Analysis
The u-3tb1.56xlarge is a memory optimized instance in the u-3tb1 series with 224 vCPUs and 3072 GiB of memory on Intel Xeon Scalable (Skylake) (up to 2.1 GHz), which makes it very memory-heavy at 13.71 GiB of memory per vCPU.
Running it in N. Virginia instead of São Paulo saves $11,862 a month per instance: $27.30/hour against $43.55/hour, a 60% spread. It is not offered in London and Mumbai, so plan around that if you need a presence there.
Per vCPU it is one of the dearer memory optimized types: 91% of the 385 current types in the family cost less than its $0.1219 per vCPU-hour. The premium mostly pays for the extra memory per vCPU. On demand it is $27.30/hour in US East (N. Virginia), or $19,929 for a 730-hour month.
Reserving it for a year with no upfront payment cuts the Linux rate to $16.82/hour, which beats on demand once it runs more than 62% of the time; three years brings it to $8.77/hour, 68% below on demand. Windows Server roughly adds 38% to the bill at $37.60/hour, because the licence is charged per vCPU.
Storage is EBS only. Network: 50 Gigabit.
