DESCRIPTION
Offrant un moyen simple de répartir des composants dans différentes machines virtuelles Java et d'assurer leur re-démarrage en cas d'erreur, la plateforme PSEM2M a rempli une bonne partie de ses objectifs. Les prochaines itérations de son développement ajouteront la capacité de la plateforme à réagir face à des indisponibilités ou des crashs chroniques ou critiques de services, ainsi que la gestion d'isolats hétérogènes (Python, ...).
