m5n.xlarge

m5n.xlarge is AWS's general-purpose EC2 size at 4 vCPU and 16 GiB. In the name, "m" is the general-purpose line, "5" is the generation, "n" marks enhanced networking and "xlarge" is the size within the m5n family. It runs on Intel Xeon Platinum 8259 (Cascade Lake) at 3.1 GHz, and AWS introduced it in October 2019. AWS has since shipped m6i, m7i, m8i and m9g; m6i.xlarge is the direct replacement at this size. On Rackspace Spot the same shape is gp.vs1.large — 4 vCPU, 16 GiB, matched on both dimensions, about 95% below the US East (N. Virginia) on-demand rate.

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 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 25 Gigabit
Avoid if
  • ●Starting a new deployment. m6i.xlarge is the newer generation at this size.
  • ●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
  • ●Local NVMe or instance-store disk is a hard requirement
m5n.xlarge runs $174/mo on AWS on-demand. The equivalent on Rackspace Spot: $8/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.
