Analysis
The c7i-flex.xlarge is a compute optimized instance in the c7i-flex series with 4 vCPUs and 8 GiB of memory on Intel Xeon Scalable (Sapphire Rapids) (up to 3.2 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.
Within the same generation and size, the c7g.xlarge on AWS Graviton3 costs $0.1450/hour, 14% less ($17.94 a month), though switching means rebuilding software for arm64. The other variants are the c7i.xlarge at $0.1785, the c7gd.xlarge at $0.1814 and the c7a.xlarge at $0.2053.
At $0.1696/hour on demand in US East (N. Virginia), about $124 a month, the c7i-flex.xlarge is one of the cheaper ways to buy compute optimized capacity: only 21% of the 291 current compute optimized types cost less per vCPU-hour than its $0.0424.
Running it in Mumbai instead of São Paulo saves $66.99 a month per instance: $0.1696/hour against $0.2614/hour, a 54% spread.
Reserving it for a year with no upfront payment cuts the Linux rate to $0.1122/hour, which beats on demand once it runs more than 66% of the time; three years brings it to $0.0746/hour, 56% below on demand. Windows Server roughly doubles the bill at $0.3444/hour, because the licence is charged per vCPU.
The newer c8i-flex.xlarge on Intel Xeon Scalable (Granite Rapids) is 5.0% dearer at $0.1780/hour.
