Analysis
The r8gb.medium is a memory optimized instance in the r8gb series with 1 vCPU and 8 GiB of memory on AWS Graviton4 (up to 2.8 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Within the same generation and size, the r8g.medium on AWS Graviton4 costs $0.0589/hour, 35% less ($23.49 a month). The other variants are the r8gd.medium at $0.0735, the r8a.medium at $0.0799 and the r8gn.medium at $0.0911.
Its price is almost flat across the 2 regions that offer it ($0.0911 to $0.0911/hour), so latency and data residency should decide where it runs. It is not offered in Ohio, Canada Central, São Paulo, Ireland, London, Frankfurt, Mumbai, Singapore, Sydney and Tokyo, so plan around that if you need a presence there.
On demand it costs $0.0911/hour in US East (N. Virginia), $66.50 a month if left running, which puts it mid-table for memory optimized types at the 64th percentile per vCPU ($0.0911 per vCPU-hour) and the 80th percentile per GiB ($0.0114 per GiB-hour).
Looking beyond its own line, 10 of 13 current types with 1 vCPU and similar memory are cheaper. The cheapest of those is the r6g.medium on AWS Graviton2 at $0.0504/hour.
It is the smallest of the 10 r8gb sizes. Stepping up to the r8gb.large gives 2 vCPUs and 16 GiB for $66.50 more a month.
