c8g.large

Analysis

The c8g.large is a compute optimized instance in the c8g series with 2 vCPUs and 4 GiB of memory on AWS Graviton4 (up to 2.7 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.

Running it in Mumbai instead of São Paulo saves $49.79 a month per instance: $0.0540/hour against $0.1222/hour, a 126% spread.

It is the cheapest of the 5 processor variants AWS sells at this size and generation. The c8a.large on AMD EPYC 9R45 costs 35% more, and the c8i-flex.large, the c8i.large and the c8gd.large also sit above it.

At $0.0798/hour on demand in US East (N. Virginia), about $58.22 a month, the c8g.large is one of the cheaper ways to buy compute optimized capacity: only 17% of the 291 current compute optimized types cost less per vCPU-hour than its $0.0399.

Compared with the previous generation, it costs 10% more than the c7g.large on AWS Graviton3 ($5.30 more a month per instance), in exchange for the newer processor. The newer c9g.large on AWS Graviton5 is 9.0% dearer at $0.0869/hour.

Looking beyond its own line, 10 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.
