On June 10-11, 1991, a Fault Tolerant Systems Practitioner's Workshop was held at the Software Engineering Institute. The purpose of the workshop was to attempt to identify how fault tolerance is being applied today, why fault tolerance is under used, and what can be done to bring fault tolerant practices into wider use. Attendance at the workshop was limited to a small number of practitioners who had successfully applied fault tolerance in a systems context. This report summarizes the proceedings of the workshop which included a discussion of barriers to the deployment of fault tolerant systems, a summary of the state of the practice, and a discussion of the technology needs of fault tolerance. The report concludes with a discussion of ways the Software Engineering Institute may be able to help bring fault tolerant practices into wider use.
