  • Future Proof Your SysAdmin Career: Looking to the Cloud

    Sysadmins will always need core competencies such as networking and security, but increasingly, they can differentiate themselves by mastering new platforms and tools. Previously in this series, we've provided an overview of essentials, evolving network skills, and security. In this article, we'll look at how experience with open cloud computing platforms such as OpenStack can make a difference in your sysadmin career.

  • Top 5 container mistakes that cause security problems

    Given that many companies are still wrapping their arms around the potential of container technology and how to best leverage it, there is still a lot of experimentation with containers.

    Developers are working in their own sandboxes, setting them up on their laptops and then putting them into production. The issue, though, is that if containers are done without security measures in mind, you may not have the agility you want with the right controls.

    As a result, unknown content can end up in containers, even with today's growing marketing container tools. Kristen Newcomer, security strategist at RedHat, says before putting containers into production, you need to ask, "What’s the right process to manage this? How do I make sure things are controlled and managed as I would any other application?"

  • Time, Security Cited as Hurdles to Adoption of Containers

    Containers remain a nascent cloud platform choice for many enterprises. But lack of ecosystem maturity and familiarity are seen as early-stage hurdles toward adoption.

    Dustin Kirkland, VP of product at Canonical who’s on the company’s Ubuntu products and strategy team, said one of the biggest issues facing container adoption today is simply time. Containers are still relatively new in the eyes of enterprise customers who have only recently come to understand the benefits of virtual machines (VMs).

  • 4 container adoption patterns: What you need to know

    At this time of digital transformation, it’s crystal clear why today’s businesses desire speed. When a rival uses technology to make an unexpected move, or makes a big acquisition, you must react quickly. For example, the recent Amazon acquisition of Whole Foods demands fast action from supermarket competitors. To achieve that kind of business speed, IT leaders want to flip the 80/20 paradigm, where IT traditionally spent 80 percent of its budget on maintenance and 20 percent on innovation. CIOs seek to allocate more budget to help the business be agile and nimble.

Open Source Leaders: Solomon Hykes and the Docker Revolution

Filed under
Server
Interviews
OSS

Not often we come across technologies that are so disruptive that they turn industries upside down. Docker container is one such technology that’s literally transforming the IT world. Docker founder and Chief Technology Officer Solomon Hykes is one of the few technology leaders who thoroughly understands the open source development model and the sauce that’s needed to turn into a profitable business.

Hykes may not sound very French, but he grew up in France. His parents moved there when he was very young. Hykes began programming as a teenager. Throughout most of high school, he skipped classes to work on programming jobs at the local cyber café. Eventually, he went to a programming school for software engineering training.

OSS

Business software company Docker Inc. is raising fresh funds, valuing the company at $1.3 billion, according to people familiar with the matter.

The latest influx of $75 million, which is expected to close by the end of the month, will help fuel Docker’s newest push to win business customers and finally monetize its free open-source tools popular with developers worldwide. Part of the funding will go toward building a sales and marketing team for corporate clients, one of the people said, asking not to be identified discussing private matters. The valuation would represent a marginal increase from the $1 billion it was ascribed when it last raised money in 2015.

  • Red Hat updates OpenShift container platform with new service catalog

    Red Hat issued its quarterly update to the OpenShift platform today, adding among other things, a Service Catalog that enables IT or third-party vendors to create connections to internal or external services.

    OpenShift is RedHat’s Platform as a Service, based on Kubernetes, the open source container management platform, which was originally developed by Google. It also supports Docker, a popular container platform, and adheres to the Open Container Initiative, a set of industry standards for containers, according to the company.

    As companies make the shift from virtual machines to containers, there is an increasing need for platforms like OpenShift, and Red Hat is seeing massive interest from companies as varying as Deutsche Bank, Volvo and United Health.

  • 3 open source projects that make Kubernetes easier

    Clearly, Kubernetes is an elegant solution to an important problem. Kubernetes allows us to run containerized applications at scale without drowning in the details of balancing loads, networking containers, ensuring high availability for apps, or managing updates or rollbacks. So much complexity is hidden safely away. 

    But using Kubernetes is not without its challenges. Getting up and running with Kubernetes takes some work, and many of the management and maintenance tasks around Kubernetes are downright thorny. 

    As active as Kubernetes development is, we can’t expect the main project to solve every problem immediately. Fortunately, the community around Kubernetes is finding solutions to those problems that, for one reason or another, the Kubernetes team hasn’t zeroed in on.

DevOps and Service Mesh

  • DevOps Fundamentals, Part 5: Consistency in the Pipeline
  • Pattern: Service Mesh

    Since their first introduction many decades ago, we learnt that distributed systems enable use cases we couldn’t even think about before them, but they also introduce all sorts of new issues.

