Practical Cluster Applications of Group Communication
Yair Amir, Yan Gu, Theo Schlossnagle, Jonathan Stanton · 2000
Group communication systems are used to build faulttolerant and replicated services. However, they also can be very useful for building tools that support a highly available web cluster, or help manage a large collection of machines. This paper explores the features of one particular Group communication system called Spread TM that are useful in this environment and describes two specific applications that we built and actively use. These applications are a distributed system logging tool and an IP based high availability fail-over tool for clusters. 1.
