a federated multi-cloud paas infrasctructure
DESCRIPTION
Cloud platforms are increasingly being used for hosting a broad diversity of services from traditional e-commerce applications to interactive web-based IDEs. However, we observe that the proliferation of offers by cloud providers raises several challenges. Developers will not only have to deploy applications for a speci?c cloud, but will also have to consider migrating services from one cloud to another, and to manage distributed applications spanning multiple clouds. In this paper, we present our federated multi-cloud PaaS infrastructure for addressing these challenges. This infrastructure is based on three foundations: i) an open ser- vice model used to design and implement both our multi- cloud PaaS and the SaaS applications running on top of it, ii) a con?gurable architecture of the federated PaaS, and iii) some infrastructure services for managing both our multi- cloud PaaS and the SaaS applications. We then show how this multi-cloud PaaS can be deployed on top of thirteen ex- isting IaaS/PaaS. We ?nally report on three distributed SaaS applications developed with and deployed on our federated multi-cloud PaaS infrastructure.TRANSCRIPT
