m6id.xlarge

m6id.xlarge is AWS's general-purpose EC2 size at 4 vCPU and 16 GiB. In the name, "m" is the general-purpose line, "6" is the generation, "id" marks Intel processors and local NVMe storage and "xlarge" is the size within the m6id family. It runs on Intel Xeon 8375C (Ice Lake) at 3.5 GHz, and AWS introduced it in May 2022. AWS has since shipped m7i, m8id and m9g; m7i.xlarge is the direct replacement at this size, scoring 89,171 CoreMark/s against this instance's 65,798 — roughly 36% 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, about 95% below the US East (N. Virginia) on-demand rate.

Match qualityNo local disk

m6id.xlarge comes with 1 × 237 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
  • ●Queue workers and scheduled jobs
  • ●Web and application servers with mixed CPU and memory demand
  • ●Microservices and container fleets
  • ●Workloads that fit inside 16 GiB of RAM
  • ●Jobs that want 1 × 237 GB of local NVMe scratch space
  • ●Network-heavy services — AWS rates this size at Up to 12.5 Gigabit
Avoid if
  • ●Starting a new deployment. m7i.xlarge is the newer generation at this size.
  • ●The working set needs more than 16 GiB of RAM
  • ●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
  • ●Sustained full-core CPU load. A compute-optimized family costs less per unit of work.
Stop overpaying AWS. This compute costs $173/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.
