Answer
Established connections bypass load balancing, causing backend imbalance.
Quick Answer
HTTP/1.1 long-lived connections (WebSocket, gRPC streams, database persistent connections) don't benefit from Service load balancing because one connection goes to one Pod and stays there. All requests on that connection hit the same Pod — no load balancing. Use a service mesh (Istio, Linkerd) for request-level load balancing of persistent connections.
