Analysis
The m5a.4xlarge is a general purpose instance in the m5a series with 16 vCPUs and 64 GiB of memory on AMD EPYC 7571 (up to 2.5 GHz), which makes it balanced at 4 GiB of memory per vCPU.
Running it in Mumbai instead of São Paulo saves $482 a month per instance: $0.4440/hour against $1.10/hour, a 149% spread.
It is the cheapest of the 5 processor variants AWS sells at this size and generation. The m5n.4xlarge on Intel Xeon Platinum 8259 (Cascade Lake) costs 38% more, and the m5.4xlarge, the m5ad.4xlarge and the m5d.4xlarge also sit above it.
At $0.6880/hour on demand in US East (N. Virginia), about $502 a month, the m5a.4xlarge is one of the cheaper ways to buy general purpose capacity: only 14% of the 354 current general purpose types cost less per vCPU-hour than its $0.0430.
Reserving it for a year with no upfront payment cuts the Linux rate to $0.4330/hour, which beats on demand once it runs more than 63% of the time; three years brings it to $0.2970/hour, 57% below on demand. Windows Server roughly doubles the bill at $1.42/hour, because the licence is charged per vCPU.
It is size 4 of 8 in the m5a series. Stepping up to the m5a.8xlarge gives 32 vCPUs and 128 GiB for $502 more a month. Dropping to the m5a.2xlarge saves $251 a month.
