c9gd.medium

Analysis

The c9gd.medium is a compute optimized instance in the c9gd series with 1 vCPU and 2 GiB of memory on AWS Graviton5 (up to 3.3 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.

Within the same generation and size, the c9g.medium on AWS Graviton5 costs $0.0435/hour, 19% less ($7.25 a month).

Running it in N. Virginia instead of Tokyo saves $10.56 a month per instance: $0.0534/hour against $0.0679/hour, a 27% spread. It is not offered in Canada Central, São Paulo, Ireland, London, Mumbai and Sydney, so plan around that if you need a presence there.

Compared with the previous generation, it costs 9.0% more than the c8gd.medium on AWS Graviton4 ($3.22 more a month per instance), in exchange for the newer processor.

On demand it costs $0.0534/hour in US East (N. Virginia), $38.98 a month if left running, which puts it mid-table for compute optimized types at the 65th percentile per vCPU ($0.0534 per vCPU-hour) and the 69th percentile per GiB ($0.0267 per GiB-hour).

Looking beyond its own line, 10 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.
