Analysis
The i3.16xlarge is a storage optimized instance in the i3 series with 64 vCPUs and 488 GiB of memory on Intel Xeon E5-2686 v4 (Broadwell) (up to 2.3 GHz), which makes it memory-heavy at 7.62 GiB of memory per vCPU.
At $4.99/hour on demand in US East (N. Virginia), about $3,644 a month, the i3.16xlarge is one of the cheaper ways to buy storage optimized capacity: only 14% of the 90 current storage optimized types cost less per vCPU-hour than its $0.0780.
Running it in N. Virginia instead of São Paulo saves $2,172 a month per instance: $4.99/hour against $7.97/hour, a 60% spread.
It has local instance storage (8 x 1900 GB NVMe SSD), which is fast but lost when the instance stops. Network: 20 Gigabit.
Looking beyond its own line, 22 of 39 current types with 64 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.16xlarge on AWS Graviton2 at $3.23/hour.
Reserving it for a year with no upfront payment cuts the Linux rate to $3.43/hour, which beats on demand once it runs more than 69% of the time; three years brings it to $2.42/hour, 52% below on demand. Windows Server roughly adds 59% to the bill at $7.94/hour, because the licence is charged per vCPU.
