Analysis
The r6a.48xlarge is a memory optimized instance in the r6a series with 192 vCPUs and 1536 GiB of memory on AMD EPYC 7R13 (up to 3.6 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
The newer r7a.48xlarge on AMD EPYC 9R14 is 34% dearer at $14.61/hour.
Running it in Mumbai instead of Frankfurt saves $4,576 a month per instance: $6.86/hour against $13.13/hour, a 91% spread. It is not offered in São Paulo, so plan around that if you need a presence there.
Nothing else with 192 vCPUs and similar memory is cheaper: among 20 current same-shape types it has the lowest on-demand price.
At $10.89/hour on demand in US East (N. Virginia), about $7,947 a month, the r6a.48xlarge is one of the cheaper ways to buy memory optimized capacity: only 8% of the 385 current memory optimized types cost less per vCPU-hour than its $0.0567.
It is the largest of the 10 r6a sizes. Dropping to the r6a.32xlarge saves $2,649 a month.
Reserving it for a year with no upfront payment cuts the Linux rate to $7.20/hour, which beats on demand once it runs more than 66% of the time; three years brings it to $4.94/hour, 55% below on demand. Windows Server roughly adds 81% to the bill at $19.72/hour, because the licence is charged per vCPU.
