c8id.large

Analysis

The c8id.large is a compute optimized instance in the c8id 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, 28% less ($22.72 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 $25.29 a month per instance: $0.1109/hour against $0.1455/hour, a 31% spread. It is not offered in São Paulo, Ireland, London and Singapore, so plan around that if you need a presence there.

Per vCPU it is one of the dearer compute optimized types: 75% of the 291 current types in the family cost less than its $0.0554 per vCPU-hour. The premium mostly pays for the local NVMe disk. On demand it is $0.1109/hour in US East (N. Virginia), or $80.94 for a 730-hour month.

Looking beyond its own line, 28 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.
