OSS

Deployments of OpenStack cloud are growing faster in China and the APAC region than anywhere else in the world, backed in part by the Chinese government's vocal support for the open source infrastructure.

It is China in particular where some of the biggest deployments are running. China UnionPay recently overtook Visa for the largest volume of card payments in the world. The state-operated railway network China Rail oversees billions of passengers every year. By total number of subscribers China Mobile tops the list for biggest mobile phone operator globally. And the massive utility organisation the State Grid Corporation of China employs 1.5 million people.

All of these enormous enterprises are running OpenStack clouds. Why?

A server is a computer software or a machine that offers services to other programs or devices, referred to as “clients“. There are different types of servers: web servers, database servers, application servers, cloud computing servers, file servers, mail servers, DNS servers and much more.

The usage share for Unix-like operating systems has over the years greatly improved, predominantly on servers, with Linux distributions at the forefront. Today a bigger percentage of servers on the Internet and data centers around the world are running a Linux-based operating system.

  • China moves ahead of US on Top 500 supercomputer list; Linux now found on every machine

    The bi-annual Top 500 supercomputer list has reached its fiftieth edition, bringing with it two important milestones: China has more machines on the list than the US, and every computer now runs Linux.

    Boasting 202 entries, China can now claim more supercomputers in the top 500 than ever before. At the same time, the US has its lowest number of places—144—since the list began 25 years ago. Back in June, China took 159 spots while the US led with 169.

  • It took 19 years, but Linux finally dominates an entire market

    LINUX MAY well still be viewed as the preserve of 'hobbyists', but there's one category of devices in which Linux rules the market: supercomputers. 

    According to ZDNet, it's the first time that Linux systems have taken all 500 spots in the TOP500 Supercomputer list - with the last two non-Linux supercomputers dropping off between the lists released in June and November of this year.

  • Linux Now Powers 100% of the World’s Top 500 Supercomputers

    Linux now powers 100% of the world’s 500 fastest supercomputers. That’s according to the latest stats out from supercomputer hawks TOP500, who post a biannual list of the world’s most powerful commercially available computer systems. Linux has long dominated the TOP500 list, powering the majority of the machines that make it.

  • IT disaster recovery: Sysadmins vs. natural disasters

    In terms of natural disasters, 2017 has been one heck of a year. Hurricanes Harvey, Irma, and Maria brought destruction to Houston, Puerto Rico, Florida, and the Caribbean. On top of that, wildfires burned out homes and businesses in the West.

    It’d be easy to respond with yet another finger-wagging article about preparing for disasters—and surely it’s all good advice—but that doesn’t help a network administrator cope with the soggy mess. Most of those well-meant suggestions also assume that the powers that be are cheerfully willing to invest money in implementing them.

  • OCI Update: v1.0.1 Release and New Maintainer

    The OCI community continues to be hard at work, having just issued the first update to OCI v.1.0, after five months of focusing on stability. OCI 1.0.1 contains updates to both the image format and runtime specifications.

    We’re still growing and expanding, with even more collaboration since the launch of v 1.0. For example, we are now up to over 5,000 commits from 184 authors across 42 different organizations. Organizations like AWS, Docker, Cloud Foundry, CoreOS, Intel, Mesosphere, Oracle, Red Hat and Kubernetes have already taken advantage of the OCI v1.0 specifications, and with v1.0.1 now available, the industry is on the precipice of true portability and standardization. We had a strong showing on site at recent industry events, at both DockerCon Europe in Copenhagen and Open Source Summit Europe in Prague.

  • How enterprise IT uses Kubernetes to tame container complexity

    Running a few standalone containers for development purposes won’t rob your IT team of time or patience: A standards-based container runtime by itself will do the job. But once you scale to a production environment and multiple applications spanning many containers, it’s clear that you need a way to coordinate those containers to deliver the individual services. As containers accumulate, complexity grows. Eventually, you need to take a step back and group containers along with the coordinated services they need, such as networking, security, and telemetry.

    That’s why technologies like the open source Kubernetes project are such a big part of the container scene.

  • Orange and Red Hat push open source NFVi development

    At the OpenStack Summit 2017, operator Orange has joined forces with equally colourful open-source software vendor Red Hat to promote NFVi innovation.

    Sadly the two companies have missed a trick by declining to name their mutual endeavour Orange Hat, but we mustn’t let that detract from the underlying cleverness. Orange seems to reckon network functions virtualization infrastructure is best done in the open-source environment and Red Hat unsurprisingly agrees.

  • MongoDB 3.6 runs at the 'speed of data'

    MongoDB 3.6 will be generally available in early December.

    The open source (at its core) general purpose database has some noteable changes (its makers would call them enhancements) including a so-called ‘change streams’ feature, which enable developers to build what are being described as more ‘reactive’ web, mobile and IoT applications that can view, filter and act on data changes as they occur in the database.

  • I wrote a Web Component

    I’ve been meaning to play with Web Components for a little while now. After I saw Ben Nadel create a Twitter tweet progress indicator with Angular and Lucas Leandro did the same with Vue.js I thought, here’s a chance to experiment.

    Web Components involve a whole bunch of different dovetailing specs; HTML imports, custom elements, shadow DOM, HTML templates. I didn’t want to have to use the HTML template and import stuff if I could avoid it, and pleasantly you actually don’t need it. Essentially, you can create a custom element named whatever-you-want and then just add content here elements to your page, and it all works. This is good.

  • PHP 7.2.0RC6 Released

    The PHP development team announces the immediate availability of PHP 7.2.0 RC6. This release is the sixth Release Candidate for 7.2.0. Barring any surprises, we expect this to be the FINAL release candidate, with Nov 30th's GA release being not-substantially different. All users of PHP are encouraged to test this version carefully, and report any bugs and incompatibilities in the bug tracking system.

  • What is OpenHPC?

    High performance computing (HPC)—the aggregation of computers into clusters to increase computing speed and power—relies heavily on the software that connects and manages the various nodes in the cluster. Linux is the dominant HPC operating system, and many HPC sites expand upon the operating system's capabilities with different scientific applications, libraries, and other tools.

    As HPC began developing, that there was considerable duplication and redundancy among the HPC sites compiling HPC software became apparent, and sometimes dependencies between the different software components made installations cumbersome. The OpenHPC project was created in response to these issues. OpenHPC is a community-based effort to solve common tasks in HPC environments by providing documentation and building blocks that can be combined by HPC sites according to their needs. 

  • Containerd Brings More Container Runtime Options for Kubernetes

    A container runtime is software that executes containers and manages container images on a node. Today, the most widely known container runtime is Docker, but there are other container runtimes in the ecosystem, such as rkt, containerd, and lxd. Docker is by far the most common container runtime used in production Kubernetes environments, but Docker’s smaller offspring, containerd, may prove to be a better option. This post describes using containerd with Kubernetes.

  • Prometheus 2.0 Arrives with a Speedy New Local Storage Engine

    Improved local storage is at the heart of the new release of Prometheus 2.0, according to Fabian Reinartz, a CoreOS software engineer and a core developer of the Prometheus monitoring system.

    With distributed system coordination software such as Kubernetes and Mesos, monitored environments have become increasingly more dynamic, Reinartz pointed out in a blog post. The motioning software needed its own dedicated storage to ensure responsiveness in these dynamic environments.

    Though Prometheus 1.6 introduced auto-tuning capabilities, the team has been working on a more performant time-series database. “It’s just way more reliable and faster. Ideally, you don’t want to have to reconfigure all the time, so Prometheus just responds to change in demands, so there are way fewer knobs to turn for the people running it,” Reinartz said in an interview.
