c8g.medium

Analysis

The c8g.medium is a compute optimized instance in the c8g series with 1 vCPU and 2 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 $24.89 a month per instance: $0.0270/hour against $0.0611/hour, a 126% spread.

It is the cheapest of the 5 processor variants AWS sells at this size and generation. The c8gn.medium on AWS Graviton4 costs 49% more, and the c8gd.medium, the c8a.medium and the c8gb.medium also sit above it.

At $0.0399/hour on demand in US East (N. Virginia), about $29.11 a month, the c8g.medium 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 9.9% more than the c7g.medium on AWS Graviton3 ($2.61 more a month per instance), in exchange for the newer processor. The newer c9g.medium on AWS Graviton5 is 9.0% dearer at $0.0435/hour.

Looking beyond its own line, 4 of 15 current types with 1 vCPU and similar memory are cheaper. The cheapest of those is the t2.small on Intel Xeon Family at $0.0230/hour. It is burstable, so it only suits workloads that do not run the CPU flat out.
