- Real-time data analytics for Non-Functional Requirements satisfactionPublication . Sousa, Rita Rocha de; Nogueira, Luís Miguel PinhoSmart systems, more than ever, demands processing a massive amount of data generated by heterogeneous and distributed data sources. This dissertation presents the contribution made to a software architecture that processes big-data analytics from the edge to the cloud. The software architecture integrates both responsive data-in-motion (edge computing) and latent data-at-rest analytics (cloud computing) into a single solution, satisfying extremescale analytics performance requirements. This dissertation focused on fulfilling the nonfunctional properties inherited from smart systems, such as real-time and energy-efficiency, to ensure the performance of the software architecture first referred. The Non-Functional Requirements (NRF) Tool manages computing resources and detects Quality of Service (QoS) violations. The Global Resource Manager (GRM) helps the scheduler/orchestrator redeploy the applications through the NFR Tools’ feedback. In addition, it can act reactively or proactively (recurring to Machine Learning techniques) to improve the system’s health.
