Analysis
The r6gd.4xlarge is a memory optimized instance in the r6gd series with 16 vCPUs and 128 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 $629 a month per instance: $0.5979/hour against $1.46/hour, a 144% spread.
Within the same generation and size, the r6g.4xlarge on AWS Graviton2 costs $0.8064/hour, 12% less ($84.10 a month). The other variants are the r6a.4xlarge at $0.9072, the r6i.4xlarge at $1.01 and the r6id.4xlarge at $1.21.
The newer r7gd.4xlarge on AWS Graviton3 is 18% dearer at $1.09/hour.
At $0.9216/hour on demand in US East (N. Virginia), about $673 a month, the r6gd.4xlarge is one of the cheaper ways to buy memory optimized capacity: only 10% of the 385 current memory optimized types cost less per vCPU-hour than its $0.0576.
It has local instance storage (1 x 950 GB NVMe SSD), which is fast but lost when the instance stops. Network: Up to 10 Gigabit.
Reserving it for a year with no upfront payment cuts the Linux rate to $0.5806/hour, which beats on demand once it runs more than 63% of the time; three years brings it to $0.3981/hour, 57% below on demand.
