The unprecedented growth of data at geographically distributed locations coupled with
tremendous improvement in networking capabilities over the last decade strongly motivate …

Replication is a powerful technique for increasing availability of a distributed service.
Algorithms for replicating distributed services do however face a dilemma: they should be …

In this chapter, we discuss a widely used fault-tolerant data replication model called virtual
synchrony. The model responds to two kinds of needs. First, there is the practical question of …

This paper introduces dual-quorum replication, a novel data replication algorithm designed
to support Internet edge services. Edge services allow clients to access Internet services via …

Chain replication is a new approach to coordinating clusters of fail-stop storage servers. The
approach is intended for supporting large-scale storage services that exhibit high throughput …

For many years, file replication and dereplication in distributed computing environment has
been researched to enhance and optimize the scalability of the entire system. Although …

Replication is a key technique for providing both fault tolerance and availability in distributed
systems. However, managing replicated state, and ensuring that these replicas remain …

An efficient approach for managing replicated data and services is presented. The approach
is based on the fact that the replicas are organized in a logical tree structure. An algorithm …

Many distributed databases employ consensus protocols to ensure that data is replicated in
a strongly-consistent manner on multiple machines despite failures and concurrency …

Over the last two decades, the Internet has evolved from an experimental research network
into a global communication medium. It is now being used on a daily basis by millions of …
