x8aedz.large

The x8aedz.large pairs 2 vCPU with 64 GiB of RAM, the 32.00 GiB-per-vCPU ratio that marks a memory-optimized instance. In the name, "x" is the extra-memory line, "8" is the generation, "aedz" marks AMD processors, extended capacity, local NVMe storage and a higher clock and "large" is the size within the x8aedz family. It runs on AMD EPYC 9R05 Processor at Up to 5 GHz, and AWS introduced it in December 2025. x8aedz is the current generation of the x family, so there is no newer AWS size to migrate to. mh.vs2.xlarge is the closest Spot shape: 8 vCPU and 64 GiB, so 6 more vCPU and the same memory.

Match qualityNo local disk

x8aedz.large comes with 1 × 158 GB NVMe SSD attached to the machine. Rackspace Spot nodes use network storage only, so that disk does not come with it.

If you were using the local disk as fast scratch space — temporary files, a local cache, an index — you will need a persistent volume or object storage instead, and both are slower to read. If it was just extra space you never depended on, nothing changes.

When to use it
Good for
  • ●Graph and search workloads with large indexes
  • ●In-memory caches such as Redis and Memcached
  • ●Large JVM heaps and application servers that hold state
  • ●Workloads that fit inside 64 GiB of RAM
  • ●Jobs that want 1 × 158 GB of local NVMe scratch space
  • ●Network-heavy services — AWS rates this size at Up to 18.75 Gigabit
Avoid if
  • ●The working set needs more than 64 GiB of RAM
  • ●CPU-bound work. You are paying for memory this workload will not use.
  • ●More than 32.00 GiB of RAM per vCPU is needed — that ratio is fixed for the whole family
  • ●GPU or FPGA acceleration is needed
Rackspace Spot sells spare capacity at market prices. You pay what the market decides, not a list price.
  • Spot sells spare capacity at market prices. It is the cheapest compute on the internet.
  • Prices are set by supply and demand. You pay what the market decides.
  • Compute is delivered as fully managed Kubernetes. All infrastructure is taken care of.
  • Egress costs $0.01/GB after the free allowance. AWS charges $0.09/GB.
