r6i.2xlarge

The r6i.2xlarge pairs 8 vCPU with 64 GiB of RAM, the 8.00 GiB-per-vCPU ratio that marks a memory-optimized instance. In the name, "r" stands for RAM, "6" is the generation, "i" marks Intel processors and "2xlarge" is the size within the r6i family. It runs on Intel Xeon 8375C (Ice Lake) at 3.5 GHz, and AWS introduced it in November 2021. AWS has since shipped r7i, r8i and r9g; r7i.2xlarge is the direct replacement at this size, scoring 187,215 CoreMark/s against this instance's 136,694 — roughly 37% more throughput for the same vCPU count. mh.vs2.xlarge on Rackspace Spot lines up one-for-one: 8 vCPU and 64 GiB, about 94% below the US East (N. Virginia) on-demand rate.

When to use it
Good for
  • ●OLAP and business intelligence query engines
  • ●Real-time analytics over hot datasets
  • ●Database instances that keep the working set in RAM
  • ●Workloads that fit inside 64 GiB of RAM
  • ●Parallel work that can occupy 8 vCPU
  • ●Network-heavy services — AWS rates this size at Up to 12.5 Gigabit
Avoid if
  • ●Starting a new deployment. r7i.2xlarge is the newer generation at this size.
  • ●The working set needs more than 64 GiB of RAM
  • ●CPU-bound work. You are paying for memory this workload will not use.
  • ●More than 8.00 GiB of RAM per vCPU is needed — that ratio is fixed for the whole family
  • ●Local NVMe or instance-store disk is a hard requirement
  • ●GPU or FPGA acceleration is needed
r6i.2xlarge runs $368/mo on AWS on-demand. The equivalent on Rackspace Spot: $23/mo.
  • 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.
