The power of cloud orchestration


Cloud systems have been proven to be very useful to create complex digital services by deploying and connecting the required services in the cloud according to predefined descriptors. Meanwhile the creation of such descriptors requires deep cloud expertise, their usage requires only minimal cloud knowledge so even end-users with little cloud experience can apply them. Hence 1st generation cloud orchestrators (Terraform, Juju, Heat, Occopus, etc.) assisted the creation of such complex systems by significantly simplifying the deployment and configuration process of the component services. Beyond that they enabled the creation of reference architectures that play a particularly important role in Big data and AI applications. Another typical type of complex services are the data processing pipelines implemented as data workflows. In the first part of the talk we take a journey in the world of reference architectures and data pipelines and show how cloud orchestrators can help everyday work of system engineers and advance users to create such services in even heterogeneous, hybrid cloud systems.

Beyond the initial deployment of virtual machines and containers, second generation cloud orchestrators enable the dynamic scaling (up and down) of created complex digital services that makes these services much more efficient and economic in terms of always applying the optimal number of virtual machines and containers required by predefined conditions of running these services. Such a second-generation cloud orchestrator, called MiCADO was developed in the EU project COLA (Cloud Orchestration at the Level of Applications) and its power was demonstrated in several commercial application areas. One of them is evacuation modelling that was developed by Saker Solutions Ltd. and extended with the use of MiCADO. In the second part of the talk the concept and architecture of MiCADO will be explained and its usage in evacuation modelling will be described. Finally, some further plans of using and further extending MiCADO in the framework of the newly started EU project DigitBrain will be presented.

Interpretability in Data Analytics with Information Granules


One of the ongoing timely quests in data analytics is about interpretability of results. The problem is multifaceted as it engages various ways of characterization of the findings. We demonstrate that interpretability comes hand in hand with several key features including a level of abstraction of the findings, their stability and efficient ways of accommodation of domain knowledge so that it could be used as a sound guiding vehicle of user-centric knowledge discovery. We offer a formal formulation of the problem, propose some performance indexes and show interrelationships among the features identified above. We advocate that information granules supported by Granular Computing deliver a comprehensive conceptual and algorithmic processing environment. As clustering has been one among central conceptual pursuits of data analytics, we cast a general discussion with a close association with clusters and their interpretation. The general scheme composed of a series of phases: data¡ªclusters¡ªinformation granules-linguistic summarization is discussed vis-¨¤-vis successive levels of abstraction arising in the consecutive steps. We move beyond data-focused clustering mechanisms by bringing mechanisms of knowledge-oriented clustering where data intensive clustering is seamlessly combined with crucial pieces of domain knowledge. A class of reference-driven clustering algorithms is developed in which key results are expressed and quantified in terms of semantically sound and user -supplied landmarks.

Software Engineering Framework for IoT-Fog-Edge-CloudComputing (SEF-IFEC 2020)


IoT, Fog, Edge, and Cloud (IFEC) paradigm have emerged to address the need for more efficient integration of large scale real-time data streaming applications with widespread growth in IoT devices with 5G connected devices seamlessly. Besides, IFEC systems also needed to efficient control of trust, security & privacy (TSP) in the current pandemic of COVID-19 with multitude of devices and people connected with apps for predicting people to people. In addition, in recent years, we experienced lack of security concerns with smart home IoT applications such as home security cameras, etc. (Varghese & Hayajneh, 2018), (Hu, Yang, Lin, & Wang, 2020), & (Yassein, Hmeidi, Shatnawi, Mardini, & Khamayseh, 2019). Therefore, this talkproposes a systematic software engineering framework for IFEC applications which allow us to manage, maintain, and reuse on-the-fly. The tech analyst company IDC predicts there will be 50 billion connected IoT devices by 2025 (IDC 2019). Therefore, IFEC applications will generate and consume trillions of data volume and complex data traffic. Hence, this talk proposes a comprehensive requirements engineering framework for IFEC applications which can also be specified using BPMN modelling and simulation to verify and validate IFEC requirements with smart contracts using blockchain technology to Build Trust, Security, and Privacy In (BTSPI). Our initial design of IFEC architecture design and the simulation results fora large scale data streaming application shows the complexity and resource constraints needed before design and implementation which can save cost and improve process and quality of the IFEC applications.
