The Department of Computer Science at the University of Cyprus cordially invites you to the Colloquium entitled:
On the Elasticity of NoSQL Databases over Cloud Management Platforms
Speaker: Dr. Dimitrios Tsoumakos
NoSQL databases focus on analytical processing of large scale datasets, offering increased scalability over commodity hardware. One of their strongest features is elasticity, which allows for fairly portioned premiums and high-quality performance. Yet, the process of adaptive expansion and contraction of resources usually involves a lot of manual effort during cluster configuration. In this work, we perform a thorough study of the elasticity feature on some popular NoSQL databases over an open-source cloud computing platform. We also present a prototype implementation of a decision making system that enables automatic elastic operations of any NoSQL engine based on administrator or application-specified constraints.
Dr. Tsoumakos is an Assistant Professor in the Department of Informatics of the Ionian University. He is also a senior researcher at the Computing Systems Laboratory of the National Technical University of Athens (NTUA). He received his Diploma in Electrical and Computer Engineering from NTUA in 1999 and joined the graduate program in Computer Sciences at the University of Maryland in 2000, where he received his M.Sc. (2002) and Ph.D. (2006). His research interests lie in the area of distributed data management, particularly in designing and implementing adaptive, scalable and bandwidth-efficient schemes for data storage, retrieval and dissemination. Applications over Cloud platforms, Peer-to-Peer and Grid systems are considered. He has also been involved in Database research, especially in designing distributed indexing schemes for sharded databases. His most recent projects relate to automatic elasticity provisioning for NoSQL engines and scalable RDF query processing using NoSQL and MapReduce.
