Analysis
The c6i.32xlarge is a compute optimized instance in the c6i series with 128 vCPUs and 256 GiB of memory on Intel Xeon 8375C (Ice Lake) (up to 3.5 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.
Within the same generation and size, the c6a.32xlarge on AMD EPYC 7R13 costs $4.90/hour, 10% less ($397 a month). The other variants are the c6id.32xlarge at $6.45 and the c6in.32xlarge at $7.26.
At $5.44/hour on demand in US East (N. Virginia), about $3,971 a month, the c6i.32xlarge is one of the cheaper ways to buy compute optimized capacity: only 24% of the 291 current compute optimized types cost less per vCPU-hour than its $0.0425.
Running it in Mumbai instead of São Paulo saves $2,149 a month per instance: $5.44/hour against $8.38/hour, a 54% spread.
Reserving it for a year with no upfront payment cuts the Linux rate to $3.60/hour, which beats on demand once it runs more than 66% of the time; three years brings it to $2.40/hour, 56% below on demand. Windows Server roughly doubles the bill at $11.33/hour, because the licence is charged per vCPU.
It is the largest of the 9 c6i sizes. Dropping to the c6i.24xlarge saves $993 a month.
