Analysis
The inf1.2xlarge is a machine learning asic instances instance in the inf1 series with 8 vCPUs and 16 GiB of memory on Intel Xeon Platinum 8275CL (Cascade Lake), which makes it compute-heavy at 2 GiB of memory per vCPU.
Nothing else with 8 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.
At $0.3620/hour on demand in US East (N. Virginia), about $264 a month, the inf1.2xlarge is one of the cheaper ways to buy machine learning asic instances capacity: only 4% of the 13 current machine learning asic instances types cost less per vCPU-hour than its $0.0452.
Running it in N. Virginia instead of São Paulo saves $172 a month per instance: $0.3620/hour against $0.5980/hour, a 65% spread.
It is size 2 of 4 in the inf1 series. Stepping up to the inf1.6xlarge gives 24 vCPUs and 48 GiB for $597 more a month. Dropping to the inf1.xlarge saves $97.82 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.
