Global AI routing with <1% overhead on multi-cluster GKE Inference Gateway

Google Cloud details a multi-cluster GKE Inference Gateway that routes global AI traffic with under 1% overhead. The system manages 17,000 nodes across three regions, achieving near-linear throughput scaling for large MoE models. This approach allows developers to aggregate fragmented accelerator capacity into a single high-availability endpoint, improving resource utilization for distributed inference workloads.
