m7i.metal-24xl

m7i.metal-24xl is AWS's general-purpose EC2 size at 96 vCPU and 384 GiB. In the name, "m" is the general-purpose line, "7" is the generation, "i" marks Intel processors and "metal-24xl" is the size within the m7i family. It runs on Intel Xeon Scalable (Sapphire Rapids) at 3.2 GHz, and AWS introduced it in October 2023. AWS has since shipped m8i and m9g; m8a.metal-24xl is the direct replacement at this size, scoring 4,001,667 CoreMark/s against this instance's 2,055,234 — roughly 95% more throughput for the same vCPU count. The closest Spot shape is gp.vs2.2xlarge at 16 vCPU, so this instance maps to 6 of them — 96 vCPU and 384 GiB across the fleet, about 95% below the US East (N. Virginia) on-demand rate. 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 qualityVirtualised, not bare metal

m7i.metal-24xl is a full physical server — no virtualisation layer in the way, direct access to the hardware, and a socket count that licensing can verify.

Rackspace Spot no longer sells bare metal; everything in the catalog is a virtual machine. You get the same cores and memory (6 × gp.vs2.2xlarge, 96 vCPU, 384 GiB), but not the dedicated hardware. If you picked m7i.metal-24xl because you needed the real machine — nested virtualisation, per-socket licensing, low-level profiling — this is not a replacement at any price. If you picked it because it is the biggest m7i, it is the same compute for a lot less.

Runs as a fleetNo single Spot node has 96 vCPU; the largest comparable one has 16. So this runs as 6 nodes. That works if your workload already spreads across machines, and doesn't if one process needs all the cores together.

When to use it
Good for
  • ●Development, staging and CI environments
  • ●Small to mid-size relational databases
  • ●Backend services with no single dominant resource
  • ●Workloads that fit inside 384 GiB of RAM
  • ●Parallel work that can occupy 96 vCPU
  • ●Network-heavy services — AWS rates this size at 37.5 Gigabit
  • ●Anything that shards cleanly across 6 nodes, which is how it maps onto Rackspace Spot
Avoid if
  • ●Starting a new deployment. m8a.metal-24xl is the newer generation at this size.
  • ●The working set needs more than 384 GiB of RAM
  • ●You need dedicated hardware. Rackspace Spot sells virtualised compute only.
  • ●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
$3,532/mo on AWS on-demand against $180/mo on Rackspace Spot for the 6-node equivalent — market-priced, not list-priced.
  • 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.
