High-throughput local LLM architecture guide combining vLLM PagedAttention virtual memory, Prefill-Decode disaggregation over RoCE v2/NVLink, and a custom Go API Gateway with SHA256 prompt prefix context-affinity routing, zero-allocation SSE streaming, and 71% cost savings over SaaS APIs.

High-Throughput Local LLM Infrastructure: Architecting a Distributed Go API Gateway for vLLM & PagedAttention Clusters Executive Summary & Architecture Overview Operating open-weight Large Language Models (e.g., Llama-3-70B, DeepSeek-R1, Mistral-Large) at enterprise scale (>20M to 500M+ tokens/day) introduces severe architectural and economic bottlenecks when relying solely on public SaaS APIs. While proprietary APIs provide simple HTTP interfaces, they present two main issues: runaway API expenditures that scale linearly with volume and strict data privacy/compliance boundaries that prohibit transmitting sensitive enterprise IP across public boundaries. ...
