m9gd.xlarge

m9gd.xlarge is AWS's general-purpose EC2 size at 4 vCPU and 16 GiB. In the name, "m" is the general-purpose line, "9" is the generation, "gd" marks AWS Graviton (ARM) processors and local NVMe storage and "xlarge" is the size within the m9gd family. It runs on AWS Graviton5 Processor at 3.3 GHz, and AWS introduced it in June 2026. m9gd is the current generation of the m family, so there is no newer AWS size to migrate to. On Rackspace Spot the same shape is gp.vs2.large — 4 vCPU, 16 GiB, matched on both dimensions, $0.251/hr on AWS in US East (N. Virginia), from $0.011/hr on Rackspace Spot.

Match qualityx86 substitution

m9gd.xlarge is Graviton (arm64). Rackspace Spot does not have arm64 servers, so gp.vs2.large is an x86_64 substitute with similar specs.

You will need x86 builds of your container images. Most software rebuilds without changes, but anything with compiled native code needs a real rebuild rather than a retag. Speed per core also differs between the two chips, so it is worth testing before deciding how many nodes to run.

No local diskm9gd.xlarge comes with 1 × 237 GB NVMe SSD attached to the machine. Spot nodes use network storage only, so that disk doesn't come with it. If you were using it as fast scratch space, you'd move to a persistent volume or object storage, which are slower to read.

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 15 Gigabit
Avoid if
  • ●The working set needs more than 16 GiB of RAM
  • ●You cannot rebuild x86-only binaries or vendor images for aarch64
  • ●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 $184/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.
