CloudDB: A Data Store for All Sizes in the Cloud
               Hakan Hacigumus, NEC Labs America

CloudDB project, which is underway at NEC Labs America, aims at
creating a comprehensive data management platform in the cloud. The
envisioned platform would provide data management capabilities as a
service to transparently and efficiently support diverse application
workloads with identifiable SLA guarantees and end-to-end system
management functions. The system will be able to employ heterogonous
underlying storage models to effectively meet applications' query and
scalability requirements. We propose the achievement of data
independence for all underlying specific storage models as the key
guiding principle for the system. If the system is able to achieve
data independence, the application logic is decoupled from the data
processing logic and allows applications to enjoy the benefits of
individual storage models, which are optimized for particular
purposes, without worrying about the specifics of data processing.
This talk will describe the vision, and our rationale for why such a
system is needed and desirable. We will also highlight some
significant challenges to the realization of such a system.
