Analysis
The r6gd.16xlarge is a memory optimized instance in the r6gd series with 64 vCPUs and 512 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 $2,515 a month per instance: $2.39/hour against $5.84/hour, a 144% spread.
The newer r7gd.16xlarge on AWS Graviton3 is 18% dearer at $4.35/hour.
Within the same generation and size, the r6g.16xlarge on AWS Graviton2 costs $3.23/hour, 12% less ($336 a month). The other variants are the r6a.16xlarge at $3.63, the r6i.16xlarge at $4.03 and the r6id.16xlarge at $4.84.
At $3.69/hour on demand in US East (N. Virginia), about $2,691 a month, the r6gd.16xlarge 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 (2 x 1900 GB NVMe SSD), which is fast but lost when the instance stops. Network: 25 Gigabit.
Looking beyond its own line, 4 of 39 current types with 64 vCPUs and similar memory are cheaper. The cheapest of those is the r7g.16xlarge on AWS Graviton3 at $3.43/hour.
Reserving it for a year with no upfront payment cuts the Linux rate to $2.32/hour, which beats on demand once it runs more than 63% of the time; three years brings it to $1.59/hour, 57% below on demand.
