Soon unrelated requests become slow, worker queues stop moving, and healthy features begin returning errors. The original defect may be small, but the system has allowed its effects to spread.</p> <p><strong>Failure containment</strong> is the design practice of limiting how far a fault can propagate. The goal is not to prevent every failure. That is unrealistic. The goal is to make a local failure stay local enough that the rest of the system can continue useful work or fail in a controlled way.</p>
