Reconfigurable Applications Using GCMScript

Abstract

Nowadays, applications are commonly deployed in distributed environments using multiple computational resources from elastic cloud infrastructures. Environmental conditions, however, may vary through different providers or even at runtime and the applications must be able to quickly adapt to new conditions. Component based applications plus autonomic computing appear as flexible solutions to make applications reconfigurable and more adaptable. Programming of autonomic behavior, however, is not an easy task. In this work we use a component based framework to build reconfigurable and distributed applications, plus a scripting language to facilitate the programming of autonomic behavior. We show the effectivity of our approach using a distributed master-worker application that is able to self-adjust its load.

Component-based Distributed Software Reconfiguration:A Verification-oriented Survey

“…Reconfiguring and adapting a large system in a hierarchical way facilitates its compositional management and the scaling up of adaptation procedures [75]. Flat models are generally more flexible but sometimes harder to manage: because many components are at the same level, composing, maintaining or providing reconfiguration capabilities for large systems is often more difficult.…”
