Abstract: A distributed computing system can be operated in a fault tolerant manner using a set of computing devices. A set of computing devices can tolerate a number of failures by implementing identical replicas of a state machine and selecting proposals. The set of computing devices participating in the distributed computing system by hosting replicas can be modified by adding or removing a computing device from the set, or by specifying particular computing devices for participation. Changing the participating computing devices in the set increases fault tolerance by replacing defective devices with operational devices, or by increasing the amount of redundancy in the system.

Abstract: A mechanism that enables a nondeterministic client-server application to be run as a replicated state machine without requiring the application to be modified. A replicated state machine substrate is utilized to coordinate the execution of multiple virtual machine monitors, each of which runs an identical copy of an operating system and server application. The virtual machine monitors each act as deterministic state machines, virtualizing state machine characteristics and behaviors.
