Analysis

The r8g.medium is a memory optimized instance in the r8g series with 1 vCPU and 8 GiB of memory on AWS Graviton4 (up to 2.7 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.

Running it in Mumbai instead of São Paulo saves $38.29 a month per instance: $0.0413/hour against $0.0937/hour, a 127% spread.

It is the cheapest of the 5 processor variants AWS sells at this size and generation. The r8gn.medium on AWS Graviton4 costs 55% more, and the r8gd.medium, the r8a.medium and the r8gb.medium also sit above it.

At $0.0589/hour on demand in US East (N. Virginia), about $43.00 a month, the r8g.medium is one of the cheaper ways to buy memory optimized capacity: only 12% of the 385 current memory optimized types cost less per vCPU-hour than its $0.0589.

Compared with the previous generation, it costs 9.9% more than the r7g.medium on AWS Graviton3 ($3.88 more a month per instance), in exchange for the newer processor. The newer r9g.medium on AWS Graviton5 is 9.0% dearer at $0.0642/hour.

Looking beyond its own line, 3 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.
