Analysis
The r5a.large is a memory optimized instance in the r5a series with 2 vCPUs and 16 GiB of memory on AMD EPYC 7571 (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 $79.57 a month per instance: $0.0720/hour against $0.1810/hour, a 151% spread.
At $0.1130/hour on demand in US East (N. Virginia), about $82.49 a month, the r5a.large is one of the cheaper ways to buy memory optimized capacity: only 5% of the 385 current memory optimized types cost less per vCPU-hour than its $0.0565.
It is the cheapest of the 5 processor variants AWS sells at this size and generation. The r5b.large on Intel Xeon Platinum 8259 (Cascade Lake) costs 32% more, and the r5.large, the r5ad.large and the r5d.large also sit above it.
Reserving it for a year with no upfront payment cuts the Linux rate to $0.0710/hour, which beats on demand once it runs more than 63% of the time; three years brings it to $0.0490/hour, 57% below on demand. Windows Server roughly adds 81% to the bill at $0.2050/hour, because the licence is charged per vCPU.
It is the smallest of the 8 r5a sizes. Stepping up to the r5a.xlarge gives 4 vCPUs and 32 GiB for $82.49 more a month.
