Abstract

This paper reviews the origin of the concept of fault tolerance and the evolution of guidelines for the systematic design of fault-tolerant systems. The current formulation of the guidelines, called a design paradigm, is presented. The problem of using off-the-shelf subsystems in a fault-tolerant system is discussed. In conclusion, an analogy of complex fault-tolerant systems and living organisms is suggested as a means to advance the understanding of fault tolerance.
