m5a.2xlarge

The m5a.2xlarge is a general-purpose AWS EC2 instance: 8 vCPU and 32 GiB of memory, 4.00 GiB per vCPU. In the name, "m" is the general-purpose line, "5" is the generation, "a" marks AMD processors and "2xlarge" is the size within the m5a family. It runs on AMD EPYC 7571 at 2.5 GHz, and AWS introduced it in November 2018. AWS has since shipped m6a, m7a, m8a and m9g; m6a.2xlarge is the direct replacement at this size, scoring 169,106 CoreMark/s against this instance's 101,266 — roughly 67% more throughput for the same vCPU count. Rackspace Spot's gp.vs1.xlarge is a like-for-like substitute at 8 vCPU and 32 GiB, about 91% below the US East (N. Virginia) on-demand rate.

When to use it
Good for
  • ●Development, staging and CI environments
  • ●Small to mid-size relational databases
  • ●Backend services with no single dominant resource
  • ●Workloads that fit inside 32 GiB of RAM
  • ●Parallel work that can occupy 8 vCPU
  • ●Network-heavy services — AWS rates this size at Up to 10 Gigabit
Avoid if
  • ●Starting a new deployment. m6a.2xlarge is the newer generation at this size.
  • ●The working set needs more than 32 GiB of RAM
  • ●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
  • ●Sustained full-core CPU load. A compute-optimized family costs less per unit of work.
$251/mo on AWS on-demand against $23/mo on Rackspace Spot for the equivalent — market-priced, not list-priced.
  • 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.
