Abstract
Group communication systems are used to build fault­
tolerant and replicated services. However, they also can be
very useful for building tools that support a highly avail­
able web cluster, or help manage a large collection of ma­
chines. This paper explores the features of one particular
Group communication system called Spread TM that are use­
ful in this environment and describes two specific applica­
tions that we built and actively use. These applications are a
distributed system logging tool and an IP based high avail­
ability fail­over tool for clusters.
1. Introduction
Group communication has been used for many years in
high­availability application domains such as stock markets
