Cloud computing

Le cloud computing[1], ou l’informatique en nuage ou nuagique ou encore l’infonuagique (au Québec), est l'exploitation de la puissance de calcul ou de stockage de serveurs informatiques distants par l'intermédiaire d'un réseau, généralement Internet. Ces serveurs sont loués à la demande, le plus souvent par tranche d'utilisation selon des critères techniques (puissance, bande passante, etc.) mais également au forfait. Category:Cloud computing. The Top 150 Players in Cloud Computing. Cloud Expo Early Bird Savings A robust ecosystem of solutions providers is emerging around cloud computing.

The Top 150 Players in Cloud Computing

Here, SYS-CON's Cloud Computing Journal expands its list of most active players in the fast-emerging Cloud Ecosystem, from the 'mere' 100 we identified back in January of this year, to half as many again - testimony, if any further were needed, to the fierce and continuing growth of the "Elastic IT" paradigm throughout the world of enterprise computing. Editorial note: The words in quotation marks used to describe the various services and solutions in this round-up are in every case taken from the Web sites cited.

As ever we encourage software engineers, developers, IT operations managers, and new/growing companies in every case to "suck it and see" by downloading or otherwise sampling the offering in question for themselves. Understanding the Cloud Computing/SaaS/PaaS markets: a Map of the Players in the Industry. The Cloud Computing/SaaS/PaaS space is loaded with interesting vendors, and the space is booming.

A startup that lets you have your own cloud servers at home is part of a movement that is turning its back on conventional cloud computing IS THIS the death of the cloud as we know it?

Personal clouds let you take control of your own data - tech - 31 May 2013

Space Monkey certainly seems to think so – it is planning to build a better one. When its Kickstarter campaign ended last week, the startup had received more than three times its $100,000 funding target. Set to launch in the next few months, Space Monkey aims to replace public cloud service providers such as Dropbox and Google Drive with a cloud of thousands of devices that sit in our homes. For a monthly fee, Space Monkey will lease subscribers a device containing a 2-terabyte hard drive and software that connects to all other Space Monkey devices on the internet. Only half the storage space is for you – the rest is filled with other subscribers' data. But it is likely to be concerns about data ownership that prompt people to make the switch. "Even if you know what you're doing it's a pain," says Mortier.

The People’s Cloud and the inevitable talent migration to P2P: the future of cloud computing is p2p!

Vinay Gupta argues that Bitcoin and Bittorrent show that the future of Cloud Computing is P2P: “1> Computer power is an ever-more-abundant resource. As a result, the data center is doomed for a variety of reasons. Yet even in such times, the temporary efficiency of the data center is bought at the price of centralization and inevitable monitoring. Bitcloud. Personal Clouds.

Estimates vary about the number of connected devices there will be as the internet of things shapes up – a recent Gartner estimate was 26 billion by 2020 — but everyone agrees there will be a ton.

Prepping the cloud for the internet of things

The numbers are staggering even when it comes to personal electronic devices like smartphones, tablets and game consoles. Just five years ago, U.S. households averaged just one web-connected device, now the average is 5 or 6, according to Deepfield CEO Craig Labovitz, whose company keeps track of the traffic flying around the web. But the really mind-blowing numbers are for the other devices — those that talk to each other, not to us. Gartner’s 26 billion number for example, doesn’t even count people-oriented smartphones and tablets.

So the endpoints may be cool and numerous, but the more interesting story will be how all the data they spew will be handled and how the internet infrastructure itself — with a big assist from cloud computing — will adapt to deal with it.

La valorisation de la chaleur des datacenters

Les réflexions des gestionnaires de datacenters sur les moyens de valoriser la chaleur "perdue" de leur centre de données se sont concrétisée par plusieurs projets en France. Focus. Garantir la sécurité et la disponibilité continue des données de leurs clients tout en réalisant plus d'opérations informatiques en consommant moins d'énergie, tel est l'enjeu auquel se confrontent les gestionnaires de datacenters depuis que leur impact en terme de consommation électrique a été pointé du doigt par plusieurs ONG.

En France, ces usines du numérique sont désormais une centaine et consommeraient environ 9% de l'électricité, une consommation en hausse de 10% par an. Des milliards de kWh pour des milliards de données informatiques - Datacenter : l'efficience énergétique au centre des préoccupations. Le secteur des Technologies de l'information et de la Communication connait une croissance exponentielle du nombre de données et des besoins de traitement qui n'est pas sans impact sur la consommation d'énergie et les émission de CO2.

