m8idn.xlarge

The m8idn.xlarge is a general-purpose AWS EC2 instance: 4 vCPU and 16 GiB of memory, 4.00 GiB per vCPU. In the name, "m" is the general-purpose line, "8" is the generation, "idn" marks Intel processors, local NVMe storage and enhanced networking and "xlarge" is the size within the m8idn family. It runs on Intel Xeon Scalable (Granite Rapids) at 3.9 GHz, and AWS introduced it in May 2026. AWS has since shipped m9g; m9g.xlarge is the direct replacement at this size, scoring 145,914 CoreMark/s against this instance's 92,219 — roughly 58% more throughput for the same vCPU count. Rackspace Spot's gp.vs2.large is a like-for-like substitute at 4 vCPU and 16 GiB, $0.382/hr on AWS in US East (N. Virginia), from $0.011/hr on Rackspace Spot.

Match qualityNo local disk

m8idn.xlarge comes with 1 × 237 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
  • ●Small to mid-size relational databases
  • ●Backend services with no single dominant resource
  • ●Queue workers and scheduled jobs
  • ●Workloads that fit inside 16 GiB of RAM
  • ●Jobs that want 1 × 237 GB of local NVMe scratch space
  • ●Network-heavy services — AWS rates this size at Up to 30 Gigabit
Avoid if
  • ●The working set needs more than 16 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
Stop overpaying AWS. This compute costs $279/mo on AWS vs $8/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.
