System and Method for Optimizing Data Storage in a Distributed Data Storage Environment

Karl Aberer, Nicolas Bonvin, Athanasios Papaioannou

A growing amount of data is produced daily resulting in a growing demand for storage solutions. While cloud storage providers offer a virtually infinite storage capacity, data owners seek geographical and provider diversity in data placement, in order to a ...

Linear Scalability of Distributed Applications

Nicolas Bonvin

The explosion of social applications such as Facebook, LinkedIn and Twitter, of electronic commerce with companies like Amazon.com and Ebay.com, and of Internet search has created the need for new technologies and appropriate systems to manage effectively ...

Scalia: An Adaptive Scheme for Efficient Multi-Cloud Storage

Karl Aberer, Nicolas Bonvin

A growing amount of data is produced daily resulting in a growing demand for storage solutions. While cloud storage providers offer a virtually infinite storage capacity, data owners seek geographical and provider diversity in data placement, in order to a ...

Autonomic SLA-driven Provisioning for Cloud Applications

Karl Aberer, Nicolas Bonvin

Significant achievements have been made for automated allocation of cloud resources. However, the performance of applications may be poor in peak load periods, unless their cloud resources are dynamically adjusted. Moreover, although cloud resources dedica ...

Cost-efficient and Differentiated Data Availability Guarantees in Data Clouds

Karl Aberer, Nicolas Bonvin

Failures of any type are common in current datacenters. As data scales up, its availability becomes more complex, while different availability levels per application or per data item may be required. In this paper, we propose a self- managed key-value stor ...

A self-organized, fault-tolerant and scalable replication scheme for cloud storage

Karl Aberer, Nicolas Bonvin

Failures of any type are common in current datacenters, partly due to the higher scales of the data stored. As data scales up, its availability becomes more complex, while different availability levels per application or per data item may be required. In t ...

An economic approach for scalable and highly-available distributed applications

Karl Aberer, Nicolas Bonvin

Service-oriented architecture (SOA) paradigm for orchestrating large-scale distributed applications offers significant cost savings by reusing existing services. However, the high irregularity of client requests and the distributed nature of the approach m ...

From Web Data to Entities and Back

Zoltán Miklós, Michele Catasta, Nicolas Bonvin, Julien Gaugaz, Ekaterini Ioannou

We present the Entity Name System (ENS), an enabling infrastructure, which can host descriptions of named entities and provide unique identifiers, on large-scale. In this way, it opens new perspectives to realize entity-oriented, rather than keyword-orient ...

Dynamic Cost-Efficient Replication in Data Clouds

Karl Aberer, Nicolas Bonvin

Hardware failures in current data centers are common partly due to the higher data scales supported. Data replication is the common approach for improving availability. However, mostly static replication approaches have been proposed, i.e. the number of re ...
