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.

  • 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.

All rights reserved. Unauthorized reproduction prohibited. Open Computing is for Everyone and is Here to Stay 02 Catalyst Over the last 20 years, the world has become more and more digital and the data center (DC) has become key to business success, especially when it comes to the skyrocketing e-commerce, internet content, and cloud services industries. The larger the scale, the bigger the impact simple design improvements have, be that in the physical or IT aspects of a data center. It is no surprise then that, as companies like Facebook, Amazon, and Alibaba became leaders in digital industry, the re- engineering of their DC equipment became a top priority. Three design considerations stand out: power efficiency, manageability, and ease of deployment. In 2009, Facebook began an initiative to design its own DC IT and physical equipment to create the world’s most energy-efficient data center that would enable hyperscale computing at the lowest cost possible. Two years later, it shared its designs and results with the public, demonstrating a data center that was 38% more energy efficient with a 24% reduction in operational expenditure (opex).
