i4i.2xlarge

The i4i.2xlarge pairs 8 vCPU with 64 GiB of RAM, the 8.00 GiB-per-vCPU ratio that marks a storage-optimized instance. In the name, "i" is I/O, meaning local storage, "4" is the generation, "i" marks Intel processors and "2xlarge" is the size within the i4i family. It runs on Intel Xeon 8375C (Ice Lake) at 3.5 GHz, and AWS introduced it in April 2022. AWS has since shipped i7i and i8g; i7i.2xlarge is the direct replacement at this size, scoring 158,290 CoreMark/s against this instance's 138,865 — roughly 14% more throughput for the same vCPU count. mh.vs1.xlarge on Rackspace Spot lines up one-for-one: 8 vCPU and 64 GiB, about 95% below the US East (N. Virginia) on-demand rate.

Match qualityNo local disk

i4i.2xlarge comes with 1 × 1,875 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
  • ●Data warehousing and log processing
  • ●Distributed file systems and search indexes
  • ●Transactional databases with heavy random I/O
  • ●Workloads that fit inside 64 GiB of RAM
  • ●Jobs that want 1 × 1,875 GB of local NVMe scratch space
  • ●Network-heavy services — AWS rates this size at Up to 12 Gigabit
Avoid if
  • ●Starting a new deployment. i7i.2xlarge is the newer generation at this size.
  • ●The working set needs more than 64 GiB of RAM
  • ●GPU or FPGA acceleration is needed
  • ●Workloads that never touch local disk. The instance-store premium is wasted.
  • ●More than 8.00 GiB of RAM per vCPU is needed — that ratio is fixed for the whole family
Stop overpaying AWS. This compute costs $501/mo on AWS vs $23/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.
