A Model-Based Approach for the Integration of Configuration Fragments

A complex system configuration often consists of different fragments developed separately and integrated later to relate them in a consistent manner. The integration process follows certain rules, which relate the elements from the different fragments and ensure certain properties for the complete system configuration. In this paper we propose a model driven approach based on the concept of model weaving. It integrates the configuration fragments into a system configuration while targeting some specific system properties. Our approach is discussed and illustrated within the context of the Service Availability Forum (SA Forum) middleware, where we integrate the Availability Management Framework (AMF) configuration of an application that provides services to the users with the Platform Management Service (PLM) configuration of the platform, which represents the lower layer entities such as the operating systems, virtual machines, hypervisors and hardware elements.
