Production LLM Inference on Kubernetes
Deep production knowledge for engineers running LLM inference on self-managed Kubernetes. vLLM optimization, gateway architecture, observability, debugging, and cost modeling, all from real H100 production deployments. Lifetime updates included.
What you'll learn
Curriculum
8 modules · 32 lessonsThe Production Inference Stack
The two-layer architecture that every production LLM stack converges on, the lifecycle of a single request, and the metrics that actually predict production health.
Single-GPU Optimization with vLLM
vLLM configuration, prefill vs decode dynamics, KV cache management, quantization depth, and the batching and admission behaviour that decides throughput against latency on one GPU.
Serving Models That Do Not Fit One GPU
Sizing, sharding, multi-host replicas, disaggregated prefill and decode, and cache beyond a single engine.
Gateway Architecture on Kubernetes
Why you need a gateway, streaming APIs done right, routing and failover patterns, and multi-tenant gateway design on Kubernetes.
Serving at Fleet Scale
Routing on state rather than health, the decode-side throughput lever most platforms never pull, and the SLOs that make any of it measurable.
Operating Engines Beyond vLLM
Running SGLang and Triton in production once the engine choice is already made: the operational differences, the tuning surface, and what consolidation costs.
Observability & Debugging
How to actually see what your inference stack is doing: separating gateway and engine signals, debugging tail latency, chasing throughput regressions, and a playbook for the 3am pages.
Cost Modeling at Scale
The math that turns 'feels expensive' into a real budget. Cost per token, concurrency economics, and a playbook of optimizations that actually cut the bill.
