AI Hardware and Infra Sizing Guide

Plan and size AI infrastructure for training and inference with the right GPUs/CPUs, throughput/SLA targets, autoscaling, and cost controls.

Correct sizing balances performance, availability, and cost. Use workload characterization, benchmarking, and scaling policies to choose hardware and architectures.

GPUs by memory and throughput; NVLink vs PCIe; HBM considerations.

CPUs for lightweight or edge models; accelerators/NPUs where available.

Storage: SSD vs object; cache hierarchy; network throughput.

Autoscaling on tokens/QPS; batching; dynamic batching.

Caching (embeddings/responses); KV cache reuse.

Model tiering: small/medium/large by use case.

Frequently asked questions

What is observability and what metrics should I be monitoring?

Set up observability: utilization, latency, cost per request.

How frequently should I conduct load testing and capacity planning?

Run load tests; capacity plan quarterly; revisit with model changes.

What strategies can I employ to avoid overprovisioning resources?

Overprovisioning: enforce budgets; right-size; turn off idle.

How do I address underprovisioning issues, such as sudden traffic spikes?

Underprovisioning: load tests; surge buffers; graceful degradation.
