c8in.large

Analysis

The c8in.large is a compute optimized instance in the c8in series with 2 vCPUs and 4 GiB of memory on Intel Xeon Scalable (Granite Rapids) (up to 3.9 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.

Within the same generation and size, the c8g.large on AWS Graviton4 costs $0.0798/hour, 41% less ($41.11 a month), though switching means rebuilding software for arm64. The other variants are the c8i-flex.large at $0.0890, the c8i.large at $0.0937 and the c8gd.large at $0.0980.

Running it in N. Virginia instead of Sydney saves $30.35 a month per instance: $0.1361/hour against $0.1777/hour, a 31% spread. It is not offered in Canada Central, São Paulo, London and Mumbai, so plan around that if you need a presence there.

Per vCPU it is one of the dearer compute optimized types: 92% of the 291 current types in the family cost less than its $0.0680 per vCPU-hour. The premium mostly pays for a newer processor or a specialised configuration. On demand it is $0.1361/hour in US East (N. Virginia), or $99.34 for a 730-hour month.

Looking beyond its own line, 33 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.
