Analysis
The r6a.32xlarge is a memory optimized instance in the r6a series with 128 vCPUs and 1024 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.32xlarge on AMD EPYC 9R14 is 34% dearer at $9.74/hour.
Running it in Mumbai instead of Frankfurt saves $3,051 a month per instance: $4.58/hour against $8.76/hour, a 91% spread. It is not offered in São Paulo, so plan around that if you need a presence there.
Nothing else with 128 vCPUs and similar memory is cheaper: among 14 current same-shape types it has the lowest on-demand price.
At $7.26/hour on demand in US East (N. Virginia), about $5,298 a month, the r6a.32xlarge 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 cheapest of the 5 processor variants AWS sells at this size and generation. The r6idn.32xlarge on Intel Xeon 8375C (Ice Lake) costs 72% more, and the r6i.32xlarge, the r6id.32xlarge and the r6in.32xlarge also sit above it.
It is size 9 of 10 in the r6a series. Stepping up to the r6a.48xlarge gives 192 vCPUs and 1536 GiB for $2,649 more a month. Dropping to the r6a.24xlarge saves $1,325 a month.
