Single point of failure

Single point of failure
Un enrutador podría comportarse como un SPOF en una red de comunicación entre computadoras.

Un single point of failure o SPOF ("punto único de fallo") es un componente de un sistema que tras un fallo en su funcionamiento ocasiona un fallo global en el sistema completo, dejándolo inoperante. Un SPOF puede ser un componente de hardware, software o eléctrico. Para garantizar la inexistencia de un SPOF en un sistema, todos sus componentes suelen ser redundados, conformando así un sistema de alta disponibilidad, que garantiza el correcto funcionamiento aún en caso de que alguno de sus componentes falle.
