, que la méta-programmation pouvait être un substrat possible pour la conception de langages d'aspects [3, 14], offrant ainsi de nouvelles propriétés comme le tissage dynamique dans AspectJ

. Puis, R. Le, and . Arcad, INRIA Rhône-Alpes) ? je me suis concentré sur le concept d'adaptation dynamique dans les architectures logicielles à base de composants. ARCAD a participé à l'émergence du modèle de composants Fractal (fractal.ow2.org), à la définition d'un patron d'auto-administration pour logiciel à base de composants avec le framework Safran [37], à la réalisation d'un intergiciel pour le monitoring (WidCAT [60]) mais également à la proposition d'un aspect d'adaptation pour la reconfiguration dynamique de composants Fractal, p.47, 2000.

R. Avec-le-projet and . Selfware, INRIA Rhône-Alpes) et encore T. Coupaye ? j'ai abordé un nouveau domaine qui était déjà un domaine cible mais implicite de mes précédents travaux : celui de l'autonomic computing. Mon idée était d'utiliser les approches langages dédiés (au sens Domain Specific Language) pour développer des langages sur mesure pour l'administration autonomique de systèmes répartis. L'intérêt du langage dédié est d'être spécifiquement conçu pour un domaine d'application particulier, celui de la reconfiguration dynamique dans notre cas. J'ai notamment contribué à la définition du langage de reconfiguration FScript [11, 59] pour le modèle de composants Fractal ; j'ai participé à l'intégration d'un moniteur transactionnel dans l'interpréteur FScript pour rendre les reconfigurations fiables, en parallèle avec mes partenaires de France Telecom R&D (N. Rivierre), intéressé par la gestion de la qualité de service (QoS) dans les orchestrations de Web services, p.58, 2005.

, INRIA pour prendre un peu de recul sur mes travaux de recherche Je réalise alors que j'ai focalisé une grande partie de mes travaux sur le Comment réaliser la reconfiguration dynamique mais presque pas sur le Pourquoi ? Même si certaines évaluations ont permis de (i) modifier les mécanismes de distribution à l'exécution (OpenCorba [39]) ; (ii) redimensionner un composant cache serveur à l'exécution et modifier la politique d'adaptation elle-même (Safran [37]) ; (ii) réaliser une auto-réparation d'un serveur Java EE [31] ; etc. je me sentais modestement motivé par ces expérimentations, Entre, 2008.

A. Partir-de-de-mon-collègue and J. Menaud, et je me suis orienté vers la thématique du Green computing dans le but d'optimiser l'empreinte énergétique des centres données qui accompagnent l'essor spectaculaire du Cloud computing [10]. L'idée phare est que le logiciel hébergé par un centre de données doit lui-même participer à la réduction de la consommation énergétique. D'où des problématiques d'optimisation multi-niveaux, multi-critères, de coordination de boucles autonomiques entre l'application et l'infrastructure virtuelle l'hébergeant [28]. La reconfiguration dynamique d'architectures Cloud multi-niveaux sera dirigée par des compromis qualité service, QoS)/empreinte énergétique (un composant gourmand en énergie rendant en général un service de meilleure qualité), 2010.

, C'est dans le cadre du projet ANR MyCloud (2010-2013) --et ses partenaires, en particulier Pierre Sens (LIP6) et Sara Bouchenak (INRIA Rhône-Alpes) --que nous avons abordé cette problématique et défini le langage CSLA, prenant finement en compte les caractéristiques du Cloud. Pour conclure, la gestion autonomique de l'élasticité multi-couche des applications dans le Cloud pour une utilisation efficiente des ressources devient ainsi un axe majeur de ma recherche ces dernières années, pp.8-08, 2018.
