r6id.2xlarge

Analysis

The r6id.2xlarge is a memory optimized instance in the r6id series with 8 vCPUs and 64 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.2xlarge on AWS Graviton2 costs $0.4032/hour, 33% less ($147 a month), though switching means rebuilding software for arm64. The other variants are the r6a.2xlarge at $0.4536, the r6gd.2xlarge at $0.4608 and the r6i.2xlarge at $0.5040.

Running it in N. Virginia instead of Singapore saves $91.98 a month per instance: $0.6048/hour against $0.7308/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 $0.6048/hour in US East (N. Virginia), $442 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 474 GB NVMe SSD), which is fast but lost when the instance stops. Network: Up to 12500 Megabit.

Looking beyond its own line, 19 of 45 current types with 8 vCPUs and similar memory are cheaper. The cheapest of those is the r7g.2xlarge on AWS Graviton3 at $0.4284/hour.
