h1.4xlarge

h1.4xlarge is AWS's storage-optimized EC2 size at 16 vCPU and 64 GiB. In the name, "h" is dense HDD storage, "1" is the generation and "4xlarge" is the size within the h1 family. It runs on Intel Xeon E5-2686 v4 (Broadwell) at 2.3 GHz, and AWS introduced it in November 2017. h1 is the current generation of the h family, so there is no newer AWS size to migrate to. On Rackspace Spot the same shape is gp.vs1.2xlarge — 16 vCPU, 64 GiB, matched on both dimensions, $0.936/hr on AWS in US East (N. Virginia), from $0.041/hr on Rackspace Spot.

Match qualityNo local disk

h1.4xlarge comes with 2 × 2,000 GB HDD 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
  • ●Distributed file systems and search indexes
  • ●Transactional databases with heavy random I/O
  • ●Streaming ingest that spools to local disk
  • ●Workloads that fit inside 64 GiB of RAM
  • ●Jobs that want 2 × 2,000 GB of local SSD scratch space
  • ●Network-heavy services — AWS rates this size at Up to 10 Gigabit
Avoid if
  • ●The working set needs more than 64 GiB of RAM
  • ●More than 4.00 GiB of RAM per vCPU is needed — that ratio is fixed for the whole family
  • ●The work is single-threaded. Most of these 16 vCPU would sit idle.
  • ●GPU or FPGA acceleration is needed
  • ●Workloads that never touch local disk. The instance-store premium is wasted.
Stop overpaying AWS. This compute costs $683/mo on AWS vs $30/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.
