sagecreek writes "If you are in charge of a small network with just a few servers, you may still be doing configuration management primarily by hand. And you may take particular pride in maintaining that 'artisan' role. After all, it's mostly up to you to set up new users and their machines, fix current problems, manage the servers and their software, create databases and their user accounts, and try to keep the network and user configurations as uniform as possible despite running several different brands--and vintages--of hardware and software. However, warns infrastructure consultant John Arundel, '[b]eyond ten or so servers, there simply isn't a choice. You can't manage an infrastructure like this by hand. If you're using a cloud computing architecture, where servers are created and destroyed minute-by-minute in response to changing demand, the artisan approach to server crafting just won't work.' In his new book, Puppet 3 Beginner's Guide, Arundel emphasizes: 'Manual configuration management is tedious and repetitive, it's error-prone, and it doesn't scale well. Puppet is a tool for automating this process.'" Read below for the rest of sagecreek's review.

alphadogg writes "Ed Iacobucci, whose work on OS/2 at IBM helped fuel the PC craze and whose efforts at Citrix and VirtualWorks aimed to bring computing back under control, has died at the age of 59 from pancreatic cancer. Born in Argentina and schooled in systems engineering at Georgia Tech, Iacobucci got his career start in 1979 at IBM, where he held architecture and design leadership roles involving PC operating systems OS/2 and DOS, working closely with Microsoft in doing so (and later turned down a job there). Iacobucci left 10 years later to start thin-client/virtualization company Citrix, followed by creation of on-demand jet company DayJet, and most recently VirtualWorks, a company dedicated to managing big data sprawl. He stepped down as CEO of VirtualWorks in May because of his health."

crookedvulture writes "With its Sandy Bridge and Ivy Bridge processors, Intel allowed standard Core i5 and i7 CPUs to be overclocked by up to 400MHz using Turbo multipliers. Reaching for higher speeds required pricier K-series chips, but everyone got access to a little "free" clock headroom. Haswell isn't quite so accommodating. Intel has disabled limited multiplier control for non-K CPUs, effectively limiting overclocking to the Core i7-4770K and i5-4670K. Those chips cost $20-30 more than their standard counterparts, and surprisingly, they're missing a few features. The K-series parts lack the support for transactional memory extensions and VT-d device virtualization included with standard Haswell CPUs. PC enthusiasts now have to choose between overclocking and support for certain features even when purchasing premium Intel processors. AMD also has overclocking-friendly K-series parts, but it offers more models at lower prices, and it doesn't remove features available on standard CPUs."

First time accepted submitter rarkian writes "I am the teacher in this story. I teach Python and C++ to high school students: grades 9-12. I use CentOS 6 with DRBL to run my computer lab. Some of my students have become Linux experts. Next year I'm planning on allowing students to create and run their own VMs in a segregated LAN. Any advice on which virtualization technology to use and security concerns with allowing students to be root in a VM?"

Gonzalez_S writes "Let's say you need to give access to 100+ users to create their own virtual machines and devices (eg. switches, .., ms windows or linux family) in a manageable and secure way. Which virtualization solution would you choose? There are vmware, xen, kvm, .. based solutions, but which one would you prefer and why? The solution should be stable, manageable, scriptable and preferably have ldap integration. In this case I also need to setup a playground for IT students, next to hosting production servers on the same system."

hypnosec writes "IBM is taking its COBOL server platform to the next level by updating the mainframe platform in a bid to extend and enable its mainframes to host cloud based applications and services. The latest update is looking to add XMLS Server as well as Java 7 capabilities to the System/z COBOL platform and this update would extend the overall lifespan of COBOL by taking it up a notch and gearing it towards the cloud computing arena."

An anonymous reader writes "Andy Oram reports on the quality, security, and community driving open source adoption. 'All too often, the main force uniting competitors is the fear of another vendor and the realization that they can never beat a dominant vendor on its own turf. Open source becomes a way of changing the rules out from under the dominant player. OpenStack, for instance, took on VMware in the virtualization space and Amazon.com in the IaaS space. Android attracted phone manufacturers and telephone companies as a reaction to the iPhone.'"

First time accepted submitter anarcat writes "After two years since the last Debian release (6.0, nicknamed "squeeze"), the Debian release team has finally published Debian 7.0 (nicknamed "Wheezy"). A newly created blog has details on the release, which features multi-arch support (e.g. you can now install packages for both i386 and amd64 on the same install), improvements to multimedia support (no need for third party repositories!) and improved security through hardening flags. Debian 7.0 also ships with the controversial Gnome 3 release, and the release notes explicitly mention how to revert to the more familiar 'Gnome classic' interface. Finally, we can also mention the improved support for virtualization infrastructure with pre-built images available for Amazon EC2, Windows Azure and Google Compute Engine. Debian 7.0 also ships with the OpenStack suite and the Xen Cloud Platform. More details on the improvements can be found in the release notes and the Debian wiki." An anonymous reader points out (from the announcement) that "[t]he installation process has been greatly improved: Debian can now be installed using software speech, above all by visually impaired people who do not use a Braille device. Thanks to the combined efforts of a huge number of translators, the installation system is available in 73 languages, and more than a dozen of them are available for speech synthesis too. In addition, for the first time, Debian supports installation and booting using UEFI for new 64-bit PCs (amd64), although there is no support for Secure Boot yet."

