c9gd.large

Analysis

The c9gd.large is a compute optimized instance in the c9gd series with 2 vCPUs and 4 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.large on AWS Graviton5 costs $0.0869/hour, 19% less ($14.50 a month).

Running it in N. Virginia instead of Tokyo saves $21.11 a month per instance: $0.1068/hour against $0.1357/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.large on AWS Graviton4 ($6.44 more a month per instance), in exchange for the newer processor.

On demand it costs $0.1068/hour in US East (N. Virginia), $77.96 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, 26 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.
