i7i.8xlargeAWS Pricing, Specs & Benchmarks

The i7i family is a generation-7 storage-optimized (NVMe SSD) line running on Intel Xeon (x86_64) — the explicit-Intel variant in a generation that also ships AMD and Graviton options. i7i.8xlarge provides 32 vCPUs and 256GB of RAM (a 1:8 vCPU-to-memory ratio), priced at $3.0202/hr On-Demand — about $2174.54 per month at 24×7 utilization.

Storage-optimized (NVMe SSD) instances are sized for NoSQL databases (Cassandra, ScyllaDB), search engines (Elasticsearch), transactional databases needing very low storage latency, and large log-ingestion pipelines. If your workload doesn't match that profile — for example, if you're running a memory-bound app on a compute-optimized instance, or a CPU-pegged batch job on a burstable t-series — you'll likely pay for capacity you can't use or run into bottlenecks you didn't anticipate. The pages for sibling families (linked further down) cover those alternatives in detail.

In the AWS instance-naming convention, the digit after the series letter is the generation — higher is newer. This appears to be one of AWS's newer generations in the series, so for most fresh workloads it's a reasonable default within its category.

Pricing varies by region (sometimes meaningfully — the gap between the cheapest and most expensive AWS region for the same SKU is often 15–30%). The regional pricing table further down shows where i7i.8xlarge is cheapest today, both On-Demand and Spot. Spot pricing for i7i.8xlarge is currently $1.0003/hr — roughly 67% off On-Demand — which makes the instance viable for fault-tolerant batch jobs, CI fleets, and any workload that can tolerate interruption with short notice.
