c7gn.large

Analysis

The c7gn.large is a compute optimized instance in the c7gn series with 2 vCPUs and 4 GiB of memory on AWS Graviton3 (up to 2.6 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.

Within the same generation and size, the c7g.large on AWS Graviton3 costs $0.0725/hour, 42% less ($38.18 a month). The other variants are the c7i-flex.large at $0.0848, the c7i.large at $0.0892 and the c7gd.large at $0.0907.

Compared with the previous generation, it costs 44% more than the c6gn.large on AWS Graviton2 ($28.03 more a month per instance), in exchange for the newer processor. The newer c8gn.large on AWS Graviton4 is 5.0% cheaper at $0.1185/hour, which makes the c7gn.large hard to justify for new deployments.

Running it in N. Virginia instead of Tokyo saves $23.80 a month per instance: $0.1248/hour against $0.1574/hour, a 26% spread. It is not offered in Canada Central, São Paulo, Frankfurt, Mumbai, Singapore and Sydney, so plan around that if you need a presence there.

Per vCPU it is one of the dearer compute optimized types: 87% of the 291 current types in the family cost less than its $0.0624 per vCPU-hour. The premium mostly pays for a newer processor or a specialised configuration. On demand it is $0.1248/hour in US East (N. Virginia), or $91.10 for a 730-hour month.
