Analysis
The c6g.16xlarge is a compute optimized instance in the c6g series with 64 vCPUs and 128 GiB of memory on AWS Graviton2 (up to 2.5 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.
Running it in Mumbai instead of São Paulo saves $1,453 a month per instance: $1.36/hour against $3.35/hour, a 146% spread.
At $2.18/hour on demand in US East (N. Virginia), about $1,588 a month, the c6g.16xlarge is one of the cheaper ways to buy compute optimized capacity: only 2% of the 291 current compute optimized types cost less per vCPU-hour than its $0.0340.
It is the cheapest of the 5 processor variants AWS sells at this size and generation. The c6gn.16xlarge on AWS Graviton2 costs 27% more, and the c6a.16xlarge, the c6gd.16xlarge and the c6i.16xlarge also sit above it.
The newer c7g.16xlarge on AWS Graviton3 is 6.6% dearer at $2.32/hour.
It is the largest of the 8 c6g sizes. Dropping to the c6g.12xlarge saves $397 a month.
Reserving it for a year with no upfront payment cuts the Linux rate to $1.37/hour, which beats on demand once it runs more than 63% of the time; three years brings it to $0.9400/hour, 57% below on demand.
