Analysis
The u-6tb1.56xlarge is a memory optimized instance in the u-6tb1 series with 224 vCPUs and 6144 GiB of memory on Intel Xeon Scalable (Skylake), which makes it very memory-heavy at 27.43 GiB of memory per vCPU.
Per vCPU it is one of the dearer memory optimized types: 93% of the 385 current types in the family cost less than its $0.2072 per vCPU-hour. The premium mostly pays for the very fast networking. On demand it is $46.40/hour in US East (N. Virginia), or $33,875 for a 730-hour month.
It is the smallest of the 2 u-6tb1 sizes. Stepping up to the u-6tb1.112xlarge gives 448 vCPUs and 6144 GiB for $5,983 more a month. Unit price is not flat across the series ($0.1219 to $0.2072 per vCPU-hour), so the size changes the rate you pay.
Running it in N. Virginia instead of São Paulo saves $20,164 a month per instance: $46.40/hour against $74.03/hour, a 60% spread.
Reserving it for a year with no upfront payment cuts the Linux rate to $28.60/hour, which beats on demand once it runs more than 62% of the time; three years brings it to $14.91/hour, 68% below on demand. Windows Server roughly adds 22% to the bill at $56.71/hour, because the licence is charged per vCPU.
