This article addresses the problem of self-tuning the data placement in replicated key-value
stores. The goal is to automatically optimize replica placement in a way that leverages …

Cloud Computing researches involve a tremendous amount of entities such as users,
applications, and virtual machines. Due to the limited access and often variable availability …

Data placement refers to the problem of deciding how to assign data items to nodes in a
distributed system to optimize one or several of a number of performance criteria such as …

The highly dynamic and heterogeneous environment that characterizes the edge of the
Cloud/Edge Continuum calls for new intelligent methods for tackling the needs of such a …

ZooKeeper atomic broadcast (Zab) is at the core of ZooKeeper system, enforcing a total
order on service requests that seek to modify the replicated service state. Since it is a leader …

It has been traditionally viewed that as the scale of a supercomputer increases, its energy
efficiency decreases due to performance that scales sub-linearly and power consumption …

Many different mechanisms have been developed to implement Distributed Transactional
Memory (DTM). Unfortunately, there is no “one-size-fits-all” design that offers the desirable …

Operating at the core of the highly-available ZooKeeper system is the ZooKeeper atomic
broadcast (Zab) for imposing a total order on service requests that seek to modify the …

Atomic Multicasts are central to the management of replicated data in distributed systems.
Previous work has proven the effectiveness of utilising atomic multicasts, opposed to the …

Large scale cloud applications are difficult to program due to the need to access data in a
consistent manner. To lift this burden from programmers, Deferred Update Replication …
