Bringing AI-Aware Traffic Management to Istio: Gateway API Inference Extension Support

The world of AI inference on Kubernetes presents unique challenges that traditional traffic-routing architectures weren’t designed to handle. While Istio has long excelled at managing microservice traffic with sophisticated load balancing, security, and observability features, the demands of Large Language Model (LLM) workloads require specialized functionality. That’s why we’re excited to announce Istio’s support for the Gateway API Inference Extension, bringing intelligent, model-aware and LoRA-aware routing to Istio.
