    [EN] Azure passa a oferecer Clear Linux da Intel

    Microsoft announced today that it has added support for the Intel-backed Clear Linux distribution in instances for its Azure public cloud platform.

    It’s the latest in a lengthy string of Linux distributions to become available on the company’s Azure cloud. Microsoft already supports CentOS, CoreOS, Debian, Oracle Linux, Red Hat Enterprise Linux, SUSE Enterprise Linux, OpenSUSE and Ubuntu in Azure instances.

    The new distro is available in three versions from Microsoft – first, in a stripped-down, simple VM designed for maximum customizability, second, in a Docker-based container runtime, and, finally, in a “sample solution image” designed for machine learning applications, to demonstrate some of the possibilities.

    Clear Linux is a lightweight Linux distribution designed to be as high-performing as possible for server and cloud use – it’s the brainchild of Intel, which is positioning it as a key building block for containerized applications in particular and the cloud in general. It features a sophisticated workload scheduler, optimizations to the kernel and major Linux components like systemd and stateless operation.

    Stateless is a big deal, according to Microsoft open source product manager Jose Miguel Parrella, particularly for teams operating in a DevOps environment.

    “By separating the system defaults and distribution best practices from the user configuration, Clear Linux simplifies maintenance and deployment which becomes very important as infrastructure scales,” he said in a statement.

    Microsoft’s embrace of Linux as a technology of the future, particularly where the cloud is concerned, has been well-documented. The company, which joined the Linux Foundation in November, says that fully a third of all virtual machines running on Azure are Linux.

    The Next Great Linux Distro For Gaming?

    Looks like a SteamOS alternative in the making

    Currently focused on workstation and server performance, Intel’s Clear Linux distribution already ships with latest Mesa stack. While Clear Linux doesn’t offer dedicated graphics support, it can surely help one build a good Steam gaming box with Intel hardware.

    A couple of years ago, whenever someone talked about gaming on PC, I imagined a Windows-based system with tons of RAM and high-end graphics. If you’re an open source and Linux enthusiasts, I don’t think I need to give any explanation.

    But, today, the overall picture is changing. Due to the combined efforts of hardware makers, Linux kernel devs, and gaming studios, more and more games are being released on Linux. In 2016 alone, 1,000+ games were released on Steam with Linux support.

    For past couple of years, Intel’s Open Source Technology Center has been working on its Clear Linux distro to bring the best Linux support for Intel hardware in cloud-based deployments. While Clear Linux is mostly focused on workstation/server performance, its developers are working to bring the support for Steam.

    As spotted by Phoronix, Intel developer Arjan van de Ven has tweeted a picture that shows Steam running on Clear Linux:

    Clear Linux already ships with latest Mesa stack, which includes Vulkan drivers. Recently, it also added a games bundle. As this Linux distro is fine tuned for performance on Intel hardware, it’ll be interesting to try out gaming on Clear Linux in future.

    However, at the moment, Clear Linux only offers accelerated graphics, and the open source Radeon or NVIDIA proprietary drivers don’t work. As a result, Clear Linux can become a good contender to play Steam OpenGL/Vulkan games that don’t ship with high-end graphics.

    In the near future, I hope that Clear Linux also ships with support for dedicated graphics and becomes a gaming Linux distro in the true sense.

    6 key points about Intel's hot new Linux distro

    Intel’s container-focused Linux distro for the cloud is packed with intriguing features. Here’s what you need to know

    Serdar Yegulalp

    The great thing about Linux is is that anyone possessing the wherewithal and dedication can produce a distribution to satisfy their own needs. That's also the bad thing, as it means many Linux distributions, even those with name backing, fight to distinguish themselves or to be recognized at all.

    With Intel Clear Linux, the name-brand recognition is only a small part of what matters. Yes, it's significant that the kingpin chipmaker is adding an entry to Linux Distro Makers Club, but why and to what end?

    1. It's all about performance -- on Intel's hardware

    Intel wants Clear Linux to be known for high performance when running cloud workloads. This works not only by using the latest and greatest Linux innovations -- although they are in play -- but also by incorporating features only available in recent-generation Intel processors.