Des milliards de kWh pour des milliards de données informatiques - Datacenter : l'efficience énergétique au centre des préoccupations

A chaque mail envoyé, à chaque requête sur un moteur de recherche, à chaque commande en ligne ou vidéo visionnée et photo partagée…, ce sont des milliards de données informatiques, provenant de milliers de serveurs qui sont réceptionnés, traités et stockés via les datacenters ou "usines numériques". The Past, Present, and Future of Data Storage. As we approach the end of 2011 and look forward to another year, we pause to reflect on the long history of data storage.

Mankind's ability to create, process, store, and recall information is light years ahead of the days of cave paintings and engravings on stone tablets. Vast amounts of information can be stored on drives smaller than your thumb, and data centers are cropping up at an increasingly high rate. What does the future of data storage hold? Are we really that close to holographic drives? Welcome to Cloud Foundry. Is cloud computing more than just smoke? The growing buzz around cloud computing sounds eerily familiar to the utility computing noise of a few years ago. But there is a difference--or at least people in the business swear there is. In reading blogs and speaking to a few people, I've found that cloud computing does indeed rehash some of the ideas of the past, but there are significant technology advances, notably virtualization, that set it apart.

One such cloud company, Elastra, launched on Tuesday its server for public and private clouds. Executives at another start-up, 3Tera, told me on Monday that later this year their AppLogic "grid operating system" will let people use a single tool to deploy applications that run on a mix of Linux, Windows, and Solaris machines. What's the link between cloud and utility computing? This makes sense for people who don't want to invest in building their own data centers or don't want to buy all the hardware required to handle "peaks" in demand. Cloud computing: Pros and cons. Network World - ON THE UPSIDE1. Fast start-up "Cloud computing is really a no-brainer for any start-up because it allows you to test your business plan very quickly for little money. SaaS Soup: Navigating the "as a Service" Acronyms: CaaS, DaaS, DBaaS, PaaS, SaaS, XaaS. Ever wonder what all the "aaS" acronyms mean?

Do you want to understand how they relate to each other? This blog entry will help. I have created a map of many of the "as a Service" terms you will see in IT and have grouped them according to category. I have also provided an explanation and links for further reading for each so you can quickly come up to speed on all. I put this together because I am working on the second edition of a visual map of the SaaS, PaaS, and Cloud Computing industries that I released last month. Map of the "as a Service" Terms This graphic shows the groupings of the "as a Service" terms that you may encounter in the IT industry.

Deciding the merits and demerits of cloud computing The relative popularity of the cloud computing business model deserves a debate. It is always easy to wax lyrical about the merits of a new technological innovation without looking at some of the disadvantages that might accrue as a result of that innovation.

When you look at the specific example of the cloud computing, the dangers of a biased view become apparent. Computing Technology. The Dangers Of Externalizing Knowledge. Contemplating the shortcomings of the younger generation has ever been a hobby of the elder. As I start to transition to the latter population (perhaps a bit early for my age), I’ve found myself worrying more and more about the kids, and how little they seem to appreciate things. That kind of complaint is neither constructive or original. But the fact is that the kids are growing up pretty weird these days, because of the way technology has outpaced our institutions of learning and standards of knowledge. The short attention span and reliance on non-text media are to be expected in an age where attention is indulged by on-demand information, and the effects of these things will continue to be written about, rightly and wrongly.

There is a more subtle and insidious trend, however, that may prove to be more damaging than tech-born changes in learning modality. It’s a process that has been going on for a long time, but that recent developments may push to the breaking point. Dossiers > La dématérialisation : état des lieux et pistes de réflexion > Conclusion. Pour conclure, la dématérialisation promet beaucoup et, comme toute véritable évolution, ses vertus et ses gouffres ne sont pas isolables. Mais comme on applaudit davantage qu'on ne s'inquiète, je prends le parti pour cette conclusion d'une mise en garde. Eight ways that cloud computing will change business. When a major change arrives on the IT scene it's not always clear what the implications will be, if any, and so for large organizations a risk-managed wait-and-see attitude tends to prevail. Occasionally however some shifts offer cost savings, improvements to operations, or ways to tackle business problems that offer significant strategic advantage.

The larger the benefit in one or more of these areas, then the more strategic the advance is and the greater potential it will impact the bottom line. 10 Cloud Predictions for 2011 from Forrester's James Staten - ReadWriteCloud.

Analyzing the Differences between Cloud Computing and Virtualization. Virtualization When we talk of virtualization in computing, the implication will be that we are somehow using the internet to carry out activities that were previously done offline. It means that whoever is running the organization has decided that they would like to take control of the activities of that activity by going online.

Virtualization therefore always associates with technological development.
