Analysis
The r5dn.xlarge is a memory optimized instance in the r5dn series with 4 vCPUs and 32 GiB of memory on Intel Xeon Platinum 8259 (Cascade Lake) (up to 3.1 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Within the same generation and size, the r5a.xlarge on AMD EPYC 7571 costs $0.2260/hour, 32% less ($78.84 a month). The other variants are the r5.xlarge at $0.2520, the r5ad.xlarge at $0.2620 and the r5d.xlarge at $0.2880.
Running it in N. Virginia instead of Sydney saves $54.02 a month per instance: $0.3340/hour against $0.4080/hour, a 22% spread. It is not offered in Canada Central, São Paulo, London and Mumbai, so plan around that if you need a presence there.
On demand it costs $0.3340/hour in US East (N. Virginia), $244 a month if left running, which puts it mid-table for memory optimized types at the 57th percentile per vCPU ($0.0835 per vCPU-hour) and the 73rd percentile per GiB ($0.0104 per GiB-hour).
It has local instance storage (1 x 150 GB NVMe SSD), which is fast but lost when the instance stops. Network: Up to 25 Gigabit.
Looking beyond its own line, 26 of 45 current types with 4 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.xlarge on AWS Graviton2 at $0.2016/hour.
