m8in.xlarge

m8in.xlarge is AWS's general-purpose EC2 size at 4 vCPU and 16 GiB. In the name, "m" is the general-purpose line, "8" is the generation, "in" marks Intel processors and enhanced networking and "xlarge" is the size within the m8in family. It runs on Intel Xeon Scalable (Granite Rapids) at 3.9 GHz, and AWS introduced it in April 2026. AWS has since shipped m9g; m9g.xlarge is the direct replacement at this size, scoring 145,914 CoreMark/s against this instance's 97,205 — roughly 50% more throughput for the same vCPU count. On Rackspace Spot the same shape is gp.vs2.large — 4 vCPU, 16 GiB, matched on both dimensions, $0.334/hr on AWS in US East (N. Virginia), from $0.011/hr on Rackspace Spot.

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
  • ●Small, steady services that do not need more than 4 vCPU
  • ●Network-heavy services — AWS rates this size at Up to 30 Gigabit
Avoid if
  • ●The working set needs more than 16 GiB of RAM
  • ●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
  • ●GPU or FPGA acceleration is needed
m8in.xlarge runs $244/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.
