分布式应用程序基于约束的部署和自主管理框架

A Framework for Constraint-Based Deployment and Autonomic Management of Distributed Applications

Alan Dearle, Graham Kirby, Andrew McCarthy

摘要:

我们提出了一个基于组件的分布式应用程序的部署和随后的自主管理框架。使用声明性约束语言指定初始部署目标,表达组件-主机映射和组件互连拓扑等方面的约束。约束求解器用于找到满足目标的配置,并且配置被自动部署。对部署的应用程序进行检测,以允许后续的自主管理。如果在执行期间,管理器检测到不再满足原始目标,则可以自动重复满足/部署过程,以便生成满足目标的修订部署。

英文摘要:

We propose a framework for deployment and subsequent autonomic management of component-based distributed applications. An initial deployment goal is specified using a declarative constraint language, expressing constraints over aspects 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 is instrumented to allow subsequent autonomic management. If, during execution, the manager detects that the original goal is no longer being met, the satisfy/deploy process can be repeated automatically in order to generate a revised deployment that does meet the goal.
