Analysis
The c6g.12xlarge is a compute optimized instance in the c6g series with 48 vCPUs and 96 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 $1,090 a month per instance: $1.02/hour against $2.52/hour, a 146% spread.
Nothing else with 48 vCPUs and similar memory is cheaper: among 30 current same-shape types it has the lowest on-demand price.
At $1.63/hour on demand in US East (N. Virginia), about $1,191 a month, the c6g.12xlarge is one of the cheaper ways to buy compute optimized capacity: only 1% 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.12xlarge on AWS Graviton2 costs 27% more, and the c6a.12xlarge, the c6gd.12xlarge and the c6i.12xlarge also sit above it.
The newer c7g.12xlarge on AWS Graviton3 is 6.6% dearer at $1.74/hour.
It is size 7 of 8 in the c6g series. Stepping up to the c6g.16xlarge gives 64 vCPUs and 128 GiB for $397 more a month. Dropping to the c6g.8xlarge saves $397 a month.
