Design of a Monitoring Solution based on ELASTIC STACK (Elasticsearch, Kibana, Beats, and Logstash) to support customers using ECMs (Entreprise Content Management): - detect and alert any downtime or degradation of the service - centralize all the monitoring information in a single interface - continuously audit the performance as seen by users - go back in time to analyze a particular or specific situation at any time - establish statistics and pertinent… Show more Design of a Monitoring Solution based on ELASTIC STACK (Elasticsearch, Kibana, Beats, and Logstash) to support customers using ECMs (Entreprise Content Management): - detect and alert any downtime or degradation of the service - centralize all the monitoring information in a single interface - continuously audit the performance as seen by users - go back in time to analyze a particular or specific situation at any time - establish statistics and pertinent dashboards Show less

(b) Extension of the OCARINA Back-End part and its Runtime POLYORB-HI/C to implement code generation rules from the BA.- Development of a simulated RTOS (real-time operating system), in the form of a C API allowing the creation and scheduling of threads. This is to simulate the system without altering the clock and the consistency of the thread activation. This API will be used in the POLYORB-HI-C middelware to replace Posix threads and subsequently allow execution with a simulated RTOS. Show less

- The increasing complexity and scale of critical real-time systems leads to a large number of possible architectures which poses a major challenge for designers when making design decisions. These architectures must meet the system non-functional constraints while balancing multiple conflicting performance criteria. We propose in this thesis, a design space exploration process that provides a set of feasible architectures answering at best to trade-offs between performance criteria. To do so… Show more - The increasing complexity and scale of critical real-time systems leads to a large number of possible architectures which poses a major challenge for designers when making design decisions. These architectures must meet the system non-functional constraints while balancing multiple conflicting performance criteria. We propose in this thesis, a design space exploration process that provides a set of feasible architectures answering at best to trade-offs between performance criteria. To do so, we formulate the problem using multi-objective optimization technique based on evolutionary algorithms. In order to formalize design alternatives explored during the process, a set of rules are defined allowing to compute parameters of the design entities. Furthermore, we address the scalability and the effectiveness of design exploration process by adapting it for implementation in parallel environments.- All the contributions of the thesis are implemented into a prototype which is integrated into the open source scheduling tool called CHEDDAR (http://beru.univ-brest.fr/svn/CHEDDAR/trunk/). Chapter 6 of the thesis manuscript describes the prototype that I implemented. Show less
