m5.4xlarge

The m5.4xlarge 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, "5" is the generation and "4xlarge" is the size within the m5 family. It runs on Intel Xeon Platinum 8175 at 3.1 GHz, and AWS introduced it in November 2017. AWS has since shipped m6i, m7i, m8i and m9g; m6i.4xlarge is the direct replacement at this size, scoring 266,024 CoreMark/s against this instance's 235,271 — roughly 13% more throughput for the same vCPU count. 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
  • ●Web and application servers with mixed CPU and memory demand
  • ●Microservices and container fleets
  • ●Development, staging and CI environments
  • ●Workloads that fit inside 64 GiB of RAM
  • ●Parallel work that can occupy 16 vCPU
  • ●Network-heavy services — AWS rates this size at Up to 10 Gigabit
Avoid if
  • ●Starting a new deployment. m6i.4xlarge is the newer generation at this size.
  • ●The working set needs more than 64 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 $561/mo on AWS vs $30/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.
