Gestion transactionnelle de la reprise sur erreurs dans le deploiement

TL;DR

This paper introduces a transactional approach to handle errors during automated software deployment, ensuring site consistency and preserving progress amidst exceptions.

Contribution

It proposes a novel transactional method for error recovery in deployment processes, validated through experimentation in an academic deployment system.

Findings

The approach maintains site consistency during deployment errors.

It preserves completed work to avoid redoing tasks after failures.

Experimental results demonstrate effectiveness in real deployment scenarios.

Abstract

With the development of the networks and the Internet, the problems of automated deployment on broad scale became increasingly crucial. Software deployment is a complex process covering several activities going from the configuration to the retirement of a software product. During the execution of a deployment process, exceptions can be met which put the site in an incoherent state. To solve them, we propose an approach based on transactional concepts which describes the actions to be undertaken when an exceptional situation is met during the deployment process. The approach guaranties the respect of the site's consistency by preserving part of the work already carried out by the process. This article presents our approach and an experimentation made in an academic deployment system.
