As Cloud Computing provides agile and scalable IT infrastructure, QoS-assured services and customizable computing environment, it increases the call for agile and dynamic deployment and governance environments over mul-ti-cloud infrastructure. By now, governance and Non Functional Properties (such as security, QoS…) are managed in a static way, limiting the global bene-fits of deploying service-based information system over multi-cloud environments. To overcome this limit, we propose a contextualised policy generation process to allow both an agile management NFP in a multi-cloud context and a secured deployment of the service-based information system. The last step of this Model Driven Policy Engineering approach uses policies as Mod-el@runtime to select, compose, deploy and orchestrate NFP management func-tions depending on the exact execution context. Moreover, a dynamic govern-ance loop including autonomic KPI management is used to control continuously the governance results.
