GLOBAL AI ROUTING WITH <1% OVERHEAD ON MULTI-CLUSTER GKE INFERENCE GATEWAY

Summary from the TLDR DevOps newsletter

Google's multi-cluster GKE Inference Gateway pools globally distributed accelerator capacity behind a single endpoint, routing LLM traffic based on live KV-cache utilization rather than round-robin. A 17,000-node benchmark across three regions showed near-linear throughput scaling with less than 1 percent routing overhead and a 99.9 percent success rate.
