  • Containers running Containers

    Some genuinely exciting news piqued my interest at this year’s DockerCon, that being the new Operating System (OS), LinuxKit, which was announced and is immediately on offer from the undisputed heavyweight container company, Docker.

    The behemoth has announced a flexible, extensible Operating System where system services run inside containers for portability. You might be surprised to hear that even includes the Docker runtime daemon itself.

    [...]

    As the powerhouse that is Docker continues to grow arms and legs there’s no doubt whatsoever that these giant-sized leaps in the direction of solid progress will benefit users and other software projects alike.

  • Bare-metal Kubernetes

    A few years ago, I attended my first Linux conference, DevConf 2014. Many of the speakers talked about containers and how wonderful they were, and my interest was piqued, but I’ve never really had an opportunity to use them.

    As the sysadmin for a school, there just isn’t much need for the scalability provided for by containers. Our internal web site runs on a single VM, and the short downtimes required for system updates and upgrades are not a problem, especially if I plan them for the weekends. On the flip side, having something that we can use to spin up web services quickly isn’t a bad idea, so, over the last few months, I’ve been experimenting with Kubernetes.

OpenStack and Cloudera

  • OpenStack User Survey Indicates Growth in Most Sectors

    A look at the numbers released last week by the OpenStack Foundation from its ninth user survey should be of interest to anyone considering the platform as part of a cloud solution. The platform's percentage of the overall cloud market remains level, at about two-thirds of the total clouds in deployment. That in itself represents a large increase in total deployments, as cloud use continues to rise. Add to that a rapid increase in proof-of-concept and test use, and it's clear that OpenStack's place in the cloud continues to strengthen.

  • 4 types of OpenStack Neutron networks you must understand

    If your OpenStack hosted virtual instances need network connectivity you’re going to have to create a network. There are multiple kinds of networks and in order to make the right choice you will need to understand at least two very important network attributes: ‘router:external’ and ‘shared.’ Unless you know what these attributes and their combinations mean, it will be difficult to make the optimal network choice.

  • Cloudera’s IPO is overshadowed by a rival it won’t mention

    One of the original poster children of the big data software craze, Cloudera, is due for its long-awaited IPO this week. Sometime Thursday afternoon, its shares will price somewhere between $12 and $14 and will open for trading on the New York Stock Exchange the following morning, raising about $200 million in the process.

    Make no mistake, this IPO qualifies as what’s known in venture capital circles as a down round. Essentially the new investors are buying shares in a company that is worth less than it was during its prior funding rounds.

  • Certified Ubuntu Images available on Oracle Bare Metal Cloud Service

    Certified Ubuntu images are now available in the Oracle Bare Metal Cloud Services, providing developers with compute options ranging from single to 16 OCPU virtual machines (VMs) to high-performance, dedicated bare metal compute instances. This is in addition to the image already offered on Oracle Compute Cloud Service and maintains the ability for enterprises to add Canonical-backed Ubuntu Advantage Support and Systems Management. Oracle and Canonical customers now have access to the latest Ubuntu features, compliance accreditations and security updates.

  • Canonical's Certified Ubuntu Images Land in Oracle's Bare Metal Cloud Service

    Canonical announced the official availability of Certified Ubuntu images in Oracle's Bare Metal Cloud Services, which accompany the images that the company already provides in the Oracle Compute Cloud Service.

    Canonical's Certified Ubuntu images in Oracle Bare Metal Cloud Services are a great addition because they promise to provide developers with dedicated, high-performance bare-metal compute instances, as well as virtual machines with up to 16 Oracle Compute Unit (OCPU). They also add the ability for Oracle's enterprise customers to access the latest and greatest Ubuntu features.

  • How Kubernetes is making contributing easy

    As the program manager of the Kubernetes community at Google, Sarah Novotny has years of experience in open source communities including MySQL and NGINX. Sarah sat down with me at CloudNativeCon in Berlin at the end of March to discuss both the Kubernetes community and open source communities more broadly.

