The distribution of computing services for buildings design and optimal management: cloud computing based on software component standard

International audienceThe optimal building management requires developed models to predict building's systems behaviour. We propose to achieve this goal, by making available on the web, remote computation services for the composition, simulation and optimization of buildings components. A paradigm shift is necessary in order to fulfil this goal. The well suited paradigm is software components, associated with web-services technologies. We show that models can be embedded in software components and after that, made available on the web without any special effort of the user. We illustrate the use of a web-service calculation by the realization of a remote optimization without ever holding the model

Roboconf: a Hybrid Cloud Orchestrator to Deploy Complex Applications

International audienceThis paper presents Roboconf, an open-source distributed application orchestration framework for multi-cloud platforms, designed to solve challenges of current Autonomic Computing Systems in the era of Cloud computing. It provides a Domain Specific Language (DSL) which allows to describe applications and their execution environments (cloud platforms) in a hierarchical way in order to provide a fine-grained management. Roboconf implements an asynchronous and parallel deployment protocol which accelerates and makes resilient the deployment process. Intensive experiments with different type of applications over different cloud models (e.g. private, hybrid, and multi-cloud) validate the genericity of Roboconf. These experiments also demonstrate its efficiency comparing to existing frameworks such as RightScale, Scalr, and Cloudify

An Adaptable Framework to Deploy Complex Applications onto Multi-cloud Platforms

International audienceCloud computing is nowadays a popular technology for hosting IT services. However, deploying and reconfiguring complex applications involving multiple software components, which are distributed on many virtual machines running on single or multi-cloud platforms, is error-prone and time-consuming for human administrators. Existing deployment frameworks are most of the time either dedicated to a unique type of application (e.g. JEE applications) or address a single cloud platform (e.g. Amazon EC2). This paper presents a novel distributed application management framework for multi-cloud platforms. It provides a Domain Specific Language (DSL) which allows to describe applications and their execution environments (cloud platforms) in a hierarchical way in order to provide a fine-grained management. This framework implements an asynchronous and parallel deployment protocol which accelerates and make resilient the deployment process. A prototype has been developed to serve conducting intensive experiments with different type of applications (e.g. OSGi application and ubiquitous big data analytics for IoT) over disparate cloud models (e.g. private, hybrid, and multi-cloud), which validate the genericity of the framework. These experiments also demonstrate its efficiency comparing to existing frameworks such as Cloudify

Distribution des services de calcul pour la conception et la gestion optimale des bâtiments: perspectives des approches composants déployés via le " cloud computing "

International audienceLa gestion optimale des bâtiment nécessite des modèles afin d'anticiper, sur un horizon plus ou moins lointain, le comportement du système bâtiment. Nous proposons, pour atteindre cet objectif, de mettre à disposition, sur le web, des services de calcul permettant la composition, la simulation et l'optimisation à distance des équipements constituant chaque bâtiment. Un changement de paradigme est alors nécessaire, afin d'outiller au mieux cette nouvelle voie. Le paradigme adapté à ces enjeux est celui des composants logiciels, associé aux technologies des web-services. Nous montrons que les modèles peuvent être embarqués dans des composants logiciels et mis à disposition sur le web sans effort particulier du modélisateur. Nous illustrons l'utilisation d'un web-service de calcul par la réalisation d'une optimisation à distance sans jamais disposer du modèle

Cloud computing services for the design and optimal management of buildings

International audienceThe optimal building management models require predicting the behaviour of building systems. To achieve this goal, we propose to make available on the web remote computing services for the composition, simulation and optimization of equipments. A paradigm shift is necessary in order to fulfil this goal. We show in this study that models can be embedded in software components and made available on the web without any special programming skills. A proof-of-concept prototype is provided as demonstration, and a remote optimization is done without ever holding the model as a possible use of such a concept
