Analysing FIWARE's platform - Potential improvements

The digitalization of the world proceeds continually. As part of this, we are facing a smart digital future where everything is connected and linked while we are transforming big data into knowledge. The FIWARE platform, which is the result of a series of EU funded projects, supports this transformation. Developers, integrators and end users are able to rapidly create new applications, by using components provided by this platform. We have analyzed central building blocks of the FIWARE platform from different aspects and - based on experiments and code reviews - like the need for a multi-level role-based security or a caching mechanism when it comes to querying data. Within this paper we also provide further recommendations for the current code base that can help to improve those FIWARE components under investigation. In addition to that we also suggest how to simplify a typical setup by extending FIWARE's core component using a Websocket-Port.
