Cientos de miles de centros de datos en todo el mundo albergan los millones de servidores y sistemas de almacenamiento necesarios para mantener la actividad en la era de Internet. Millones de personas con sus ordenadores encendidos permanentemente. Máquinas trabajando 24 horas al día que consumen una enorme cantidad de energía tanto para su funcionamiento, como para su refrigeración.
Cooperating with file-sharing networks could avert congestion.
Cloud computing isn't going to dominate the tech landscape but will raise a ruckus for software vendors. Google and Amazon will be cloud-computing winners, but the spoils will be relatively small. And there's a race to deliver a cloud developer stack for both consumers and enterprise customers.
Those are some of the key takeaways from a Bernstein Report dubbed The Long View: Netbooks, Wireless and Cloud Computing--Client Software's Imperfect Storm.
Grid computing technology has long been the darling of cash-strapped academics in desperate need of raw processing power. Now a groundbreaking European research effort has created an industrial-strength platform already appearing in commercial applications.
Paris, Munich, Campos, December 1st 2008 - the Foundation for a Free Information Infrastructure (FFII) released during the Open World Forum the first conclusions of its workgroup on Total Information Outsourcing (TIO). TIO is a recent trend in the management of corporate information systems which consists of outsourcing critical information infrastructure to Web based services. This creates new risks for Freedom and Competition. The FFII TIO workgroup has identified 7 rights that address these risks. If they are satisfied, outsourced software and data enjoys the same freedom and security that is available with in-house Open Source / Free Software solutions.
A couple of months ago, Hugh Macleod created a bit of buzz with his blog post The Cloud's Best Kept Secret. Hugh's argument: that cloud computing will lead to a huge monopoly. Of course, a couple of weeks ago, Larry Ellison made the opposite point, arguing that salesforce.com is "barely profitable", and that no one will make much money in cloud computing.
Intel está creando una familia de herramientas para ayudar a los desarrolladores a aprovecharse de las ventajas de su próximo procesador Larrabee.
Grid technology developed by European researchers offers a new way to do business, with partners working simply, seamlessly and ‘virtually’ around a common goal. It is already having a big impact, in a variety of applications.
European researchers have developed a suite of tools that make it simple, safe and secure to deploy grid computer systems across corporations and throughout the supply chain. The work means that virtual organisations can become a reality.
Every day people rely on search engines to find specific content in the many terabytes of data that exist on the Internet, but have you ever wondered how this search is actually performed? One approach is Apache's Hadoop, which is a software framework that enables distributed manipulation of vast amounts of data. One application of Hadoop is parallel indexing of Internet Web pages. Hadoop is an Apache project with support from Yahoo!, Google, IBM, and others. This article introduces the Hadoop framework and shows you why it's one of the most important Linux®-based distributed computing frameworks.
Citrix planea llevar la virtualización del escritorio al iPhone y otros dispositivos móviles el próximo año, tal y como han declarado fuentes de la propia compañía.
The largest share of data traffic on the Internet is attributable to peer-to-peer networks which are independent of defined Internet Service Providers. The EU project SmoothIT under the leadership of Burkhard Stiller from the University of Zurich now aims to develop economic incentive schemes with which providers should more efficiently adapt their networks to peer-to-peer use and therefore be able to offer cheaper and simultaneously better services.
Despite complaints that x86 chips can't scale properly for high performance computing, Intel and AMD say they have solutions in the works.
While 2008 has been a tumultuous year in business, there have also been a series of developing trends that are quietly transforming the traditional strategies and the standard operating procedures of IT. Here are the five trends that having the biggest impact.
Having coined the phrase "the network is the computer" more than a decade ago Sun Microsystems could expect to be leading the march towards cloud computing, but in some ways it is still at the start line.
A new survey finds the economic downturn could make virtualization even hotter. But SOA might suffer for the same reason.
One of the biggest challenges for managers of high-production computer systems is testing new code or hardware before it is rolled out across thousands of nodes. Something may work fine on a single server, but it could collapse as it is extended across many more nodes. Compounding the problem is that supercomputer cycles are so in demand these days that getting time on the big iron for testing purposes isn't very likely.
With all the recent hoopla about GPU-accelerated HPC, reconfigurable computing with Field Programmable Gate Array (FPGA) has been getting proportionally less attention. While NVIDIA has led the GPU push in HPC, there is no single vendor in the reconfigurable computing space that has jumped into the driver's seat. That hasn't kept a variety of smaller players from trying.
A push to broaden access to high-performance systems could help U.S. companies become more competitive.
Salesforce and Google have extended their strategic partnership with Force.com for Google App Engine, essentially bridging the two cloud-based application development environments. App Engine applications, which are typically consumer apps, will be able to access enterprise data and services via the Force.com API.
