How Cloud Computing Works"
­Let's say you're an executive at a large corporation. Your particular responsibilities include making sure that all of your employees have the right hardware and software they need to do their jobs. Buying computers for everyone isn't enough -- you also have to purchase software or software licenses to give employees the tools they require. Whenever you have a new hire, you have to buy more software or make sure your current software license allows another user. Soon, there may be an alternative for executives like you. In a cloud computing system, there's a significant workload shift. There's a good chance you've already used some form of cloud computing. What makes up a cloud computing system?

NASA’s Nebula: The Cloud in a Container « Data Center Knowledge The Verari data center container housing the NASA Nebula cloud computing application arrives at Ames Research Center in Mountain View, Calif. What do you get when you combine cloud computing and data center containers? You get NASA’s Nebula, the space agency’s new data powerhouse, which provides on-demand computing power for NASA researchers. Nebula was recently cited by federal CIO Vivek Kundra as an example of the government’s ability to “leverage the most innovative technologies.” The Nebula application lives in a 40-foot container at the NASA Ames Research Center in Mountain View, Calif. The “data center in a box” was built inside a FOREST container from Verari Systems, which is filled with Cisco Systems’ Unified Computing System and servers from Silicon Mechanics. Science Compute Power on Demand Nebula is a self-service platform built from open source software that provides high capacity computing, storage, and network connectivity for NASA research.

Cloud Computing Certification Schemes List - CCSL - Digital Agenda for Europe What is a cloud certification scheme? Before buying a cloud service, customers want to know if the service is secure and reliable. But cloud computing services are complex and built up from many different ICT components (cables, large data centers, software, et cetera), so it is hard for individual customers to check all the technical details by themselves. Cloud providers have many customers (this is the main idea of cloud computing) so if all customers would check their security requirements separately, then this would mean double work. If each customer would want to do an on-site audit, for example, there would be long cues at the gates of data centers. Now, the idea of a certification scheme is to check one basic set of security requirements, once for all customers. How to use this list? CCSL gives an overview of different existing certification schemes which could be relevant for cloud computing customers. Certification schemes

OpenStack Open Source Cloud Computing Software Cloud computing, smart city, cybersécurité : les innovations à suivre d'ici 2019, selon IBM A lire sur: IBM publie comme chaque année son "5 in 5", un choix de cinq technologies innovantes que le pionnier de l'informatique pense voir mises en œuvre d'ici cinq ans. Cette année, ses ingénieurs misent avant tout sur les technologies cognitives et le cloud computing – domaines dans lesquels IBM excelle – pour changer notre futur. L'école va apprendre des élèves La classe du futur apprendra de chaque élève au cours de son cursus scolaire, les aidant à maîtriser les compétences nécessaires pour atteindre leurs buts.

How Does Cloud Computing Work? [Technology Explained] Before we dig further into how does cloud computing work, first let’s understand what the term “cloud“ refers to. The concept of the cloud has been around for a long time in many different incarnations in the business world. It mostly means a grid of computers serving as a service-oriented architecture to deliver software and data. Most websites and server-based applications run on particular computers or servers. What differentiates the cloud from the way those are set up is that the cloud utilizes the resources from the computers as a collective virtual computer, where the applications can run independently from particular computer or server configurations. With broadband internet, the need to have the software run on your computer or on a company’s site is becoming less and less essential. How is that done? To understand how does cloud computing work, imagine that the cloud consists of layers — mostly the back-end layers and the front-end or user-end layers.

Cours complet : Cloud computing et Saas Internet est apparu dans les années 1960, mais il a fallu attendre les années 1990 pour qu'il ait un impact sur le monde de l'entreprise. Le World Wide Web est né en 1991 et, en 1993, le navigateur Mosaic a été lancé. Il permettait aux utilisateurs de consulter des pages web qui comprenaient des textes et des images. C'était le début des premiers sites web d'entreprise et, bien entendu, la plupart de ceux-ci appartenaient à des sociétés dans la technologie et les ordinateurs. Lorsque la vitesse et la fiabilité des connexions s'est améliorée, un nouveau type d'entreprise est apparue : les fournisseurs d'applications en ligne (Application Service Provider, ASP). Les ASP utilisaient des applications métiers et les exécutaient pour leurs clients. Mais il a fallu attendre les années 1990 pour que le cloud computing fasse son apparition. Depuis, le cloud n'a cessé de croître : en 2013, les dépenses mondiales en services cloud étaient estimées à 47 milliards de dollars.

Discussion on iCloud in the business setting: Evaluating the pros and cons Erik Eckel looks at iCloud from the perspective of the small business. Can it be utilized for more than personal storage? Apple's iCloud announcement earned quite a few headlines. But those aren't the features compelling small organizations to leverage iCloud. Why iCloud? Small businesses that wish to simply sync mail, contacts and calendar information across multiple devices will find iCloud an easy choice. iCloud will also sync iWork documents, spreadsheets and presentations across the common devices numerous small businesses use: iPhones, iPads and a Mac or Windows PC. Where iCloud will really shine, though, is providing additional protection against some of the most vexing frustrations users encounter. Why iCloud may not be right It remains to be seen whether users must use an email account to leverage iCloud-synced mail, contacts and calendar. Not all apps may offer iCloud integration, which means users may find some apps incompatible with the backup features. My prediction

Why NASA uses Open Source - InternetNews:The Blog - Sean Michael Kerner From the 'Best Tech Isn't Necessarily in Area 51' files: With Billions of dollars and massive technology needs that are literally out-of-this-world, NASA has a lot of unique computing requirements. As it turns out, some of those requirements can be fulfilled by technology that isn't all that different from what regular enterprises need too. In order to save the data from distant spacecraft, satellites and other scientific endeavors, NASA is leveraging open source tech (including Ubuntu Linux) and regular enterprise networking components to meet their mission. I had the privilege of speaking with NASA's CTO for IT Chris Kemp this week around the OpenStack project in which NASA is participating. Kemp told me that NASA's Nebula cloud IT environment was built for science and research and has been optimized for low cost and massive scalability. He added that NASA is using KVM on Ubuntu's Lucid LTS.

Stratégies – Savoir mesurer les enjeux et les risques du Cloud Computing pour votre direction générale | Office365 Undercover Depuis quelques années, je m’occupe d’accompagner les entreprises à mettre en œuvre les services issus du Cloud Computing, et force est de constater que ce domaine ne cesse de me surprendre. Par exemple, dans le dernier numéro, sur un ton humoristique, j’ai évoqué avec vous les problèmes des entreprises à tenter de contrôler la production par les utilisateurs de fichiers de plus en plus nombreux. Ce que j’oublie souvent de préciser, c’est que mes articles sont la plupart du temps inspirés par les sujets que me confient les entreprises afin d’y apporter un éclairage. C’est ainsi que l’article sur l’infobésité du mois dernier fait suite à un retour d’expérience : Une entreprise a fait appel à mes services pour comprendre pourquoi l’activité de leurs baies de stockage semblait depuis quelques temps en baisse d’activité ? Représentation d’une salle informatique d’entreprise en 2020 Oui, mais début des problèmes de fiscalité. Après tout, on peut toujours dire que ça n’arrive qu’aux autres… i.
