m4.4xlarge

The m4.4xlarge pairs 16 vCPU with 64 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, "4" is the generation and "4xlarge" is the size within the m4 family. It runs on Intel Xeon E5-2676 v3 (Haswell) at 2.4 GHz, and AWS introduced it in June 2015. AWS has since shipped m5, m6i, m7i and m8i; m5.4xlarge is the direct replacement at this size. gp.vs1.2xlarge on Rackspace Spot lines up one-for-one: 16 vCPU and 64 GiB, about 95% below the US East (N. Virginia) on-demand rate.

When to use it
Good for
  • ●Backend services with no single dominant resource
  • ●Queue workers and scheduled jobs
  • ●Web and application servers with mixed CPU and memory demand
  • ●Workloads that fit inside 64 GiB of RAM
  • ●Parallel work that can occupy 16 vCPU
Avoid if
  • ●Starting a new deployment. m5.4xlarge is the newer generation at this size.
  • ●The working set needs more than 64 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
  • ●The work is single-threaded. Most of these 16 vCPU would sit idle.
  • ●Local NVMe or instance-store disk is a hard requirement
m4.4xlarge runs $584/mo on AWS on-demand. The equivalent on Rackspace Spot: $30/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.
