Software fault tolerance is often necessary, but itself can be dangerously error-prone because of the additional effort that must be involved in the programming process. Adding redundancy to programs may increase the size and complexity and thus adversely affect software reliability. Object-oriented programming provides a particularly appropriate framework, based on the theory of abstract data types, for enforcing reliability and controlling complexity. This paper introduces an approach to achieving software fault tolerance in object-oriented systems in a disciplined manner and with reduced cost, and discusses the problem of how to incorporate fault tolerance into concurrent object-oriented computing.
