c7g.medium

Analysis

The c7g.medium is a compute optimized instance in the c7g series with 1 vCPU and 2 GiB of memory on AWS Graviton3 (up to 2.5 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.

Running it in Mumbai instead of São Paulo saves $22.63 a month per instance: $0.0245/hour against $0.0555/hour, a 127% spread.

At $0.0363/hour on demand in US East (N. Virginia), about $26.50 a month, the c7g.medium is one of the cheaper ways to buy compute optimized capacity: only 6% of the 291 current compute optimized types cost less per vCPU-hour than its $0.0363.

It is the cheapest of the 4 processor variants AWS sells at this size and generation. The c7gn.medium on AWS Graviton3 costs 72% more, and the c7gd.medium and the c7a.medium also sit above it.

Compared with the previous generation, it costs 6.8% more than the c6g.medium on AWS Graviton2 ($1.68 more a month per instance), in exchange for the newer processor. The newer c8g.medium on AWS Graviton4 is 9.9% dearer at $0.0399/hour.

Looking beyond its own line, 2 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.