    When these systems were rare and simple, engineers dealt with the added complexity by minimising the number of remote interactions. The safest way to handle distribution has been to avoid it as much as possible, even if that meant duplicated logic and data across various systems.

    But our needs as an industry pushed us even further, from a few larger central computers to hundreds and thousands of small services. In this new world, we’ve had to start taking our head out of the sand and tackling the new challenges and open questions, first with ad-hoc solutions done in a case-by-case manner and subsequently with something more sophisticated. As it often happens with technology, we have first found ad-hoc solutions in a case-by-case manner. As we find out more about the problem domain and design better solutions, we start crystallising some of the most common needs into patterns, libraries, and eventually platforms.

  • What is Photon OS, and why would I use it in my data center?

    The Photon OS was designed to provide a lightweight, open source Linux container host runtime optimized for VMware platforms, including vSphere 5.5, vSphere 6, vCloud Air, VMware Fusion and VMware Workstation Pro. In effect, vSphere users can employ Photon to use containers most efficiently in VMware environments. The Photon OS runtime is compatible with other container formats, including Docker, Rkt and Garden runtimes. For example, Photon allows you to migrate and run containers already developed and deployed on Docker platforms in vSphere environments.

  • PiCluster v2.0 brings better container management for Docker deployments

    Linux Toys has announced PiCluster 2.0. The new version of the open source container management tool is written in Node.js and is designed to deliver an upgraded experience through cleaner CSS and JQuery dialogue windows.

    The new version of PiCluster brings automatic container failover to different hosts. It fixes reported errors in npm build dependency as well as utilises enhancements on the CSS front to deliver a fresh look to the web console of the tool. Additionally, users can now deploy container management without Internet access by using the web server to deliver required libraries.

  • Site Reliability Engineer: Don’t fall victim to the bias blind spot

    To ensure websites and applications deliver consistently excellent speed and availability, some organizations are adopting Google’s Site Reliability Engineering (SRE) model. In this model, a Site Reliability Engineer (SRE) – usually someone with both development and IT Ops experience – institutes clear-cut metrics to determine when a website or application is production-ready from a user performance perspective. This helps reduce friction that often exists between the “dev” and “ops” sides of organizations. More specifically, metrics can eliminate the conflict between developers’ desire to “Ship it!” and operations desire to not be paged when they are on-call. If performance thresholds aren’t met, releases cannot move forward.

  • OPNFV’s role in NFV testing and the road to 5G

    OPNFV has emerged as the go-to platform for testing and interoperability assurance for NFV and its many components, a role that is set to becoming more important as the industry transitions towards 5G. As Hewlett Packard Enterprise’s Prodip Sen points out, 5G standardisation is about much more than just faster speeds, but also a key enabler of unprecedented features such as network slicing, which ultimately rely on NFV.

PC-MOS/386 is the latest obsolete operating system to open source on Github

PC-MOS/386 was first announced by The Software Link in 1986 and was released in early 1987. It was capable of working on any x86 computer (though the Intel 80386 was its target market). However, some later chips became incompatible because they didn't have the necessary memory management unit. It had a dedicated following but also contained a couple of design flaws that made it slow and/or expensive to run. Add to that the fact it had a Y2K bug that manifested on 31 July 2012, after which any files created wouldn't work, and it's not surprising that it didn't become the gold standard. The last copyright date listed is 1992, although some users have claimed to be using it far longer. Read more

GIMP, More Awesome Than I Remember

For what seems like decades, GIMP (Graphic Image Manipulation Program) has been the de facto standard image editor for Linux. It works well, has many features, and it even supports scripting. I always have found it a bit clumsy, however, and I preferred using something else for day-to-day work. I recently had the pleasure of sitting at a computer without an image editor though, so I figured I'd give GIMP another try on a non-Linux operating system. See, the last time I tried to use GIMP on OS X, it required non-standard libraries and home-brew adding. Now, if you head over to the GIMP site, you can download a fully native version of GIMP for Windows, OS X and Linux. Read more

Linux 4.14-rc6

So rc6 is delayed, not because of any development problems, but simply because the internet was horribly bad my usual Sunday afternoon time, and I decided not to even try to fight it. And by delaying things, I got a couple more ull requests in from Greg. Yay, I guess? rc6 is a bit larger than I was hoping for, and I'm not sure whether that is a sign that we _will_ need an rc8 after all this release (which wouldn't be horribly surprising), or whether it's simply due to timing. I'm going to leave that open for now, so just know that rc8 _may_ happen. Read more Also: Linux 4.14-rc6 Released: Linux 4.14 Kernel Final In 2~3 Weeks
