The Physics of Queue Failure: Why Bigger Buffers Don't Prevent System Overload

This article challenges a fundamental misconception in system design that plagues engineering teams worldwide. Through queueing theory and Little's Law, the author demonstrates that unbounded queues merely postpone catastrophic failure rather than prevent overload. By highlighting this critical insight, the piece urges engineers to shift from buffer expansion band-aids to implementing proper backpressure mechanisms for truly resilient systems.
