The Complexity of Reliable and Secure Distributed Transactions
The use of transactions in distributed systems dates back to the 70's. The last decade has also seen the proliferation of transactional systems. In the existing transactional systems, many protocols employ a centralized approach in executing a distributed ...
EPFL2018How Fast can a Distributed Transaction Commit?
Rachid Guerraoui, Junxiong Wang
The atomic commit problem lies at the heart of distributed database systems. The problem consists for a set of processes (database nodes) to agree on whether to commit or abort a transaction (agreement property). The commit decision can only be taken if al ...

ACM Press2017Multicloud Resource Allocation
Nowadays our daily life is not only powered by water, electricity, gas and telephony but by "cloud" as well. Big cloud vendors such as Amazon, Microsoft and Google have built large-scale centralized data centers to achieve economies of scale, on-demand res ...
EPFL2017Right On Time Distributed Shared Memory
Rachid Guerraoui, David Kozhaya, Yvonne Anne Pignolet-Oswald
The demand for real-time data storage in distributed control systems (DCSs) is growing. Yet, providing real- time DCS guarantees is challenging, especially when more and more sensor and actuator devices are connected to industrial plants and message loss n ...
2016Scaling Up Mixed Workloads: A Battle of Data Freshness, Flexibility, and Scheduling
Anastasia Ailamaki, Iraklis Psaroudakis
The common "one size does not fit all" paradigm isolates transactional and analytical workloads into separate, specialized database systems. Operational data is periodically replicated to a data warehouse for analytics. Competitiveness of enterprises today ...

Springer International Publishing AG2014Physics-Inspired Methods for Networking and Communications
Advances in statistical physics relating to our understanding of large-scale complex systems have recently been successfully applied in the context of communication networks. Statistical mechanics methods can be used to decompose global system behavior int ...
Ieee-Inst Electrical Electronics Engineers Inc2014Predicting Replicated Database Scalability from Standalone Database Profiling
Willy Zwaenepoel, Sameh Mohamed Elnikety, Emmanuel Cecchet
This paper develops analytical models to predict the throughput and the response time of a replicated database using measurements of the workload on a standalone database. These models allow workload scalability to be estimated before the replicated system ...
2009Deferred-update database replication
This thesis is about the design of high-performance fault-tolerant computer systems. More specifically, it focuses on how to develop database systems that behave correctly and with good performance even in the event of failures. Both performance and depend ...
