m5dn.large

The m5dn.large is a general-purpose AWS EC2 instance: 2 vCPU and 8 GiB of memory, 4.00 GiB per vCPU. In the name, "m" is the general-purpose line, "5" is the generation, "dn" marks local NVMe storage and enhanced networking and "large" is the size within the m5dn 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.large is the direct replacement at this size. The nearest Spot node is gp.vs1.large at 4 vCPU and 16 GiB — 2 more vCPU and 8 GiB more memory, about 92% below the US East (N. Virginia) on-demand rate.

Match qualityNo local disk

m5dn.large comes with 1 × 75 GB NVMe SSD attached to the machine. Rackspace Spot nodes use network storage only, so that disk does not come with it.

If you were using the local disk as fast scratch space — temporary files, a local cache, an index — you will need a persistent volume or object storage instead, and both are slower to read. If it was just extra space you never depended on, nothing changes.

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 8 GiB of RAM
  • ●Jobs that want 1 × 75 GB of local NVMe scratch space
  • ●Network-heavy services — AWS rates this size at Up to 25 Gigabit
Avoid if
  • ●Starting a new deployment. m6i.large is the newer generation at this size.
  • ●The working set needs more than 8 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
  • ●GPU or FPGA acceleration is needed
Stop overpaying AWS. This compute costs $99/mo on AWS vs $8/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.
