The hs1.8xlarge pairs 16 vCPU with 117 GiB of RAM, the 7.31 GiB-per-vCPU ratio that marks a storage-optimized instance. In the name, "1" is the generation and "8xlarge" is the size within the hs1 family. It runs on Intel Xeon E5-2650 at 2 GHz, and AWS introduced it in December 2012. hs1 is the current generation of the hs family, so there is no newer AWS size to migrate to. mh.vs1.2xlarge on Rackspace Spot lines up one-for-one: 16 vCPU and 128 GiB.

When to use it
Good for
●Elasticsearch and OpenSearch data nodes
●NoSQL stores such as Cassandra, ScyllaDB and MongoDB
●Data warehousing and log processing
●Workloads that fit inside 117 GiB of RAM
●Parallel work that can occupy 16 vCPU
●Network-heavy services — AWS rates this size at 10 Gigabit
Avoid if
●The working set needs more than 117 GiB of RAM
●Local NVMe or instance-store disk is a hard requirement
●GPU or FPGA acceleration is needed
●Workloads that never touch local disk. The instance-store premium is wasted.
●More than 7.31 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.
