Distributed Event Correlation and Self-Managed Systems

The systems that currently provide Internet users with sophisticated e-business services struggle to offer high availability guarantees while being managed as regu-lar systems, because management architectures rely on the manager-agent paradigm and domain-based distribution. In this paper, we argue that e-business information systems should instead be structured as self-managed systems: they need to detect problems by themselves, work out the cause of each problem, and take corrective actions independently of any external entity. They should not depend on external managers for their efficiency and robustness. To achieve this, we propose an organizational model that allows manage-ment architectures to take into account the specific requirements of self-managed systems, and investigate how to distribute event correlation in the presence of self-managed systems
