Analysis
The inf1.xlarge is a machine learning asic instances instance in the inf1 series with 4 vCPUs and 8 GiB of memory on Intel Xeon Platinum 8275CL (Cascade Lake), which makes it compute-heavy at 2 GiB of memory per vCPU.
The newer inf2.xlarge on AMD EPYC 7R13 is 233% dearer at $0.7582/hour.
Nothing else with 4 vCPUs and similar memory is cheaper: among 2 current same-shape types it has the lowest on-demand price.
It carries 1 GPU, so most of the price is the accelerator rather than the CPUs. Storage is EBS only. Network: Up to 25 Gigabit.
Running it in N. Virginia instead of São Paulo saves $109 a month per instance: $0.2280/hour against $0.3770/hour, a 65% spread.
It is the smallest of the 4 inf1 sizes. Stepping up to the inf1.2xlarge gives 8 vCPUs and 16 GiB for $97.82 more a month. Unit price is not flat across the series ($0.0452 to $0.0570 per vCPU-hour), so the size changes the rate you pay.
On demand it costs $0.2280/hour in US East (N. Virginia), $166 a month if left running, which puts it mid-table for machine learning asic instances types at the 27th percentile per vCPU ($0.0570 per vCPU-hour) and the 65th percentile per GiB ($0.0285 per GiB-hour).
