x8aedz.3xlarge

Analysis

The x8aedz.3xlarge is a memory optimized instance in the x8aedz series with 12 vCPUs and 384 GiB of memory on AMD EPYC 9R05 (up to Up to 5 GHz), which makes it very memory-heavy at 32 GiB of memory per vCPU.

Running it in Oregon instead of Tokyo saves $1,134 a month per instance: $3.45/hour against $5.01/hour, a 45% spread. It is not offered in N. Virginia, Ohio, Canada Central, São Paulo, London, Frankfurt, Singapore and Sydney, so plan around that if you need a presence there.

Per vCPU it is one of the dearer memory optimized types: 99% of the 385 current types in the family cost less than its $0.2877 per vCPU-hour. The premium mostly pays for the local NVMe disk. On demand it is $3.45/hour in its cheapest tracked region, or $2,520 for a 730-hour month.

It has local instance storage (1 x 950 GB NVMe SSD), which is fast but lost when the instance stops. Network: Up to 18750 Megabit.

It is size 3 of 6 in the x8aedz series. Stepping up to the x8aedz.6xlarge gives 24 vCPUs and 768 GiB for $2,520 more a month. Dropping to the x8aedz.xlarge saves $1,680 a month.

Windows Server roughly adds 16% to the bill at $4.00/hour, because the licence is charged per vCPU.
