Abstract
This paper identifies key problem areas for the fault-tolerant community to address. Changes in technology, expectation of society, and needs of the market pressure the design point for fault-tolerance in their own special manner. A developer, who has only a finite set of resources and limited time, responds to these pressures with a set of priorities. I believe that the top five challenges, which ultimately drive the exploitation of fault-tolerant technology are: (1) Shipping a product on schedule, (2) Reducing unavailability, (3) Non-disruptive change management, (4) Human fault-tolerance, (5) All over again in the distributed world. Each of these are discussed to explore their influence on the choice for fault-tolerance. Understanding them is key to guide research investment and maximize its derivatives.
