Internal Self-protecting for Consistency and Stability in an Autonomic Manager

In this article we describe an approach for autonomic management of legacy software in distributed environments (cluster, grid or cloud). Our propositions have been implemented in a tool (TUNe) based on diagrams formalisms. We describe particularly the property of self-Protecting. The various mechanisms needed to maintain the consistency of the managed system, are described: autonomic creation or destruction, interruption or rollback. Finally experiments using this policy are made on the software DIET.
