Analysis
The r6idn.8xlarge is a memory optimized instance in the r6idn series with 32 vCPUs and 256 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.8xlarge on AWS Graviton2 costs $1.61/hour, 48% less ($1,105 a month), though switching means rebuilding software for arm64. The other variants are the r6a.8xlarge at $1.81, the r6gd.8xlarge at $1.84 and the r6i.8xlarge at $2.02.
Running it in N. Virginia instead of Sydney saves $506 a month per instance: $3.13/hour against $3.82/hour, a 22% spread. It is not offered in São Paulo, London and Mumbai, so plan around that if you need a presence there.
On demand it costs $3.13/hour in US East (N. Virginia), $2,282 a month if left running, which puts it mid-table for memory optimized types at the 72nd percentile per vCPU ($0.0977 per vCPU-hour) and the 88th percentile per GiB ($0.0122 per GiB-hour).
Looking beyond its own line, 34 of 41 current types with 32 vCPUs and similar memory are cheaper. The cheapest of those is the r7g.8xlarge on AWS Graviton3 at $1.71/hour.
It has local instance storage (1 x 1900 GB NVMe SSD), which is fast but lost when the instance stops. Network: 50000 Megabit.
