Today's emerging needs (Internet of Things applications, Network Function Virtualization
services, Mobile Edge computing, etc.) are challenging the classic approach of deploying a …

Online applications now routinely replicate their data at multiple sites around the world. In
this paper we present Atlas, the first state-machine replication protocol tailored for such …

This paper proposes CAESAR, a novel multi-leader Generalized Consensus protocol for
geographically replicated sites. The main goal of CAESAR is to overcome one of the major …

Modern web applications replicate their data across the globe and require strong
consistency guarantees for their most critical data. These guarantees are usually provided …

New multi-leader consensus protocols leverage the Generalized Consensus specification to
enable low latency, even load balancing, and high parallelism. However, these protocols …

Paxos, the de facto standard approach to solving distributed consensus, operates in two
phases, each of which requires an intersecting quorum of nodes. Multi-Paxos reduces this to …

Modern Internet services commonly replicate critical data across several geographical
locations using state-machine replication (SMR). Due to their reliance on a leader replica …

Atomic multicast is an important building block in the architecture of scalable and highly
available services. Atomic multicast reliably propagates and orders messages addressed to …

With the reduced cost of hardware due to technological advancements and efficient elastic
networks, distributed systems size is increasing to meet better availability requirements …

Many current online services need to serve clients distributed across geographic areas.
These systems are subject to stringent availability and performance requirements. In order to …
