Analysis
The r5d.4xlarge is a memory optimized instance in the r5d series with 16 vCPUs and 128 GiB of memory on Intel Xeon Platinum 8175 (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.4xlarge on AMD EPYC 7571 costs $0.9040/hour, 22% less ($181 a month). The other variants are the r5.4xlarge at $1.01, the r5ad.4xlarge at $1.05 and the r5n.4xlarge at $1.19.
Running it in N. Virginia instead of São Paulo saves $491 a month per instance: $1.15/hour against $1.82/hour, a 58% spread.
On demand it costs $1.15/hour in US East (N. Virginia), $841 a month if left running, which puts it mid-table for memory optimized types at the 34th percentile per vCPU ($0.0720 per vCPU-hour) and the 50th percentile per GiB ($0.00900 per GiB-hour).
It has local instance storage (2 x 300 GB NVMe SSD), which is fast but lost when the instance stops. Network: Up to 10 Gigabit.
Looking beyond its own line, 15 of 42 current types with 16 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.4xlarge on AWS Graviton2 at $0.8064/hour.
It is size 4 of 8 in the r5d series. Stepping up to the r5d.8xlarge gives 32 vCPUs and 256 GiB for $841 more a month. Dropping to the r5d.2xlarge saves $420 a month.
