Building global and scalable systems with atomic multicast

Benz, Samuel ; Pedone, Fernando (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO003.

The rise of worldwide Internet-scale services demands large distributed systems. Indeed, when handling several millions of users, it is common to operate thousands of servers spread across the globe. Here, replication plays a central role, as it contributes to improve the user experience by hiding failures and by providing acceptable latency. In this thesis, we claim that atomic multicast,...

High performance deferred update replication

Sciascia, Daniele ; Pedone, Fernando (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2015 ; 2015INFO004.

Replication is a well-known approach to implementing storage systems that can tolerate failures. Replicated storage systems are designed such that the state of the system is kept at several replicas. A replication protocol ensures that the failure of a replica is masked by the rest of the system, in a way that is transparent to its users. Replicated storage systems are among the most...

On multicast primitives in large networks and partial replication protocols

Schiper, Nicolas ; Pedone, Fernando (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2009 ; 2009INFO005.

Recent years have seen the rapid growth of web-based applications such as search engines, social networks, and e-commerce platforms. As a consequence, our daily life activities rely on computers more and more each day. Designing reliable computer systems has thus become of a prime importance. Reliability alone is not sufficient however. These systems must support high loads of client...
