Analysis
The c8i-flex.large is a compute optimized instance in the c8i-flex series with 2 vCPUs and 4 GiB of memory on Intel Xeon Scalable (Granite Rapids) (up to 3.9 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.
Within the same generation and size, the c8g.large on AWS Graviton4 costs $0.0798/hour, 10% less ($6.76 a month), though switching means rebuilding software for arm64. The other variants are the c8i.large at $0.0937, the c8gd.large at $0.0980 and the c8a.large at $0.1078.
Running it in Mumbai instead of São Paulo saves $35.18 a month per instance: $0.0890/hour against $0.1372/hour, a 54% spread.
On demand it costs $0.0890/hour in US East (N. Virginia), $64.98 a month if left running, which puts it mid-table for compute optimized types at the 38th percentile per vCPU ($0.0445 per vCPU-hour) and the 41st percentile per GiB ($0.0223 per GiB-hour).
Windows Server roughly doubles the bill at $0.1764/hour, because the licence is charged per vCPU.
Looking beyond its own line, 17 of 36 current types with 2 vCPUs and similar memory are cheaper. The cheapest of those is the t4g.medium on AWS Graviton2 at $0.0336/hour. It is burstable, so it only suits workloads that do not run the CPU flat out.
