Analysis
The c5n.4xlarge is a compute optimized instance in the c5n series with 16 vCPUs and 42 GiB of memory on Intel Xeon Platinum 8124M (up to 3 GHz), which makes it balanced at 2.62 GiB of memory per vCPU.
Within the same generation and size, the c5a.4xlarge on AMD EPYC 7R32 costs $0.6160/hour, 29% less ($181 a month). The other variants are the c5.4xlarge at $0.6800, the c5ad.4xlarge at $0.6880 and the c5d.4xlarge at $0.7680.
Running it in Mumbai instead of São Paulo saves $339 a month per instance: $0.8640/hour against $1.33/hour, a 54% spread.
On demand it costs $0.8640/hour in US East (N. Virginia), $631 a month if left running, which puts it mid-table for compute optimized types at the 71st percentile per vCPU ($0.0540 per vCPU-hour) and the 22nd percentile per GiB ($0.0206 per GiB-hour).
Looking beyond its own line, 22 of 31 current types with 16 vCPUs and similar memory are cheaper. The cheapest of those is the c6g.4xlarge on AWS Graviton2 at $0.5440/hour.
Reserving it for a year with no upfront payment cuts the Linux rate to $0.5440/hour, which beats on demand once it runs more than 63% of the time; three years brings it to $0.3140/hour, 64% below on demand. Windows Server roughly adds 85% to the bill at $1.60/hour, because the licence is charged per vCPU.