jrepin writes "The Linux Foundation, the nonprofit organization dedicated to accelerating the growth of Linux, today announced the Xen Project is becoming a Linux Foundation Collaborative Project. Linux Foundation Collaborative Projects are independently funded software projects that harness the power of collaborative development to fuel innovation across industries and ecosystems. The Xen Project is an open source virtualization platform licensed under the GPLv2 with a similar governance structure to the Linux kernel. Designed from the start for cloud computing, the project has more than a decade of development and is being used by more than 10 million users. As the project experiences contributions from an increasingly diverse group of companies, it is looking to The Linux Foundation to be a neutral forum for providing guidance and facilitating a collaborative network."

snydeq writes "We need bare-bones Linux distros tailored for virtual machines or at least the option for installs, writes Deep End's Paul Venezia. 'As I prepped a new virtual server template the other day, it occurred to me that we need more virtualization-specific Linux distributions or at least specific VM-only options when performing an install. A few distros take steps in this direction, such as Ubuntu and OEL jeOS (just enough OS), but they're not necessarily tuned for virtual servers. For large installations, the distributions in use are typically highly customized on one side or the other — either built as templates and deployed to VMs, or deployed through the use of silent installers or scripts that install only the bits and pieces required for the job. However, these are all handled as one-offs. They're generally not available or suitable for general use.'"

dcblogs writes "Virtualization, cloud services and software-as-a-service (SaaS) is making it much easier to shift IT infrastructure operations to service providers, and that is exactly what many users are doing. Of the new data center space being built in the U.S., service providers accounted for about 13% of it last year, but by 2017 they will be responsible for more than 30% of this new space, says IDC. 'We are definitely seeing a trend away from in-house data centers toward external data centers, external provisioning,' said Gartner analyst Jon Hardcastle. Among those planning for a transition is the University of Kentucky's CIO, who wants to reduce his data center footprint by half to two thirds. He expects in three to five years service provider pricing models 'will be very attractive to us and allow us to take most of our computing off of our data center.' IT managers says a big reason for the shift is IT pros don't want to work in data centers at small-to-mid size firms that can't offer them a career path. Hank Seader, managing principal of the Uptime Institute, said that it takes a 'certain set of legacy skills, a certain commitment to the less than glorious career fields to make data centers work, and it's hard to find people to do it.'"

An anonymous reader writes "Anandtech compares the Boston Viridis, a server with Calxeda's ARM server technology, with the typical Intel Xeon technology in a server environment. Turns out that the Quad ARM A9 chip has it weaknesses, but it can offer an amazing performance per Watt ratio in some applications. Anandtech tests bandwidth, compression, decompression, building/compiling and a hosted web environment on top of Ubuntu 12.10." At least in their tests (highly parallel, lightweight file serving), the ARM nodes offered slightly better throughput at lower power use, although from the looks of it you'd just be giving money to the server manufacturer instead of the power company.

hypnosec writes "Linux KVM has been ported to ARM64 just ahead of the release of the architecture, it has been revealed. Just last year ARM KVM virtualization support for Cortex-A15 32bit ARM processor was published. Marc Zyngier of ARM released a set of 29 patches that contained the implementation of KVM for ARM that depends on the pre-arm64 rework as well as tiny perf patch published earlier. Some of the newly released port are support for 4k and 64k pages and 32-bit as well as 64-bit guests."

On the heels of their December release, the 13.02 release of the Genode multi-server microkernel OS framework continues to deliver major new features. Under the hood, there's support for the IOMMU, bringing safe bus master DMA to userspace drivers (overcoming one of the final advantages monolithic kernels had). They've also added full virtualization support, good enough to boot Linux as an application. In the cool department, they've added a new low latency audio interface that could very well pave the way for something akin to JACK, and right now provides a lightweight way for the system to beep at you in real time . A few more libraries have been ported (libssh, curl, iconv) in preparation for a port of git to the Noux native GNU runtime. There are also a bunch of other improvements to their NOVA microkernel, support for running on the Exynos 5250 and Freescale i.MX53, a new console multiplexer, improvements to the display server, simplification of the base libraries, and more. I'll be attempting to build it and give it a spin to see how well it works in practice sometime soon.

