Analysis
The r6g.8xlarge is a memory optimized instance in the r6g series with 32 vCPUs and 256 GiB of memory on AWS Graviton2 (up to 2.5 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Running it in Mumbai instead of São Paulo saves $1,119 a month per instance: $1.04/hour against $2.57/hour, a 147% spread.
Nothing else with 32 vCPUs and similar memory is cheaper: among 41 current same-shape types it has the lowest on-demand price.
At $1.61/hour on demand in US East (N. Virginia), about $1,177 a month, the r6g.8xlarge is one of the cheaper ways to buy memory optimized capacity: only 1% of the 385 current memory optimized types cost less per vCPU-hour than its $0.0504.
It is the cheapest of the 5 processor variants AWS sells at this size and generation. The r6id.8xlarge on Intel Xeon 8375C (Ice Lake) costs 50% more, and the r6a.8xlarge, the r6gd.8xlarge and the r6i.8xlarge also sit above it.
The newer r7g.8xlarge on AWS Graviton3 is 6.2% dearer at $1.71/hour.
It is size 6 of 8 in the r6g series. Stepping up to the r6g.12xlarge gives 48 vCPUs and 384 GiB for $589 more a month. Dropping to the r6g.4xlarge saves $589 a month.
