m8azn.6xlarge

m8azn.6xlarge is AWS's general-purpose EC2 size at 24 vCPU and 96 GiB. In the name, "m" is the general-purpose line, "8" is the generation, "azn" marks AMD processors, a higher clock and enhanced networking and "6xlarge" is the size within the m8azn family. It runs on AMD EPYC 9575F at Up to 5 GHz, and AWS introduced it in February 2026. AWS has since shipped m9g. The closest Spot shape is gp.vs2.2xlarge at 16 vCPU, so this instance maps to 2 of them — 32 vCPU and 128 GiB across the fleet, $2.48/hr on AWS in US East (N. Virginia), from $0.082/hr on Rackspace Spot. Spot delivers compute as managed Kubernetes, so a node pool of that size is the native shape of the answer rather than a workaround — provided the workload scales horizontally.

Match qualityScale-out match

m8azn.6xlarge gives you 24 vCPU and 96 GiB in a single machine. The largest comparable Spot node, gp.vs2.2xlarge, is 16 vCPU and 64 GiB, so the equivalent here is 2 nodes rather than one.

Spot runs as managed Kubernetes, so a 2-node pool is the normal way to run things rather than a workaround. If your workload already sits behind a load balancer, a queue or a scheduler, it spreads across them without changes. If it needs all 24 cores and 96 GiB in one process, it does not.

When to use it
Good for
  • ●Queue workers and scheduled jobs
  • ●Web and application servers with mixed CPU and memory demand
  • ●Microservices and container fleets
  • ●Workloads that fit inside 96 GiB of RAM
  • ●Parallel work that can occupy 24 vCPU
  • ●Network-heavy services — AWS rates this size at 50 Gigabit
  • ●Anything that shards cleanly across 2 nodes, which is how it maps onto Rackspace Spot
Avoid if
  • ●The working set needs more than 96 GiB of RAM
  • ●GPU or FPGA acceleration is needed
  • ●Sustained full-core CPU load. A compute-optimized family costs less per unit of work.
  • ●More than 4.00 GiB of RAM per vCPU is needed — that ratio is fixed for the whole family
  • ●The work is single-threaded. Most of these 24 vCPU would sit idle.
  • ●Local NVMe or instance-store disk is a hard requirement
Stop overpaying AWS. This compute costs $1,809/mo on AWS vs $60/mo on Rackspace Spot.
  • 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.
