EVALUATION OF CLOUD COMPUTING SERVICES . To the consumer, the capabilities available for provisioning often appear unlimited and can be appropriated in any quantity at any time. The answer is Mainframes. Dans ce contexte, l'ancêtre du SaaS correspondait au ASP[16]. Florian Ok merci, c'est plus compréhensible Stephane.Cadoret 6 février 2013 à 22:05 (CET) Sécurité du Cloud. Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. Les technologies du cloud computing ont permis la mise au point de solutions de mégadonnées et de l'informatique ubiquitaire. AU - Hong, Tae Young. L'« élasticité » du nuage permet de fournir des services évolutifs et peut permettre de supporter des montées en charge. Hybrid cloud adoption depends on a number of factors such as data security and compliance requirements, level of control needed over data, and the applications an organization uses.[107]. The capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The pricing model for SaaS applications is typically a monthly or yearly flat fee per user,[84] so prices become scalable and adjustable if users are added or removed at any point. [83] Load balancers distribute the work over the set of virtual machines. Le cloud computing /klaʊd kəmˈpjuːtɪŋ/[1], en français l'informatique en nuage[2],[3] (ou encore l'infonuagique[3] au Canada), correspond à l’accès à des services informatiques (serveurs, stockage, mise en réseau, logiciels) via Internet (le « cloud » ou « nuage ») à partir d’un fournisseur[4]. [citation needed], An alternative approach is to deploy a tool that processes in the cloud itself. La popularisation d'Internet grâce aux navigateurs (1996) amena des cadres de Compaq et Sean O'Sullivan (en) à proposer le concept et le terme 'cloud computing', mais l'idée ne rencontra pas de succès à l'époque. [127][126] Identity management systems can also provide practical solutions to privacy concerns in cloud computing. Cette approche de type PaaS a recours à des API et à des kits de développement logiciel (SDK) pour relier les applications mobiles au back-end Cloud[14]. [47][48][49], In May 2012, Google Compute Engine was released in preview, before being rolled out into General Availability in December 2013. Au début des années 2000 sont apparus des hébergeurs web capables d'héberger des applications dans leurs locaux informatiques. For instance, sworn translators working under the stipulations of an NDA, might face problems regarding sensitive data that are not encrypted.[136]. [8], The availability of high-capacity networks, low-cost computers and storage devices as well as the widespread adoption of hardware virtualization, service-oriented architecture and autonomic and utility computing has led to growth in cloud computing. Cloud computing Architectures, services et risques Giovanna Di Marzo Serugendo Institute of Information Service Science Giovanna.Dimarzo@unige.ch iss.unige.ch . Andy Hertzfeld: "The beauty of Telescript," says Andy, "is that now, instead of just having a device to program, we now have the entire Cloud out there, where a single program can go and travel to many different sources of information and create a sort of a virtual service. Technical outages are inevitable and occur sometimes when cloud service providers (CSPs) become overwhelmed in the process of serving their clients. Un nuage communautaire utilise une infrastructure provenant d'un ensemble de membres partageant un intérêt commun, comme dans le cas des milieux universitaires pour des études de grande envergure[5]. [130] Physical control of the computer equipment (private cloud) is more secure than having the equipment off-site and under someone else's control (public cloud). dPaaS users access data through data-visualization tools. Both AHP and LSP methods are widely used evaluation methods for different research areas. [129], There is the problem of legal ownership of the data (If a user stores some data in the cloud, can the cloud provider profit from it?). [117], The issues of transferring large amounts of data to the cloud as well as data security once the data is in the cloud initially hampered adoption of cloud for big data, but now that much data originates in the cloud and with the advent of bare-metal servers, the cloud has become[118] a solution for use cases including business analytics and geospatial analysis.
