Scaling Real-Time AI Agents: Introducing Session-Aware Load Balancing

rseroter · x · 2026-08-05

The Google Developers Blog explores the engineering challenges of scaling real-time AI agents. Unlike ephemeral, stateless traditional API requests, real-time AI handles continuous bidirectional streams (like audio chunks and synthesized speech) and must instantly reset context if a user interrupts. Consequently, traditional load balancing relying solely on QPS and CPU usage fails; systems must shift to session-aware load balancing to accurately track and manage the resources consumed by these long-lived, stateful streams.
