Abstract-The 4CaaSt project aims at developing a PaaS framework that enables flexible definition, marketing, deployment and management of Cloud-based services and applications. The major innovations proposed by 4CaaSt are the blueprint and its lifecycle management, a one stop shop for Cloud services and a PaaS level resource management featuring elasticity. 4CaaSt also provides a portfolio of ready to use Cloud native services and Cloud-aware immigrant technologies. The necessary tools to monitor the execution and manage the lifecycle of applications. Overall, the project will bring significant benefits to the European economy via a greatly simplified design and delivery model for services and service compositions thus contributing to the establishment of new and highly dynamic and innovative service ecosystems.

Network Management faces major challenges nowadays. Management applications have not kept the changing pace of networks and services and still rely on centralized approaches. Moreover, uncertainty is part of the reality. This paper presents a lightweight collaborative approach to network troubleshooting, based in multi agents and probabilistic techniques. The proposed architecture has been applied to three different network environments.
