Elaboration of a Future Architecture for Interoperable IT Systems at eu-LISAElaboration of a Future Architecture for Interoperable IT Systems at eu-LISAThis paper introduces the main goals, deliverables and conclusions of the feasibility study ‘Elaboration of a future architectural framework for interoperable IT systems at eu-LISA impact assessment and migration and integration plan’. The aims of the study were to identify and analyse the feasibility of various options for the architectural design and development of future systems by the European Union Agency for the Operational Management of Large-Scale IT Systems in the Area of Freedom, Security and Justice (eu-LISA), along with the interoperability components (as described in the interoperability regulations), and thus to assess the architectural possibilities for deploying the solutions and to outline perceived optimal architectural descriptions in the form of architectural description artefacts.83{2fd95b2e-c57c-48dd-8362-98741cbab0df}
