Analysis
The r8g.24xlarge is a memory optimized instance in the r8g series with 96 vCPUs and 768 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 $3,676 a month per instance: $3.96/hour against $9.00/hour, a 127% spread.
It is the cheapest of the 5 processor variants AWS sells at this size and generation. The r8id.24xlarge on Intel Xeon Scalable (Granite Rapids) costs 41% more, and the r8i.24xlarge, the r8gd.24xlarge and the r8a.24xlarge also sit above it.
At $5.66/hour on demand in US East (N. Virginia), about $4,128 a month, the r8g.24xlarge 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.
The newer r9g.24xlarge on AWS Graviton5 is 9.0% dearer at $6.16/hour.
It is size 9 of 10 in the r8g series. Stepping up to the r8g.48xlarge gives 192 vCPUs and 1536 GiB for $4,128 more a month. Dropping to the r8g.16xlarge saves $1,376 a month.
Looking beyond its own line, 2 of 35 current types with 96 vCPUs and similar memory are cheaper. The cheapest of those is the r5a.24xlarge on AMD EPYC 7571 at $5.42/hour.
