An improvement in the infrastructure of the CNA laboratory directly leads to an improvement in the quality of education received in the laboratory. This thesis work described the creation of an alternative arrangement using Linux Ubuntu as a supplementary option in the studying of networking subjects in the CNA laboratory of the university. Linux Ubuntu is a free software available to download and with some adjustments and modifications it can be made to function just as properly as a Windows operating system in the experience of learning networking. The process of creating and deploying a customised Ubuntu image deployed via the Virtual Machine, was discussed in this thesis work. Linux is a UNIX-like software, the knowledge of which is valuable to students as they study to become professionals. An introduction to several applications such as Minicom, Wireshark, and Nmap was also discussed in this thesis. A simple laboratory experiment was designed to test the performance and functioning of the newly created system. Expertise in more than one operating system expands the horizon of future students of the UAS, an opportunity older students did not have, and capacitates them to become proficient engineers.

  • Architecture for Enabling Edge Inference Via Model Transfer from Cloud Domain in a Kubernetes Environment
    future internet Article Architecture for Enabling Edge Inference via Model Transfer from Cloud Domain in a Kubernetes Environment Pekka Pääkkönen *, Daniel Pakkala, Jussi Kiljander and Roope Sarala VTT Technical Research Centre of Finland, 90571 Oulu, Finland; daniel.pakkala@vtt.fi (D.P.); jussi.kiljander@vtt.fi (J.K.); roope.sarala@vtt.fi (R.S.) * Correspondence: pekka.paakkonen@vtt.fi Abstract: The current approaches for energy consumption optimisation in buildings are mainly reactive or focus on scheduling of daily/weekly operation modes in heating. Machine Learning (ML)-based advanced control methods have been demonstrated to improve energy efficiency when compared to these traditional methods. However, placing of ML-based models close to the buildings is not straightforward. Firstly, edge-devices typically have lower capabilities in terms of processing power, memory, and storage, which may limit execution of ML-based inference at the edge. Secondly, associated building information should be kept private. Thirdly, network access may be limited for serving a large number of edge devices. The contribution of this paper is an architecture, which enables training of ML-based models for energy consumption prediction in private cloud domain, and transfer of the models to edge nodes for prediction in Kubernetes environment. Additionally, pre- dictors at the edge nodes can be automatically updated without interrupting operation. Performance results with sensor-based devices (Raspberry Pi 4 and Jetson Nano) indicated that a satisfactory prediction latency (~7–9 s) can be achieved within the research context. However, model switching led to an increase in prediction latency (~9–13 s). Partial evaluation of a Reference Architecture for edge computing systems, which was used as a starting point for architecture design, may be considered as an additional contribution of the paper.

Providing superior fault tolerance, scalability, and migration, vir- tualization allows these companies to run several isolated operating systems simultaneously on the same physical server [13]. These isolated operating sys- tems, called virtual machines, require a virtual traffic guard to cooperate with one another. This guard known as the Credit2 scheduler along with the newest Xen hypervisor was recently developed to supersede the older schedulers. Since wasted CPU cycles can be costly, the Credit2 prototype must undergo sig- nificant performance validation before being released into production. Fur- thermore, leading commercial virtualization products, including VMWare and Microsoft Hyper-V frequently adopt Xen's proven technologies.

    Cyber-Physical Application Monitoring across Multiple Clouds ∗ Ayman Noora,b, Karan Mitrac, Ellis Solaimana, Arthur Souzad, Devki Nandan Jhaa, Umit Demirbagaa,e, Prem Prakash Jayaramanf, Nelio Cachod, Rajiv Ranjana aNewcastle University, Newcastle upon Tyne, UK bTaibah University, Madinah, Saudi Arabia cLule˚aUniversity of Technology, Skellefte˚a,Sweden dFederal University of Rio Grande do Norte, Natal, Brazil eBartin University, Bartin, Turkey fSwinburne University of Technology, Melbourne, Australia Abstract Cyber-physical systems (CPS) integrate cyber-infrastructure comprising com- puters and networks with physical processes. The cyber components monitor, control, and coordinate the physical processes typically via actuators. As CPS are characterized by reliability, availability, and performance, they are expected to have a tremendous impact not only on industrial systems but also in our daily lives. We have started to witness the emergence of cloud-based CPS. However, cloud systems are prone to stochastic conditions that may lead to quality of service degradation. In this paper, we propose M2CPA - a novel framework for multi-virtualization, and multi-cloud monitoring in cloud-based cyber-physical systems. M2CPA monitors the performance of application components running inside multiple virtualization platforms deployed on multiple clouds. M2CPA is validated through extensive experimental analysis using a real testbed compris- ing multiple public clouds and multi-virtualization technologies. Keywords: Cyber-physical system, Monitoring, Linear Road benchmark, QoS, Virtualization, Cloud Computing ∗ Preprint submitted to Computers and Electrical Engineering June 17, 2019 1. Introduction CPS is an interdisciplinary approach for combining communication devices, computation, and actuation for performing time-constrained actions in a predic- tive and adaptive manner [1, 2]. This is done using a feedback loop within the physical system, which enables the embedded and network systems to monitor and control the physical processes.

A cloud that emulates a physical server and is used by cloud server, which has sufficient resources all the time for its providers to share the same physical server with multiple clients as resource pools, efficiently and dynamically allocates cloud consumers by providing cloud consumers with or deallocates these resources, is considered good for its individual virtual server instances.
