Analysis
The r7g.xlarge is a memory optimized instance in the r7g series with 4 vCPUs and 32 GiB of memory on AWS Graviton3 (up to 2.5 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Running it in Mumbai instead of São Paulo saves $139 a month per instance: $0.1502/hour against $0.3409/hour, a 127% spread.
At $0.2142/hour on demand in US East (N. Virginia), about $156 a month, the r7g.xlarge is one of the cheaper ways to buy memory optimized capacity: only 3% of the 385 current memory optimized types cost less per vCPU-hour than its $0.0536.
It is the cheapest of the 5 processor variants AWS sells at this size and generation. The r7iz.xlarge on Intel Xeon Scalable (Sapphire Rapids) costs 74% more, and the r7i.xlarge, the r7gd.xlarge and the r7a.xlarge also sit above it.
Compared with the previous generation, it costs 6.2% more than the r6g.xlarge on AWS Graviton2 ($9.20 more a month per instance), in exchange for the newer processor. The newer r8g.xlarge on AWS Graviton4 is 10% dearer at $0.2356/hour.
It is size 3 of 8 in the r7g series. Stepping up to the r7g.2xlarge gives 8 vCPUs and 64 GiB for $156 more a month. Dropping to the r7g.large saves $78.18 a month.
