Policy-based self-management of industrial service systems

Abstract

Service-orientation supports the construction of flexible and comprehensive industrial applications. The growing scale and complexity of the applications, however, demand for enhanced self-management functions providing efficient self-adaptation and repair mechanisms. We propose the approach of policy-controlled self-management which has been developed and successfully tested in the context of Web Service based control applications. We use hierarchically structured management policies where high-level policies serve as abstract definitions of management objectives and low-level policies represent concrete rules for resource monitoring und correcting interventions. The definition, analysis, refinement and deployment of the policies are supported by an interactive graphical modeling tool. Index Terms-model-based management, fault tolerant systems, web services

Conceptual Framework for a Comprehensive Service Management Middleware

“…The modules in CSMM are designed as Web services and have a more distributed architecture. Illner et al [5] present their work on policy governed automated management of embedded service systems using model-based approach. Our work uses policies only for the NM, and focuses on managing and executing consumer calls rather than managing Web service systems.…”

“…5.2 briefly describes the common supporting tool of the MBM approach, which was already existing in the beginning of the present work and was further developed both by other research groups on MBM (e.g. the SIRENA project [47,46]) and in the context of the present work. The tool firstly assists the modelling by means of a diagram editor, and it then executes the policy refinement process.…”