A reader sends this quote from ZDNet: "Software that allows Windows apps to run on Android devices was demoed at the Fosdem 2013 open source conference this weekend. The demo by Alexandre Julliard, one of the original developers of Wine, showed Wine running on an emulated Android environment. Phoronix reports the performance of Wine on Android to be 'horrendously slow' but says these problems were attributed to it running on an emulated environment rather than a native Android OS. ... The makers claim it bypasses many performance and memory penalties of other methods for simulating computing environments, such as running virtual machines, by translating Windows API calls into POSIX calls on the fly. The Android OS predominantly runs on ARM-based devices today, and a separate demo at the Fosdem conference showed Wine running on ARM-based hardware. There was no news on when support for ARM-based devices or Android will be added to a publicly available Wine release."

An anonymous reader writes "WindowsAndroid is a very cool tool from the Beijing-based startup SocketeQ that lets you run Android 4.0 (Ice Cream Sandwich) as a native application on Windows Vista, Windows 7, or Windows 8 machines. The creators tell us they have a deep background in virtualization, operating system, and graphics technologies, and have been working on the project for years. Essentially, WindowsAndroid allows you not only to execute Android apps on your Windows computer, but also use the browser, not to mention every other component of the operating system."

kthreadd writes "The Red Hat Enterprise Linux 5 derivative CentOS version 5.9 has been released just 10 days after its upstream provider. According to the release notes a number of changes have been made. New packages available in CentOS 5.9 includes for example OpenJDK 7 and Rsyslog 5. Several drivers have also been updated in the kernel which has been updated to version 2.6.18-348, including support for Microsoft's virtualization environment Hyper-V." CentOS has been plugging away now for nearly 10 years.

MojoKid writes "NVIDIA made some bold moves at their CES 2013 press conference and announced a couple of potentially game changing products. GeForce GRID is a cloud gaming solution. It allows PC game content to be run and rendered in the cloud and then streamed to any device that can run the GRID receiver utility, like a Smart TV, tablet, or a smartphone. GeForce GRID server architecture combines an NVIDIA-designed server packed with GPUs with NVIDIA-developed software and virtualization layer. A rack of 20 GRID servers was shown, powered by 240 GPUs, capable of 200 TFLOPS and roughly equivalent to the performance of 720 Xbox 360 consoles. The biggest news to come out of NVIDIA's press conference, however, had to do with Tegra 4. Not only was the next-gen SoC officially unveiled, but a new portable gaming device based on Tegra 4, dubbed Project SHIELD, was also demoed. NVIDIA's Tegra 4 builds upon the success of the Tegra 3 by incorporating updated ARM15-based CPU cores with 72 custom GeForce GPU cores, which offer up to 6x the performance of Tegra 3. The A15 cores used in Tegra 4 are up to 2.6x faster than the A9-class cores used in Tegra 3. As a companion to the Tegra 4, NVIDIA also took the wraps off of their new Icera i500 programmable 4G LTE modem processor. Icera i500 features 8 custom, programmable processor cores and is approximately 40% smaller than many fixed function modems. The biggest surprise to come out of NVIDIA's press conference was Project SHIELD, a Tegra 4-powered mobile gaming device running Android that's sure to put Microsoft, Sony, and Nintendo on high alert. Project SHIELD offers a pure Android experience without any skinning or other customizations, save for the SHIELD app environment, that can play any Android game. Project SHIELD has the ability to stream PC games from a GeForce GTX-equipped PC as well. The device is shaped much like an Xbox 360 game controller, but features a 5", flip-out capacitive touch display with a 720P resolution. The device can also stream to an HD TV via HDMI or a WiDi-like wireless dongle. In fact, CEO Jen-Hsun Huang showed Project SHIELD playing a 4K video on an LG 4K TV."

MojoKid writes "Intel has been promising it for months, and now the company has officially announced the Intel Atom S1200 SoC. The ultra low power chip is designed for the datacenter and provides a high-density solution designed to lower TCO and improve scalability. The 64-bit, dual-core (four total threads with Hyper-Threading technology) Atom S1200 underpins the third generation of Intel's commercial microservers and feature a mere 6W TDP that allows a density of over 1,000 nodes per rack. The chip also includes ECC and supports Intel Virtualization technology. Intel saw a need for a processor that can handle many simultaneous lightweight workloads, such as dedicated web hosting for sites that individually have minimal requirements, basic L2 switching, and low-end storage needs. Intel did not divulge pricing, but regardless, this device will provide direct competition for AMD's SeaMicro server platform." Amazing that it supports ECC since Intel seems committed to making you pay through the nose for stuff like that.

Lucas123 writes "Next year, smart phones will begin shipping with the ability to have dual identities: one for private use and the other for corporate. Hypervisor developers, such as VMware and Red Bend, are working with system manufacturers to embed their virtualization software in the phones, while IC makers, such as Intel, are developing more powerful and secure mobile device processors. The combination will enable mobile platforms that afford end users their own user interface, secure from IT's prying eyes, while in turn allowing a company to secure its data using mobile device management software. One of the biggest benefits dual-identity phones will offer is enabling admins to wipe corporate data from phones without erasing end users profiles and personal information."
