x8aedz.large

Analysis

The x8aedz.large is a memory optimized instance in the x8aedz series with 2 vCPUs and 64 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.

Within the same generation and size, the x8g.large on AWS Graviton4 costs $0.1954/hour, 66% less ($277 a month), though switching means rebuilding software for arm64. The other variants are the x8i.large at $0.2188.

Running it in Oregon instead of Tokyo saves $189 a month per instance: $0.5753/hour against $0.8342/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 $0.5753/hour in its cheapest tracked region, or $420 for a 730-hour month.

It has local instance storage (1 x 158 GB NVMe SSD), which is fast but lost when the instance stops. Network: Up to 18750 Megabit.

It is the smallest of the 6 x8aedz sizes. Stepping up to the x8aedz.xlarge gives 4 vCPUs and 128 GiB for $420 more a month.
