The novelty of 2014 consists in the development of the soCloud platform for distributed multi-cloud systems. This platform has been defined in the context of the PhD thesis of Fawaz Paraiso [15] that was defended in June 2014. soCloud is built on top of our existing FraSCAti platform. soCloud enables to deploy, execute and manage an application that spans on several different cloud systems.

FraSCAti is a service-oriented component-based middleware platform implementing OASIS Service Component Architecture (SCA) specifications. The main originality of FraSCAti is to bring Fractal -based reflectivity to SCA, i.e., any FraSCAti software component is equipped with both the SOA capabilities brought by SCA and the reflective capabilities (i.e., introspection and reconfiguration) brought by Fractal . Various micro-benchmarks have shown that FraSCAti reflectivity is achieved without hindering its performance relative to the de facto reference SCA implementation, i.e., Apache Tuscany. Non-functional concerns (logging, transaction, security, etc.), so-called intents in SCA terms, are also programmed as FraSCAti components and are (un)woven on business components dynamically at runtime, this is based on aspect-oriented concepts defined in FAC  [110] . FraSCAti supports various implementation technologies (SCA Composite, Java, WS-BPEL, Spring Framework, OSGi, Fractal ADL, native C library, Apache Velocity templates, and seven scripting languages as BeanShell, FScript, Groovy, JavaScript, JRuby, Jython, XQuery) for programming services or integrating legacy code, various binding protocols (SOAP, REST, JSON-RPC, UPnP, HTTP servlets, Java RMI, JMS, JGroups) and interface definition languages (WSDL, Java, WADL) for interoperating with existing services. FraSCAti provides management tools like standalone, Web-based, and JMX-based graphical consoles and a dedicated scripting language for reconfiguring SCA applications. The whole FraSCAti platform is itself built as a set of reflective SCA components.
