This chapter addresses the fundamental concepts concerning fault tolerance. It starts by introducing the notion of dependability and discussing why it is difficult to build dependable systems. The evolution of fault-tolerant computing is reviewed, from hardware fault tolerance to distributed software-based fault tolerance. Finally, the chapter introduces the most relevant architectures for fault-tolerant communication and processing, that are later described in detail in the subsequent chapters of this part.
