摘要

We propose a framework for deployment and subsequent autonomic management ofcomponent-based distributed applications. An initial deployment goal isspecified using a declarative constraint language, expressing constraints overaspects such as component-host mappings and component interconnection topology.A constraint solver is used to find a configuration that satisfies the goal,and the configuration is deployed automatically. The deployed application isinstrumented to allow subsequent autonomic management. If, during execution,the manager detects that the original goal is no longer being met, thesatisfy/deploy process can be repeated automatically in order to generate arevised deployment that does meet the goal.
