ROSE, a modular distributed operating system that provides support for building reliable applications, is designed and implemented. Failure detection capabilities are provided by a failure detection server. Configuration objects can be used to capture the relationship among multiple processes that cooperate to replicate certain resources. Replicated address space (RAS) objects, whose content is accessible with a high probability despite hardware failures, can be used to increase data availability. Finally, a resistant process (RP) abstraction allows user processes to survive hardware failures with minimal interruption. Two different implementations of RP are provided: one checkpoints the information about its state in an RAS object periodically; the other uses replicated execution by executing the same code in different nodes at the same time
