The i7i.24xlarge is a storage-optimized AWS EC2 instance: 96 vCPU and 768 GiB of memory, 8.00 GiB per vCPU. In the name, "i" is I/O, meaning local storage, "7" is the generation, "i" marks Intel processors and "24xlarge" is the size within the i7i family. It runs on Intel Xeon Scalable (Emerald Rapids) at 3.2 GHz, and AWS introduced it in April 2025. AWS has since shipped i8g; i8g.24xlarge is the direct replacement at this size, scoring 2,969,378 CoreMark/s against this instance's 2,061,413 — roughly 44% more throughput for the same vCPU count. No single Spot node covers 96 vCPU and 768 GiB, so the equivalent is a fleet: 6 × mh.vs1.2xlarge, 96 vCPU and 768 GiB in total, $9.06/hr on AWS in US East (N. Virginia), from $0.126/hr on Rackspace Spot. Spot delivers compute as managed Kubernetes, so a node pool of that size is the native shape of the answer rather than a workaround — provided the workload scales horizontally.
