  • Navigating Kubernetes and edge computing

    Often the best path to working with two vanguard technologies is unclear. That’s why OpenDev, a recent two-day event sponsored by the Ericsson, Intel and the OpenStack Foundation, dedicated a session to folks navigating Kubernetes and edge computing. Both technologies appear to be here to stay. “Containers are what the developers are using,” said Jeremy Huylebroeck of Orange Silicon Valley. “It’s way more convenient for them to actually publish their code and try things faster.”

    OpenDev was devised as more of a workshop than a traditional conference, you can also check the event schedule for Etherpads from the individual sessions.

  • ​Kubernetes takes a big step forward with version 1.8

    If you want to manage containers in the cloud, Kubernetes is the program for you. Its latest release, Kubernetes 1.8, is better than ever.

    Enterprise Linux vendor SUSE is updating a number of different platforms this week, including its Kubernetes based CaaS Platform.

Stealth Lobbying Campaign Blamed Elizabeth Warren For 'Socialist Plot' She Had Nothing To Do With

OSS

Oracle, the California-based software company, appears to be behind the lobbying campaign using Warren as its foil. The campaign targeted Warren as the supposed source of a provision added to the National Defense Authorization Act that would encourage the Department of Defense to use open-source software for non-battlefield purposes.

“Open-source software” refers to computer programs for which the source code is both transparent and available for use and reuse by anyone, for any purpose, under the conditions defined by a given license. This is different from the proprietary software often purchased by government agencies, where the agency does not have access to the source code.

For proprietary software, the agency must go back to the company that sold the software and pay for any upgrade, update, patch or fix needed to maintain continued operations. The proprietary model often means that one company has a monopoly on knowledge of military and government systems.

  • Microservices and containers: 5 pitfalls to avoid

    Because microservices and containers are a match made in heaven, it might seem like nothing could go wrong. Let’s get these babies into production as quickly as possible, then kick back and wait for the IT promotions and raises to start flooding in. Right?

    (We’ll pause while the laughter subsides.)

    Yeah, sorry. That’s just not how it works. While the two technologies can be a powerful combination, realizing their potential doesn’t happen without some effort and planning. In previous posts, we’ve tackled what you should know at the start. But what about the most common problems organizations encounter when they run microservices in containers?

  • This Week in Numbers: Container Storage Preferences for Kubernetes

    The types of logical storage structures used in today’s Kubernetes deployments offer some deeper revelations into the nature of workloads being deployed. Block storage is king, having been cited by two-thirds (66 percent) of respondents in our survey for The State of the Kubernetes Ecosystem as being involved with their Kubernetes implementations.

    Few deployments are relegated to only one type of logical storage, so it is telling that just fewer than half of the respondents (46 percent) cited file storage as the type they’re using. Newer, cloud-native applications with microservices architectures and that utilize databases or data structures, typically don’t need a file system because they are not interacting with data through an operating system. A 46 percent figure is quite high, signaling that more integration with older application types is taking place.

    Object storage is used by 29 percent of respondents, which is relatively high compared with adoption rates for object storage that we’ve seen in the past. Since object storage is scalable, developers working on distributed systems likely have experience with it already. In addition, object storage is often used to deliver static content for websites, which is also a common type of workload for Kubernetes.

  • Patch CDK #1: Build & Release

  • ​SUSE Studio merges with Open Build Service

    When SUSE first introduced SUSE Studio in 2010, it was a radical change. You could build your own Linux distribution without being a Linux expert. Today, we use custom Linux images inside containers, virtual machines (VM), and every cloud worth its name every day. So SUSE is updating SUSE Studio by merging it with its Open Build Service (OBS) to create a better tool for bundling packages with Linux distributions to deliver customized Linux images. The new product's name will be SUSE Studio Express.

  • When Microsoft met SUSE: This Windows-Linux partnership gets stronger every day [Ed: "Linux purists hated that partnership". Not Linux. Not purists. GNU. And people who value freedom.]

    Linux purists hated that partnership. But my, how things have changed! Today, Microsoft has joined The Linux Foundation; all the major Linux distributions, including Debian and Red Hat are available on Microsoft's Azure cloud; and Microsoft recently joined the Open Source Initiative.

  • GNU Emacs: A Great Text Editor For Ubuntu/Linux Mint

    Emacs text editor doesn't need any introduction because it is quite famous and used widely. Emacs is a free, open-source, extensible, customizable text editor. It is cross-platform available for Linux, Windows and Mac, developed by GNU project and released under GNU GPL license. Development of the first Emacs began in the mid-1970s, and work on its direct descendent, GNU Emacs, continues actively as of 2017. Richard Stallman began work on GNU Emacs in 1984 to produce a free software alternative to the proprietary Gosling Emacs.
    Emacs has over 10,000 built-in commands and its user interface allows the user to combine these commands into macros to automate work. Additionally, implementations of Emacs typically feature a dialect of the Lisp programming language that provides a deep extension capability, allowing users and developers to write new commands and applications for the editor. Extensions have been written to manage email, files, outlines, and RSS feeds, as well as clones of ELIZA, Pong, Conway's Life, Snake and Tetris.

  • HHVM 3.22

    HHVM 3.22 is released! This release primarily contains bug fixes, performance improvements, and supporting work for future improvements. Packages have been published in the usual places; see the installation instructions for more information.

    HHVM 3.22 is now available as this alternative PHP implementation and what serves as the basis for Facebook's Hack programming language.

