Les principes sous-jacents au cloud computing remontent aux années 1950 (longtemps avant que ne naisse l'expression « cloud computing »). The answer is Mainframes. "[72], IaaS-cloud providers supply these resources on-demand from their large pools of equipment installed in data centers. Les données peuvent être découpées et chiffrées avant d’être envoyées vers le cloud décentralisé. Quelle est la différence entre les termes "GRID computing" et "Cloud Computing" Je crois que la différence est que, dans le GRID computing, on est maître des ordinateurs qui partagent le calcul (on les achète, on les met en réseau, on les administre soi-même, etc. (2013): 1–1. In this model, the cloud user patches and maintains the operating systems and the application software. En, mutualisation : elle permet de combiner des ressources hétérogènes (matériel, logiciel, trafic réseau) pour servir plusieurs consommateurs à qui les ressources sont automatiquement attribuées, paiement à l'usage : la quantité de service consommée dans le, l'utilisation des réseaux publics, dans le cas du, les entreprises perdent la maîtrise de l'implantation de leurs, les entreprises n'ont plus de garanties (autres que contractuelles) de l'utilisation qui est faite de leurs données, puisqu'elles les confient à des tiers, des questions juridiques sont posées par l'absence de localisation précise des données du, comme les logiciels installés localement, les services de, du fait que l'on ne peut pas toujours exporter les données d'un service. Virtualization software separates a physical computing device into one or more "virtual" devices, each of which can be easily used and managed to perform computing tasks. Pour les fournisseurs, le développement du cloud computing entraîne le développement des centres de données ou centres de traitement de données. Steve Wozniak, cofondateur d'Apple, prévoit également des problèmes avec le développement croissant du cloud computing et l'externalisation des données[57]. [56][101], Several factors like the functionality of the solutions, cost, integrational and organizational aspects as well as safety & security are influencing the decision of enterprises and organizations to choose a public cloud or on-premise solution.[102]. Les applications et les données ne se trouvent plus sur l'ordinateur local, mais dans un nuage composé de serveurs distants interconnectés. "What can OpenStack adopt from a Ganeti-based open-source IaaS?." If the connection to the user is relatively close, it may be designated an edge server. [141], The issue of carrying out investigations where the cloud storage devices cannot be physically accessed has generated a number of changes to the way that digital evidence is located and collected. [106] This example of hybrid cloud extends the capabilities of the enterprise to deliver a specific business service through the addition of externally available public cloud services. These are distributed systems and its peripherals, virtualization, web 2.0, service orientation, and utility computing. To accommodate a large number of cloud users, cloud applications can be multitenant, meaning that any machine may serve more than one cloud-user organization.

Un nuage public est mis à disposition du grand public. Quatre éditeurs de logiciels libres (IELO, Mandriva, Nexedi et TioLive) ont fondé la Free Cloud Alliance (FCA) le 25 mars 2010[25]. T1 - Evaluation of P2P and cloud computing as platform for exhaustive key search on block ciphers. The computer utility could become the basis of a new and important industry. ». Les principaux services proposés en cloud computing sont le SaaS (Software as a Service), le PaaS (Platform as a Service) et le IaaS (Infrastructure as a Service) ou le MBaaS (Mobile Backend as a Service). [82] In the SaaS model, cloud providers install and operate application software in the cloud and cloud users access the software from cloud clients. En France, dans le cadre des investissements d'avenir, deux consortiums, Cloudwatt mené par Orange et Thales[28], et Numergy, mené par SFR et Bull[29], ont été mis en place à la suite d'un appel à projet gouvernemental[30]. It can improve business, but every step in the project raises security issues that must be addressed to prevent serious vulnerabilities. I'd offer to rewrite it, but I don't know the first thing about the subject. To provide the needed services, cloud computing service providers are focusing on more specialized aspects such as (SLAs) service-level agreements. Services include user management, push notifications, integration with social networking services[87] and more. [94] FaaS is included under the broader term serverless computing, but the terms may also be used interchangeably. Cloud computing Architectures, services et risques Giovanna Di Marzo Serugendo Institute of Information Service Science Giovanna.Dimarzo@unige.ch iss.unige.ch . La première initiative concerne la création d'un environnement distribué (cloud computing test bed) facilitant la recherche et les tests de logiciels, d'administration de centres de données et de matériels associés à l'informatique dans le nuage à une échelle jamais atteinte. iPaaS enables customers to develop, execute and govern integration flows. Les États-Unis détiennent la plus grande part du Cloud, cadré par une loi spécifique : le Cloud Act[59]. By switching traffic as they saw fit to balance server use, they could use overall network bandwidth more effectively. utilisation and efficiency improvements for systems that are often only 10–20% utilised. Mais si la dématérialisation simplifie la technique, les à côtés se complexifient, que ce soit le côté légal, les garanties de niveaux de performance et de disponibilité ou SLA, la sécurité et, enfin, la réversibilité. Cloud computing is beneficial to many enterprises; it lowers costs and allows them to focus on competence instead of on matters of IT and infrastructure.
