Analysis
The r6gd.12xlarge is a memory optimized instance in the r6gd series with 48 vCPUs and 384 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 $1,886 a month per instance: $1.79/hour against $4.38/hour, a 144% spread.
Within the same generation and size, the r6g.12xlarge on AWS Graviton2 costs $2.42/hour, 12% less ($252 a month). The other variants are the r6a.12xlarge at $2.72, the r6i.12xlarge at $3.02 and the r6id.12xlarge at $3.63.
The newer r7gd.12xlarge on AWS Graviton3 is 18% dearer at $3.27/hour.
At $2.76/hour on demand in US East (N. Virginia), about $2,018 a month, the r6gd.12xlarge is one of the cheaper ways to buy memory optimized capacity: only 11% of the 385 current memory optimized types cost less per vCPU-hour than its $0.0576.
It has local instance storage (2 x 1425 GB NVMe SSD), which is fast but lost when the instance stops. Network: 20 Gigabit.
Reserving it for a year with no upfront payment cuts the Linux rate to $1.74/hour, which beats on demand once it runs more than 63% of the time; three years brings it to $1.19/hour, 57% below on demand.