    While HHVM 3.22 supports PHP5/PHP7, keep in mind Facebook recently announced they are eventually abandoning their PHP focus in favor of focusing HHVM on their Hack language. HHVM 3.24 will be the last release focusing on PHP compatibility while support may still work beyond that for some time, but Hack is Facebook's focus.

  • Container Linux by CoreOS

    Container Linux by CoreOS, originally named CoreOS Linux, is an open source operating system (OS) that provides the functionality required to deploy and manage applications within containers. Based on the Linux kernel, Container Linux by CoreOS is designed for massive scale, with management features to ensure minimal operational overhead.

  • The Role of API Gateways in Microservice Architectures

    Despite their differences in nomenclature, newly emerging service meshes aren’t all that different that API Gateways, and the similarities between the two will continue to grow over time, so predicts Marco Palladino, Chief Technology Officer of API Gateway provider Mashape.

    The two technologies actually offer quite similar functionality, Palladino noted. API Gateways, such as Amazon Web Services‘ API Gateway or Mashape’s own open source Kong, have been primarily used over the last decade or so for mapping external traffic to internal resources, whereas the more recently developed service meshes — such as Lyft’s Envoy or Uber’s Catylist— have been primarily been on brokering internal resources in a microservices architecture.

  • Microservice architecture takes a whole new approach to infrastructure

    With services like Netflix, Uber, YouTube, and Facebook, most people are used to apps that respond quickly, work efficiently, and are updated regularly. Patience is no longer a virtue, and thanks to apps like the ones mentioned above, when people use applications, they expect blistering speeds and uninterrupted service. If you do not provide that, users aren’t exactly starved for choice; it takes less than a minute to delete an app and download something else as a replacement.

  • Clear Linux Project Announces the Next Generation of Intel's Clear Containers

    Intel's Clear Linux and Clear Containers teams are happy to introduce the next-generation of Intel's Clear Containers project, version 3.0, which bring many important new features and performance improvements.

    Rewritten in the Go language, Intel Clear Containers 3.0 introduces support for leveraging code used for namespace-based containers and better integrates into the container ecosystem, allowing support for Docker container engine and Kubernetes. It also improves the compatibility with the POSIX family of standards.

    "Today’s release presents a generational and architectural shift to utilize virtcontainers, a modular and hypervisor agnostic library for hardware virtualized containers. Clear Containers 3.0 is written in Go language and boasts an OCI compatible runtime implementation (cc-runtime) that works both on top of virtcontainers, and as a platform for deployment," said Amy L Leeland, Technical Program Manager, Intel Corporation.

  • “Spaceborne” Linux Supercomputer Starts Running In Space, Achieves 1 Teraflop Speed

    About one month ago, the HPE’s Spaceborne Computer was launched into the space using SpaceX Dragon Spacecraft. This beast was launched as a result of a partnership between Hewlett Packard Enterprise (HPE) and NASA to find out how high-performance computers perform in space. Now, this supercomputer is fully installed and operational in ISS.

    The performance experiment will be carried out for one year, which is roughly the time it will take for a spacecraft to travel to Mars. At the moment, lots of calculations for space research projects are carried out on Earth, but this brings in an unavoidable factor of latency.

  • Kubernetes Snaps: The Quick Version

    When we built the Canonical Distribution of Kubernetes (CDK), one of our goals was to provide snap packages for the various Kubernetes clients and services: kubectl, kube-apiserver, kubelet, etc.

    While we mainly built the snaps for use in CDK, they are freely available to use for other purposes as well. Let’s have a quick look at how to install and configure the Kubernetes snaps directly.

  • Kubernetes is Transforming Operations in the Enterprise

    At many organizations, managing containerized applications at scale is the order of the day (or soon will be). And few open source projects are having the impact in this arena that Kubernetes is.

    Above all, Kubernetes is ushering in “operations transformation” and helping organizations make the transition to cloud-native computing, says Craig McLuckie co-founder and CEO of Heptio and a co-founder of Kubernetes at Google, in a recent free webinar, ‘Getting to Know Kubernetes.’ Kubernetes was created at Google, which donated the open source project to the Cloud Native Computing Foundation.

  • Kubernetes gains momentum as big-name vendors flock to Cloud Native Computing Foundation

    Like a train gaining speed as it leaves the station, the Cloud Native Computing Foundation is quickly gathering momentum, attracting some of the biggest names in tech. In the last month and a half alone AWS, Oracle, Microsoft, VMware and Pivotal have all joined.

    It’s not every day you see this group of companies agree on anything, but as Kubernetes has developed into an essential industry tool, each of these companies sees it as a necessity to join the CNCF and support its mission. This is partly driven by customer demand and partly by the desire to simply have a say in how Kubernetes and other related cloud-native technologies are developed.

  • The Cloud-Native Architecture: One Stack, Many Options

    As the chief technology officer of a company specialized in cloud native storage, I have a first hand view of the massive transformation happening right now in enterprise IT. In short, two things are happening in parallel right now that make it radically simpler to build, deploy and run sophisticated applications.

    The first is the move to the cloud. This topic has been discussed so much that I won’t try to add anything new. We all know it’s happening, and we all know that its impact is huge.

  • Sysadmin 101: Leveling Up

    I hope this description of levels in systems administration has been helpful as you plan your own career.

I hope this series in Sysadmin 101 fundamentals has been helpful for those of you new to the sysadmin trenches, and also I hope it helps save you from having to learn from your own mistakes as you move forward in your career.
