Un meta-modele pour l'automatisation du deploiement d'applications logicielles

Le deploiement est maintenant considere comme une activite a part entiere du cycle de vie du logiciel. Les grandes entreprises souhaitent pouvoir automatiser cette etape tout en prenant en compte les caracteristiques de chaque machine cible. Pour repondre a ces besoins, nous avons defini un environnement de deploiement : ORYA (Open enviRonment to deploY Applications). Cet environnement utilise un meta-modele de deploiement, decrit dans ce papier. Notre approche utilise aussi les technologies des federations et des procedes, fournissant un environnement flexible et extensible pour l'utilisateur. ----- The deployment is now a full activity of the software lifecycle. Large enterprises want to automate this step, taking into account characteristics of each target machine. To satisfy these needs, we have defined an environment for the deployment phase: ORYA (Open enviRonment to deploY Applications). This environment uses a deployment metamodel, described in this paper. Our approach is based also on federation and process federations, providing a flexible and extensible environment to the use

Multi-Level Composition for Software Federations

Reusability is the holly grail of software engineers. But reusability requires powerful composition mechanisms since the pieces to compose have no reason to match perfectly. Unfortunately, the composition mechanisms available today, mostly method call and component assembly are rather primitive. This paper shows what is the current state of the art in software composition, showing that there is little composition flexibility at code level, even using workflow approaches
