i3.2xlarge

The i3.2xlarge is a storage-optimized AWS EC2 instance: 8 vCPU and 61 GiB of memory, 7.63 GiB per vCPU. In the name, "i" is I/O, meaning local storage, "3" is the generation and "2xlarge" is the size within the i3 family. It runs on Intel Xeon E5-2686 v4 (Broadwell) at 2.3 GHz, and AWS introduced it in November 2016. AWS has since shipped i4i, i7i and i8g; i4i.2xlarge is the direct replacement at this size. Rackspace Spot's mh.vs1.xlarge is a like-for-like substitute at 8 vCPU and 64 GiB, about 95% below the US East (N. Virginia) on-demand rate.

Match qualityNo local disk

i3.2xlarge comes with 1 × 1,900 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
  • ●NoSQL stores such as Cassandra, ScyllaDB and MongoDB
  • ●Data warehousing and log processing
  • ●Distributed file systems and search indexes
  • ●Workloads that fit inside 61 GiB of RAM
  • ●Jobs that want 1 × 1,900 GB of local NVMe scratch space
  • ●Network-heavy services — AWS rates this size at Up to 10 Gigabit
Avoid if
  • ●Starting a new deployment. i4i.2xlarge is the newer generation at this size.
  • ●The working set needs more than 61 GiB of RAM
  • ●GPU or FPGA acceleration is needed
  • ●Workloads that never touch local disk. The instance-store premium is wasted.
  • ●More than 7.63 GiB of RAM per vCPU is needed — that ratio is fixed for the whole family
Stop overpaying AWS. This compute costs $456/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.
