The DIRAC interware project provides a framework for building ready to use distributed computing systems. It has been proven to be a useful tool for large international scientific collaborations integrating in a single system, their computing activities and distributed computing resources: Grids, Clouds and HTC clusters. In the case of Cloud resources, DIRAC is currently integrated with Amazon EC2, OpenNebula, OpenStack and CloudStack. Some Monte Carlo (MC)simulation campaign were realized at the large scale project Belle II, providing over 10.000 thousand CPU days from Amazon. Until this use case in Fedcloud-tf, all cases have made used of a single cloud at a time. The work integrates the resources provided by the multiple private clouds of the EGI Federated Cloud and additional WLCG resources, providing high-level scientific services on top of them by using the DIRAC framework. New design has been adopted by a federated hybrid cloud architecture (Rafhyc). Initial integration and scaling tests demonstrates the architecture is valid to manage federated hybrid cloud IaaS to provide eScience SaaS. The solution has been adopted by LHCb DIRAC for the LHCb computing on federated clouds, using end-points just like another computing resource.
Use Case 1: Running LHCb simulations of Monte Carlo jobs using IaaS federated manner, for integration and scaling tests.(Finished)
Use Case 2: Integrate the DIRAC extensions: LHCb-DIRAC and VMDIRAC (federated cloud) to reach a production level for the LHCb computing