    For most people, this won't be a practical barrier. Nearly anyone with ambitions to run Linux at scale will do so on an Intel Core processor (at least fourth generation) or an Intel Xeon E5 v3 or E3 v5. What might give some people pause: This ties any performance advantages afforded by Clear Linux specifically to Intel hardware. In other words, it's more a philosophical than a practical concern, but you should keep it in mind if you're uneasy about committing to one manufacturer's processor architecture.

    2. It's also all about containers

    Aside from the performance improvements, Intel's vision is to create a "lean and fast" (Intel's own words) distribution to run container workloads in the cloud. This should sound familiar -- folks like CoreOS have been doing the same with their Linux distributions.

    Intel brings to the table the above-mentioned performance improvements, specifically to run containers and equip them with better security with hardware-level VM-style isolation. Intel has brought in several optimizations, like placing certain parts of the filesystem in persistent memory to allow fast booting of kernels in the KVM hypervisor. This means slightly slower startup times than with Docker, but Intel believes the trade-off of startup time versus performance will be more than worth it.

    3. It's for people who hate updates

    Another point of comparison with CoreOS is Clear Linux's construction as an OS. Most of the recent wave of Linuxes employ new approaches to packaging, delivering, and maintaining the OS -- for example, Project Atomic from Red Hat, which uses containers.

    Clear Linux is a different embodiment of the same underlying philosophy: Make the system easy to update, maintain, and roll back, whatever the mechanism. With updates, for instance, Clear Linux eschews the idea of individual package updates. Instead, each change set is delivered as a single systemwide update that applies only the needed changes to the system based on whichever version is currently running. Intel claims this method reduces the amount of state information that has to be tracked for a given OS version to a single number.

    4. Its benchmarks are impressive

    People have good reason to be suspicious of benchmarks: They often reflect the construction of a test more than they reflect performance. But they also provide a hint as to where an item falls within a spectrum of choice.

    Michael Larabel of Linux enthusiast site Phoronix benchmarked Clear Linux in November 2016 against several container-oriented distributions: Ubuntu 16.10, CentOS 7, Debian 8, and Alpine Linux 3.4.4. Clear Linux was modestly faster in many respects and markedly faster in others. Caffe, a deep learning framework, ran far faster on Clear Linux than Debian or Ubuntu; Clear Linux also edged out the competitor with Redis. On the other hand, a bare-metal host -- a logical choice for high performance -- still beat the pants off everything else in compilation and edged out the others on PostgreSQL.

    5. Its best ideas seem as yet untapped

    Several of Clear Linux's most touted features seem like solutions waiting for problems to happen to them, or for real-world use cases to prove how much of a draw they really are. Function multiversioning (FVM), for instance, allows C code to support multiple versions of the same function in a single binary, with the different versions optimized for different sets of processor extensions. As a result, a single binary could be produced that exploits specific processor features if they're available and falls back to a safe default if they aren't.

    The idea is to "write once and deploy everywhere," and to allow the user to have to obtain only a single binary for optimal performance. But the use cases for this seem fairly narrow -- nice to have, but not essential.

    More appealing and more immediately useful are what Intel bills as "stateless" features in the distribution -- specifically, keeping distribution data and administrator-defined data separate. Removing /etc and /var in a Clear Linux distribution "effectively performs a factory reset." This allows the system to be more readily configured for specific functions with less hassle -- a devops win, in theory. We'll want to see how that plays out for regular Joe Admins.

    6. Microsoft takes it seriously

    Clear Linux is now one of the support Linux distributions available to run on Microsoft Azure, as revealed last week. Given the historically close relationship between Microsoft and Intel, it would've been downright embarrassing for Microsoft to let another cloud provider offer Clear Linux support first.

    Three versions of Clear Linux -- a bare-bones VM, one that's Docker-centric, and one outfitted with machine learning tools -- are available for immediate use. The last one in particular makes sense in light of Phoronix's benchmarks, and in turn hints at how Clear Linux might find its audience by running specific loads both faster and more conveniently than the competition.
