Analysis
The r7a.medium is a memory optimized instance in the r7a series with 1 vCPU and 8 GiB of memory on AMD EPYC 9R14 (up to Up to 3.7 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Within the same generation and size, the r7g.medium on AWS Graviton3 costs $0.0536/hour, 30% less ($16.41 a month), though switching means rebuilding software for arm64. The other variants are the r7gd.medium at $0.0680.
Running it in N. Virginia instead of Frankfurt saves $11.45 a month per instance: $0.0761/hour against $0.0918/hour, a 21% spread. It is not offered in Canada Central, São Paulo, London, Mumbai, Singapore and Sydney, so plan around that if you need a presence there.
Looking beyond its own line, 7 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.
On demand it costs $0.0761/hour in US East (N. Virginia), $55.54 a month if left running, which puts it mid-table for memory optimized types at the 47th percentile per vCPU ($0.0761 per vCPU-hour) and the 63rd percentile per GiB ($0.00951 per GiB-hour).
The newer r8a.medium on AMD EPYC 9R45 is 5.0% dearer at $0.0799/hour.
