autonomic management policy specification in tune
Distributed software environments are increasingly complex and difficult to manage, as they integrate various legacy software with specific management interfaces. Moreover, the fact that management tasks are performed by humans leads to many configuration errors and low reactivity. This is particularly true in medium or large-scale distributed infrastructures. To address this issue, we explore the design and implementation of an autonomic management system. The main principle is to wrap legacy software pieces in components in order to administrate a software infrastructure as a component architecture. However, we observed that the interfaces of a component model are too low-level and difficult to use. Therefore, we introduced higher-level formalisms for the specification of deployment and management policies. This paper overviews these specification facilities that are provided in the Tune autonomic management system.
