A Framework for Constraint-Based Deployment and Autonomic Management of Distributed Applications (Extended Abstract)

TL;DR

This paper presents a framework that uses declarative constraints and a constraint solver to automate the deployment and autonomic management of distributed applications, enabling dynamic reconfiguration to meet evolving goals.

Contribution

It introduces a novel framework combining constraint-based deployment with autonomic management for distributed applications, allowing automatic reconfiguration based on goal satisfaction.

Findings

Automated deployment based on declarative constraints.

Dynamic reconfiguration to maintain deployment goals.

Integration of constraint solving with autonomic management.

Abstract

We propose a framework for the 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.
