Things take time…

My current current research interests are related to large-scale data management for distributed infrastructures. I share these interests with Gabriel Antoniu, co-founder of the KerData Team. I am specially interested in the semantic specification of the various management operations.

Relevant topics of interest:

• Parallel and distributed computing
• Grid computing, P2P systems and cloud computing
• Distributed data storage and sharing
• BLOB-based storage
• Distributed file systems

Recently, within the KerData Team, we started to design, implement and experimentally validate of a generic data-sharing platform called BlobSeer. It is designed to serve as a basis for storing and sharing massive data accessed at a fine grain under heavy concurrency, while supporting versioning and decentralized metadata management.

Less recently, I have worked on the concept of Grid Data-Sharing Service, defined using a hybrid approach based on Distributed Shared Memory and Peer-to-Peer techniques. This approach has been illustrated by the JuxMem prototype.

The Grid Data-Sharing Service approach has been developed in the context of the GDS project of the French ACI Masses de données (2003-2006) and has been enhanced and validated within the LEGO and RESPIRE ANR projects (2006-2009).

Data management, cloud computing, service, PaaS, BlobSeer, Nimbus

The emerging cloud computing model is currently gaining a lot of interest from both industry and academia in the area of large-scale distributed computing. Cloud computing provides a new paradigm for managing computing resources: instead of buying and managing hardware, users rent virtual machines and storage space. Various cloud software stacks have been proposed by leading industry companies, like Google, Amazon or Yahoo.

In this new context, one of the most critical challenges relates to data management. The KerData research team of IRISA, Rennes, has recently been created with the goal of exploring ways to address the main challenges raised by the emergence of cloud environments with respect to data storage and access. The team is currently designing and implementing BlobSeer, a data-sharing platform which aims at providing support for storing massive data accessed at fine-grain under heavy concurrency, while supporting versioning and decentralized metadata management. The goal of the work proposed for this internshipis to explore how the BlobSeer platform could be used in cooperation with the Nimbus cloud computing environment from Argonne National Lab. BlobSeer should directly be available as a distributed file system to a group of clients (e.g. within a virtual organization) collaborating in an application running on a PaaS (Platform-as-a-Service).

The work will be carried in collaboration with the Nimbus team from Argonne National Lab and includes a design, implementation and evaluation phase. The implementation will rely on the BlobSeer data-sharing platform and on Nimbus software infrastructure. The validation phase will include intensive, large-scale experiments on the Grid'5000 grid testbed. The intern will work in close collaboration with Alexandra Carpen-Amarie, Ph.D. student in the KerData team.
