    • A method for providing change management in a distributed system is provided. The method includes compiling a policy for change management in the distributed system, the policy includes at least one policy rule based on an event-condition-action (ECA) framework with a pre-condition and a post-condition to an action in the policy rule, wherein the pre-condition is separate from a condition of the policy rule and indicates a prior condition in the distributed system that enables the action, and the post-condition indicates a subsequent condition in the distributed system that results from the action; receiving at least one event indicating a change in the distributed system; determining that the at least one received event triggers the at least one policy rule; generating a workflow to manage the change in the distributed system based on the at least one triggered policy rule; and initiating one or more actuators in the distributed system to dynamically configure or deploy components in the distributed system to execute the workflow.
    • 提供了一种在分布式系统中提供变更管理的方法。 该方法包括编制分布式系统中的变更管理策略,该策略包括至少一个基于事件条件动作(ECA)框架的策略规则,该策略规则具有策略中的动作的前提条件和后置条件 规则,其中所述前提条件与所述策略规则的条件分离并且指示所述分布式系统中的启用所述动作的先前条件,并且所述后置条件指示由所述动作导致的所述分布式系统中的后续条件; 接收指示分布式系统的变化的至少一个事件; 确定所述至少一个接收的事件触发所述至少一个策略规则; 生成工作流以基于所述至少一个触发的策略规则来管理所述分布式系统的变化; 以及启动所述分布式系统中的一个或多个致动器以动态地配置或部署所述分布式系统中的组件以执行所述工作流。
