Analysis
The r6a.xlarge is a memory optimized instance in the r6a series with 4 vCPUs and 32 GiB of memory on AMD EPYC 7R13 (up to 3.6 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
It costs the same as the older r5a.xlarge on AMD EPYC 7571, so the move up a generation is free. The newer r7a.xlarge on AMD EPYC 9R14 is 34% dearer at $0.3043/hour.
Running it in Mumbai instead of Frankfurt saves $95.34 a month per instance: $0.1430/hour against $0.2736/hour, a 91% spread. It is not offered in São Paulo, so plan around that if you need a presence there.
Within the same generation and size, the r6g.xlarge on AWS Graviton2 costs $0.2016/hour, 11% less ($18.40 a month), though switching means rebuilding software for arm64. The other variants are the r6gd.xlarge at $0.2304, the r6i.xlarge at $0.2520 and the r6id.xlarge at $0.3024.
At $0.2268/hour on demand in US East (N. Virginia), about $166 a month, the r6a.xlarge 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 size 2 of 10 in the r6a series. Stepping up to the r6a.2xlarge gives 8 vCPUs and 64 GiB for $166 more a month. Dropping to the r6a.large saves $82.78 a month.
