Analysis
The c6i.xlarge is a compute optimized instance in the c6i series with 4 vCPUs and 8 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.xlarge on AWS Graviton2 costs $0.1360/hour, 20% less ($24.82 a month), though switching means rebuilding software for arm64. The other variants are the c6a.xlarge at $0.1530, the c6gd.xlarge at $0.1536 and the c6gn.xlarge at $0.1728.
At $0.1700/hour on demand in US East (N. Virginia), about $124 a month, the c6i.xlarge 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 $67.16 a month per instance: $0.1700/hour against $0.2620/hour, a 54% spread.
Reserving it for a year with no upfront payment cuts the Linux rate to $0.1125/hour, which beats on demand once it runs more than 66% of the time; three years brings it to $0.0748/hour, 56% below on demand. Windows Server roughly doubles the bill at $0.3540/hour, because the licence is charged per vCPU.
The newer c7i.xlarge on Intel Xeon Scalable (Sapphire Rapids) is 5.0% dearer at $0.1785/hour.
