Analysis
The c6i.8xlarge is a compute optimized instance in the c6i series with 32 vCPUs and 64 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 c6g.8xlarge on AWS Graviton2 costs $1.09/hour, 20% less ($199 a month), though switching means rebuilding software for arm64. The other variants are the c6a.8xlarge at $1.22, the c6gd.8xlarge at $1.23 and the c6gn.8xlarge at $1.38.
At $1.36/hour on demand in US East (N. Virginia), about $993 a month, the c6i.8xlarge 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 $537 a month per instance: $1.36/hour against $2.10/hour, a 54% spread.
Reserving it for a year with no upfront payment cuts the Linux rate to $0.8996/hour, which beats on demand once it runs more than 66% of the time; three years brings it to $0.5988/hour, 56% below on demand. Windows Server roughly doubles the bill at $2.83/hour, because the licence is charged per vCPU.
The newer c7i.8xlarge on Intel Xeon Scalable (Sapphire Rapids) is 5.0% dearer at $1.43/hour.
