m8azn.xlarge

The m8azn.xlarge pairs 4 vCPU with 16 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, "8" is the generation, "azn" marks AMD processors, a higher clock and enhanced networking and "xlarge" 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; m9g.xlarge is the direct replacement at this size. gp.vs2.large on Rackspace Spot lines up one-for-one: 4 vCPU and 16 GiB, $0.413/hr on AWS in US East (N. Virginia), from $0.011/hr on Rackspace Spot.

When to use it
Good for
  • ●Microservices and container fleets
  • ●Development, staging and CI environments
  • ●Small to mid-size relational databases
  • ●Workloads that fit inside 16 GiB of RAM
  • ●Small, steady services that do not need more than 4 vCPU
  • ●Network-heavy services — AWS rates this size at Up to 40 Gigabit
Avoid if
  • ●The working set needs more than 16 GiB of RAM
  • ●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.
  • ●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 $301/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.
