This deliverable presents the final version of the overall MUSA framework architecture, including the intended usage scenarios, along with the derived final project requirements that have guided the MUSA research and implementation work. The deliverable has followed an iterative approach with the collaboration of all project participants and it serves as a common project reference across all the technical work packages. The deliverable contains also a glossary that defines the main concepts handled in the project. The final version is fully aligned with the more detailed descriptions about design and implementation of the components of the MUSA framework (technical deliverables in WP2, WP3 and WP4). This deliverable also describes the final version of the guide to security management in multi-cloud applications lifecycle provided by MUSA. It describes the MUSA framework’s impact on integrated and holistic management of application security across the whole life cycle.
