r6id.large

Analysis

The r6id.large is a memory optimized instance in the r6id series with 2 vCPUs and 16 GiB of memory on Intel Xeon 8375C (Ice Lake) (up to 3.5 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.

Within the same generation and size, the r6g.large on AWS Graviton2 costs $0.1008/hour, 33% less ($36.79 a month), though switching means rebuilding software for arm64. The other variants are the r6a.large at $0.1134, the r6gd.large at $0.1152 and the r6i.large at $0.1260.

Running it in N. Virginia instead of Singapore saves $23.00 a month per instance: $0.1512/hour against $0.1827/hour, a 21% spread. It is not offered in Canada Central and São Paulo, so plan around that if you need a presence there.

On demand it costs $0.1512/hour in US East (N. Virginia), $110 a month if left running, which puts it mid-table for memory optimized types at the 43rd percentile per vCPU ($0.0756 per vCPU-hour) and the 59th percentile per GiB ($0.00945 per GiB-hour).

It has local instance storage (1 x 118 GB NVMe SSD), which is fast but lost when the instance stops. Network: Up to 12500 Megabit.

Looking beyond its own line, 19 of 44 current types with 2 vCPUs and similar memory are cheaper. The cheapest of those is the r7g.large on AWS Graviton3 at $0.1071/hour.