    Among the topics we covered in the podcast were the challenges inherent in shifting from a company-led project to a community-led one, principles that can lead to more successful communities, and how to structure decision-making.

  • How Microsoft helped Docker with LinuxKit and Moby Project [Ed: Microsoft 'helped'... embrace, extend, coerce; haven't Docker employees learned from history?]

    Today, supporting Linux is as critical to Microsoft as it is to Red Hat and SUSE.

  • How to make branding decisions in an open community

    On April 18, Docker founder Solomon Hykes made a big announcement via a pull request in the main Docker repo: "Docker is transitioning all of its open source collaborations to the Moby project going forward." The docker/docker repo now redirects to moby/moby, and Solomon's pull request updates the README and logo for the project to match.

    Reaction from the Docker community has been overwhelmingly negative. As of this writing, the Moby pull request has garnered 7 upvotes and 110 downvotes on GitHub. The Docker community is understandably frustrated by this opaque announcement of a fait accompli, an important decision that a hidden inner circle made behind closed doors. It's a textbook case of "Why wasn't I consulted?"

Ubuntu developers today have announced a "tech preview" of their new text-based installer for Ubuntu Server.

Earlier this month we heard of a new Ubuntu Server installer being worked on and it was dubbed Subiquity. Now that the 17.04 release has cleared and 17.10 development begun, the new installer was announced as a tech preview for Ubuntu Server 17.04.

Mathieu Trudel-Lapierre announced, "During the 17.04 development cycle, the Ubuntu Foundations team has been working on a new experimental installer for servers. We are now ready to get feedback from a wider audience."

The new replication features in MySQL 8

Filed under
Server
OSS

This year at the Percona Live open source database conference, I will present a talk on the latest replication features in MySQL 8.0.

It was a huge amount of work to get the MySQL Group Replication plugin out with MySQL 5.7.17. Group Replication is a new plugin that gives the user some nice replication properties by resorting to group communication and state machine replication. This makes the system able to protect data against split brain situations, enables fault-tolerance and high availability, and provides coordination between servers committing transactions that change the data.

In addition to Group Replication, the team has also invested quite a bit on core replication features. Some of these features were already released, and others will be released at some point in time in a MySQL Development Milestone Release (DMR).

  • Open for business: Hortonworks aims for open source profitability

    It used to be the Hadoop Summit, but the strategic focus at Hortonworks the enterprise-ready open source Apache Hadoop provider, has evolved. So, this year it was renamed DataWorks Summit. The company now encompasses data at rest (the Hadoop Data Platform now in version 2.6), data in motion (the Hadoop Data Flow) and data in the cloud (the Hadoop Data Cloud). Hortonworks aims to become a multi-platform and multi-cloud company. The focus is on the data in data driven organisations. Just a few years ago Hortonworks connected with IT architects. Today it’s launching conversations with lines of business and chief marketing officers.

  • Make your own NES Classic Edition with Lakka 2.0 LibreELEC Linux distro and Raspberry Pi
    The NES Classic Edition is a very fun nostalgia-based gaming console. As someone who grew up with Nintendo, I knew I wanted the mini system as soon as it was announced. A family member was able to score me one on launch day, and I've been very happy with it. Unfortunately, other people have not been so lucky. Supply was very limited and it has since been discontinued. If you do not already have it, you are sort of out of luck without paying high prices on eBay or Craigslist. If you are only looking to replay the NES games of your youth, and you are OK with doing it in an unofficial way, emulation is another route. In fact, if you'd rather not play these games on your PC, you can instead use a Linux-based operating system and a Raspberry Pi (or other devices) hooked to a television. One such distro is Lakka, which just reached version 2.0. It is arguably better than an NES Classic Edition as it can also play games from other systems, such as SNES, Sega Genesis, Nintendo 64, PlayStation 1, and many more.
