Analysis
The r6a.large is a memory optimized instance in the r6a series with 2 vCPUs and 16 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.large on AMD EPYC 7571, so the move up a generation is free. The newer r7a.large on AMD EPYC 9R14 is 34% dearer at $0.1522/hour.
Running it in Mumbai instead of Frankfurt saves $47.67 a month per instance: $0.0715/hour against $0.1368/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.large on AWS Graviton2 costs $0.1008/hour, 11% less ($9.20 a month), though switching means rebuilding software for arm64. The other variants are the r6gd.large at $0.1152, the r6i.large at $0.1260 and the r6id.large at $0.1512.
At $0.1134/hour on demand in US East (N. Virginia), about $82.78 a month, the r6a.large 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 smallest of the 10 r6a sizes. Stepping up to the r6a.xlarge gives 4 vCPUs and 32 GiB for $82.78 more a month.
