systems). The goal of confining the reboot to fine-grain components is threefold: to reduce the amount of time it takes for the system to return to service, to minimize the failure's disruption to the system and its users, and to preserve as much in-memory application data as possible. The concept was proposed in 2001 by George Candea and Armando Fox, while the former was a graduate student at
