memory on Intel Xeon Platinum 8175 (up to 3.1 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Running it in N. Virginia instead of São Paulo saves $2,348 a month per instance: $5.42/hour against $8.64/hour, a 59% spread.
Looking beyond its own line, 35 of 40 current types with 48 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.12xlarge on AWS Graviton2 at $2.42/hour.
On demand it costs $5.42/hour in US East (N. Virginia), $3,960 a month if left running, which puts it mid-table for storage optimized types at the 58th percentile per vCPU ($0.1130 per vCPU-hour) and the 47th percentile per GiB ($0.0141 per GiB-hour).
It has local instance storage (4 x 7500 GB NVMe SSD), which is fast but lost when the instance stops. Network: 50 Gigabit.
Reserving it for a year with no upfront payment cuts the Linux rate to $3.69/hour, which beats on demand once it runs more than 68% of the time; three years brings it to $2.36/hour, 56% below on demand. Windows Server roughly adds 41% to the bill at $7.63/hour, because the licence is charged per vCPU.
