Incorporating Fault Tolerance into an Autonomic-Computing Environment

Information systems are becoming more and more complicated. First, most of today's information systems are networked stand-alone systems without networking no longer make sense. Second, information systems are growing significantly in size. They include countless resources (such as computing and storage units) and communication facilities, which may be allocated over networks. Third, the territory that information systems cover is becoming obscure, making them boundaryless. Because resources connect to networks and are shared through, say, the Internet across enterprises, a networked information system's scale and configuration can change
