Convey’s hybrid-core technology provides a solution. The rapid growth of the Internet, and the emergence of hyperscale computing are placing new demands on the flow of web traffic. For example, companies like Amazon, Google, and Facebook have created hyperscale data centers to handle exponentially increasing traffic driven by social networking and on-line commerce. The problem of delivering content to consumers in a real-time manner is compounded by this explosive growth.

Mobile Edge Computing: Architecture, Use-cases, Applications Craig Pritchard, Yousef Beheshti, Mohammad Sepahi Abstract| By enormous growth in IoT and smart devices and the ad- vent of many new applications, Internet traffic volume has been grow- ing exponentially. Analyzing such flooding traffic requires enormous compute and bandwidth and raises privacy concerns. Edge platforms can become the tool to ease the burden by bringing resources to the proximity of data. Therefore, new architectures, which bring network functions and contents to the network edge, are proposed, i.e., mobile edge computing and caching. In this survey, we make an exhaustive review on the literature research efforts on mobile edge networks. We give an overview of mobile edge networks, including definition, archi- tecture, and application and use-cases . We then survey the issues related to computing, caching, and communication techniques at the network edge with the focus on applications and use cases of mobile edge networks.

  • Computer Demos—What Makes Them Tick?
    AALTO UNIVERSITY School of Science and Technology Faculty of Information and Natural Sciences Department of Media Technology Markku Reunanen Computer Demos—What Makes Them Tick? Licentiate Thesis Helsinki, April 23, 2010 Supervisor: Professor Tapio Takala AALTO UNIVERSITY ABSTRACT OF LICENTIATE THESIS School of Science and Technology Faculty of Information and Natural Sciences Department of Media Technology Author Date Markku Reunanen April 23, 2010 Pages 134 Title of thesis Computer Demos—What Makes Them Tick? Professorship Professorship code Contents Production T013Z Supervisor Professor Tapio Takala Instructor - This licentiate thesis deals with a worldwide community of hobbyists called the demoscene. The activities of the community in question revolve around real-time multimedia demonstrations known as demos. The historical frame of the study spans from the late 1970s, and the advent of affordable home computers, up to 2009. So far little academic research has been conducted on the topic and the number of other publications is almost equally low. The work done by other researchers is discussed and additional connections are made to other related fields of study such as computer history and media research. The material of the study consists principally of demos, contemporary disk magazines and online sources such as community websites and archives. A general overview of the demoscene and its practices is provided to the reader as a foundation for understanding the more in-depth topics. One chapter is dedicated to the analysis of the artifacts produced by the community and another to the discussion of the computer hardware in relation to the creative aspirations of the community members.

We connect researchers, thinkers and practitioners to an international network of people changing politics.Our ideas regularly influence government policy, but we also work with companies, NGOs, colleges and professional bodies. Demos knowledge is organised around five themes, which combine to create new perspectives.The themes are democracy, learning, enterprise, quality of life and global change. But we also understand that thinking by itself is not enough. Demos has helped to initiate a number of practical projects which are delivering real social benefit through the redesign of public services. For Demos, the process is as important as the final product. We bring together people from a wide range of backgrounds to cross-fertilise ideas and experience. By working with Demos, our partners help us to develop sharper insight into the way ideas shape society. www.demos.co.uk © Douglas Rushkoff 2003 Open access. Some rights reserved.

    Market Driven Strategic Advisory EMERGING AND DISRUPTIVE TECHNOLOGY ANALYSIS 5G and Edge Computing Impact on Business Models, Service Providers, Datacenters, Applications, Business Users and Consumers https://mindcommerce.com/ Copyright 2019 ©Mind Commerce +1 206-395-9205 Market Driven Strategic Advisory EMERGING AND DISRUPTIVE TECHNOLOGY ANALYSIS Highlights and Findings • 5G Influence on Bandwidth and Data Economics: 5G will “reinvent” connectivity as there will be a very credible alternative to cable and fiber for business customers. 5G will bring about fundamental structural economic changes, such as significantly lower broadband pricing as a whole, and also much greater flexibility for enterprise, industrial, and government market segments in terms of how they connect public to private networks. • 5G Needs Edge Computing: LTE is improved with edge computing, but 5G absolutely requires it. In fact, without mobile edge computing, 5G would need to rely upon back-haul to centralized cloud resource for storage and computing, diminishing much of the otherwise positive impact of latency reduction enabled by 5G. • Mobile Edge Computing a Must for Private Wireless Networks: Enterprise and industrial segments will continue to deploy private networks utilizing LTE and WiFi. Many of these networks will evolve to 5G and include edge computing to maximize overall throughput and minimize latency, which will be crucial for certain critical communications solutions such as industrial process automation. • Combined 5G and Edge Solutions: A variety of enhanced services and new apps will be enabled, many of which will be directly or indirectly involved with smart cities, intelligent buildings, and smart homes and workplaces. Key 5G and MEC supported applications for business will be IoT connectivity, SMB/corporate mobility, and fixed wireless.

  • Avril 2021 Mettre Le Cloud Européen Au Service De L’Économie De La Vie
    Le Cloud européen : de grands enjeux pour l’Europe et cinq scénarios avec des impacts majeurs d’ici 2027-2030 Avril 2021 Mettre le cloud européen au service de l’économie de la vie. Mettre les données, virtuelles par essence, dans un stockage virtuel, était depuis longtemps une évidence prévisible, que la technologie a fini par imposer. Malheureusement, comme souvent, l’Europe a mis plus longtemps que beaucoup d’autres à le comprendre, laissant à Microsoft, Amazon et Google plus de 60% du marché du cloud public mondial. Aujourd’hui, cette absence de l’Europe est très grave et il convient d’y remédier au plus vite. D’abord, c’est un enjeu économique : D’ici à 2027, le marché du cloud en Europe pourrait atteindre plus de 260 milliards d’euros (contre 53 milliards d’euros aujourd’hui), ce qui le mettrait au même niveau que le marché actuel des télécommunications (environ 250 milliards d’euros en 2020). Et si les opérateurs de Cloud localisaient leurs opérations et leurs investissements en Europe, cela pourrait permettre en plus de créer environ 550 000 emplois entre 2021 et 2027 et déclencher des investissements significatifs (de l’ordre de 200 Md€ s sur la période 2021-2027). Cela serait aussi l’occasion de soutenir l’industrie des applications : le cloud n’est rien sans l’ensemble des services qui l’utilisent ; un cloud européen pourrait permettre de développer plus rapidement les entreprises européennes du logiciel, dans toutes les acceptions du mot. Cela permettrait aussi de développer dans un contexte sécurisé, les industries de la santé, de l’éducation, de la culture, des médias, de la sécurité, de l’assurance, de la finance ; tous secteurs fondamentaux dans la future économie de la vie.
