soCloud : une plateforme multi-nuages distribuée pour la conception, le déploiement et l'exécution d'applications distribuées à large échelle

摘要

Multi-cloud computing has established itself as a paradigm of choice for creating very large scale world wide distributed applications. Multi-cloud computing is the usage of multiple, independent cloud environments, which assumed no priori agreement between cloud providers or third party. However, these applications, designed for multi-cloud environments, have to face real challenges in term of design, architecture, and technology. The possibility of using multi-cloud faces the heterogeneity and complexity of cloud solutions. Thus, multi-cloud computing has to face several challenges such as portability, provisioning, elasticity, and high availability we have identified in this thesis. In this thesis, we propose soCloud both a model and a platform that tackle these four challenges. This model is based on the OASIS Service Component Architecture (SCA) standard to design distributed large scale applications for multi-cloud environments. A new language is proposed to effectively express the elasticity of multi-cloud applications through abstraction. The multi-cloud platform is designed to deploy and manage distributed applications across multi-clouds. The soCloud model is illustrated on three distributed applications deployed in multi- cloud environments. The soCloud platform has been implemented, deployed and experimented on top of ten existing cloud providers : Windows Azure, DELL KACE, Amazon EC2, CloudBees, OpenShift, dotCloud, Jelastic, Heroku, Appfog, and an Eucalyptus private cloud. These experiments are used to validate the novelty of the contributed solutions. With our contributions, we aim to provide a simple and effective way to design, deploy, run, and manage distributed applications for a multi-cloud environment by proposing a model and platform.
