m9g.2xlarge

The m9g.2xlarge pairs 8 vCPU with 32 GiB of RAM, the 4.00 GiB-per-vCPU ratio that marks a general-purpose instance. In the name, "m" is the general-purpose line, "9" is the generation, "g" marks AWS Graviton (ARM) processors and "2xlarge" is the size within the m9g family. It runs on AWS Graviton5 Processor at 3.3 GHz, and AWS introduced it in June 2026. m9g is the current generation of the m family, so there is no newer AWS size to migrate to. gp.vs2.xlarge on Rackspace Spot lines up one-for-one: 8 vCPU and 32 GiB, about 92% below the US East (N. Virginia) on-demand rate.

Match qualityx86 substitution

m9g.2xlarge is Graviton (arm64). Rackspace Spot does not have arm64 servers, so gp.vs2.xlarge 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.

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 32 GiB of RAM
  • ●Parallel work that can occupy 8 vCPU
  • ●Network-heavy services — AWS rates this size at Up to 17 Gigabit
Avoid if
  • ●The working set needs more than 32 GiB of RAM
  • ●You cannot rebuild x86-only binaries or vendor images for aarch64
  • ●More than 4.00 GiB of RAM per vCPU is needed — that ratio is fixed for the whole family
  • ●Local NVMe or instance-store disk is a hard requirement
  • ●GPU or FPGA acceleration is needed
  • ●Sustained full-core CPU load. A compute-optimized family costs less per unit of work.
m9g.2xlarge runs $286/mo on AWS on-demand. The equivalent on Rackspace Spot: $23/mo.
  • 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.
