Scaling real-time AI agents with session-aware load balancing
↗
Standard infrastructure lacks visibility into whether a stream is an active conversation or an idle connection, which risks routing traffic to servers that appear underutilized but are actually at capacity. Builders must implement session lifecycle tracking directly in the backend runtime to ensure accurate load reporting and prevent overloads during concurrent processing spikes.

Traditional metrics like queries-per-second and CPU usage are deceptive for real-time AI because they miss the resource commitment of ongoing conversations and the sudden spikes from concurrent speech processing.
Generic load balancers cannot distinguish between active user conversations, idle listeners, and background noise within bidirectional streaming protocols.
Accurate load balancing requires the backend service to track active sessions internally, incrementing a counter when a stream starts and decrementing it in a finally block to handle timeouts and cancellations.
