A Self-organizing Data Store for Large Scale Distributed Infrastructures

The introduction of Service Oriented Architectures enables the transition from integrated, centrally controlled systems to federated and dynamic configurable systems. Scalability and reliability are key requirements for such infrastructures. Due to the size and dynamic only decentralized and self-organizing systems are able to accomplish the previously mentioned requirements. In this paper we describe our approach to tackle the problem within the BRICKS project. Here we use a completely decentralized XML database to store several types of metadata. We will present the database architecture and the way it is used in the BRICKS architecture, exemplary for service discovery. Furthermore will we give an overview of current research activities and preliminary results.
