Analysis
The r6a.2xlarge is a memory optimized instance in the r6a series with 8 vCPUs and 64 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.2xlarge on AMD EPYC 7571, so the move up a generation is free. The newer r7a.2xlarge on AMD EPYC 9R14 is 34% dearer at $0.6086/hour.
Running it in Mumbai instead of Frankfurt saves $191 a month per instance: $0.2860/hour against $0.5472/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.2xlarge on AWS Graviton2 costs $0.4032/hour, 11% less ($36.79 a month), though switching means rebuilding software for arm64. The other variants are the r6gd.2xlarge at $0.4608, the r6i.2xlarge at $0.5040 and the r6id.2xlarge at $0.6048.
At $0.4536/hour on demand in US East (N. Virginia), about $331 a month, the r6a.2xlarge 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 3 of 10 in the r6a series. Stepping up to the r6a.4xlarge gives 16 vCPUs and 128 GiB for $331 more a month. Dropping to the r6a.xlarge saves $166 a month.
