Homa: Solving AI Networking Latency Bottlenecks

Traditional protocols like TCP and RDMA struggle with modern AI workloads because they treat data as opaque byte streams. Homa, a message-based, receiver-driven protocol, reduces tail latency by over 10x by prioritizing short messages and managing congestion before it occurs.

Architecting Production-Grade LLM Gateways

LLM gateways require a shift from standard API engineering: prioritize per-request fallbacks over circuit breakers, track latency per-route rather than globally, and treat guardrails as unreliable services that require explicit fail-open/closed policies.
