A framework for highly available services based on group communication
Alan David Fekete, Idit Keidar · 2002
We present a framework for building highly available services. The framework uses group communication to coordinate a collection of servers. Our framework is configurable, in that one can adjust parameters such as the number of servers and the extent to which they are synchronized. We analyze the scenarios that can lead to the service availability being temporarily compromised, and we discuss the tradeoffs that govern the choice of parameters.
