Fail-fast (original) (raw)
In systems design, a fail-fast system is one which immediately reports at its interface any condition that is likely to indicate a failure. Fail-fast systems are usually designed to stop normal operation rather than attempt to continue a possibly flawed process. Such designs often check the system's state at several points in an operation, so any failures can be detected early. The responsibility of a fail-fast module is detecting errors, then letting the next-highest level of the system handle them.

(en) Fail-Fast (sinngemäß „schneller Abbruch“) bezeichnet die Eigenschaft eines Systems, Fehler frühzeitig zu erkennen. Ein Fail-Fast-System ist so konzipiert, dass es an seinen Schnittstellen Fehler oder Zustände, die zu Fehlern führen, erkennt und aufzeigt. Üblicherweise beenden sich Fail-Fast-Systeme im Fehlerfall selbst und versuchen nicht, mit dem Fehler weiterzuarbeiten. Fail-Fast-Systeme überprüfen oft nicht allein die Schnittstellen, sondern auch den Zustand eines Systems an verschiedenen Stellen, um Fehler frühzeitig zu erkennen. Dabei wird die Fehlerbehandlung an den Aufrufer des Systems weiterdelegiert – kann dieser es in einen sicheren Zustand versetzen, so spricht man von Fail-Safe. (de) |
