  • Solving HPC Conflicts with Containers

    Countless stories, comics, and television shows have driven home two very unpleasant stereotypes: the angry, unhelpful system administrator who can’t wait to say “no!” to a user request, and the clueless, clumsy user always a keystroke away from taking down the entire infrastructure. There is a kernel of truth to them. While both resource providers and resource users may want the same end result — the successful completion of computational tasks — they have conflicting priorities when it comes to achieving it.

  • Kubernetes and the Microservices Hierarchy of Needs

    Devised by psychologist Albert Maslow, the Hierarchy of Needs is a psychological theory to explain human motivation, comprising of multitier model of human needs, often depicted as hierarchical levels within a pyramid. Maslow uses terms such as physiological, safety, belongingness and love, esteem, self-actualization, and self-transcendence to describe the stages that human motivation generally moves through. As human beings, first we need our basic needs satisfied, then the psychological ones, and only then we can think of self esteem and achieving our full potential:

  • Stateful containerized applications with Kubernetes

    To date, almost all of the talk about containers and microservices has been about "stateless" applications. This is entirely understandable because stateless applications are simply easier. However, containers and orchestration have matured to the point where we need to take on the interesting workloads: the stateful ones. That's why two of my talks at SCALE 15x are about databases, containers, and Kubernetes, which is an open source system for automating deployment, scaling, and management of containerized applications.

    Stateless services are applications like web servers, proxies, and application code, which may handle data, but they don't store it. These are easy to think about in an orchestration context because they are simple to deploy and simple to scale. If traffic goes up, you just add more of them and load-balance. More importantly, they are "immutable"; there is very little difference between the upstream container "image" and the running containers in your infrastructure. This means you can also replace them at any time, with little "switching cost" between one container instance and another.

  • 13 Companies Leading the Way with Containers

    As DevOps has grown in popularity, an increasing number of organizations are looking to containerization technology as a way to simplify and streamline application deployment and management. In fact, the RightScale 2017 State of the Cloud Report found that Docker, the leading containerization tool, was the most popular DevOps tool among the companies it surveyed. Forty percent of the enterprises surveyed said that they use Docker, and 30 percent more said they planned to do so in the future.

    The OpenStack Foundation has released Ocata, the 15th iteration of the popular open source cloud platform. The latest release has focused on enhancing core compute and networking services and expanding support for application container technologies.

  • RDO Ocata Released

    The RDO community is pleased to announce the general availability of the RDO build for OpenStack Ocata for RPM-based distributions, CentOS Linux 7 and Red Hat Enterprise Linux. RDO is suitable for building private, public, and hybrid clouds. Ocata is the 15th release from the OpenStack project, which is the work of more than 2500 contributors from around the world (source).

  • Walmart Boasts 213,000 Cores on OpenStack

    Two Walmart associates who spoke recently at the Linux Foundation’s Leadership Summit provided some updates on the retailer’s efforts to automate its business.

    According to Andrew Mitry, a distinguished engineer, Cloud, and Megan Rossetti, a senior engineer, Cloud, the company is expanding its cloud services to encompass more than its e-commerce business. And it’s streamlined its cloud services and DevOps teams into one group for the whole company.

  • Thanks to Red Hat, India's biggest stock exchange is now the world's fastest

    "Red Hat is now our backbone. Our business cannot run if Red Hat is not there." That is India's biggest stock exchange's CEO talking. Established in 1875, the Bombay Stock Exchange (BSE) is considered to be Asia’s earliest established stock exchange with an overall market capitalization of $1.43 Trillion in 2016 making it the world's 11th largest. Open Source have had many major wins last year, and this has to be one of the biggest.

  • CORD Partners with xRAN to Bring SDN to the RAN

    The Central Office Re-architected as a Data Center (CORD) open source project is partnering with the xRAN Foundation. The two groups plan to work on a software-based, extensible Radio Access Network (xRAN) architecture.

    Apparently, the xRAN Foundation is a new standards group that was formed in late 2016. Deutsche Telekom, a founding member, is hosting a press event at Mobile World Congress next week to introduce the group and explain its mission. Other initial members of xRAN include AT&T, SK Telecom, and Intel.

  • OpenStack sets its sights on the next generation of private clouds

    Today, the OpenStack Foundation is launching the latest version of its platform that allows enterprises to run an AWS-like cloud computing platform in their data centers. Ocata, as the 15th release of OpenStack is called, arrives after only a four-month release cycle, which is a bit faster than its usual six-month cycle, which will resume after this release. The reason for this is a change in how the Foundation organizes its developer events over the course of a release cycle. Because of the shorter cycle, this new release focused more on stability than new features, but it still manages to squeeze a number of new features in as well.

Open source and mainstream are joining forces this week as the Docker software containerisation platform comes under the spotlight at technology-focused network and information sessions in Cape Town and Johannesburg.

"The diversity of our partners at the event − Docker, Microsoft Azure, Atlassian, SUSE and HPE – is a clear indication of the excitement around the Docker platform," says Muggie van Staden, MD of Obsidian Systems.

  • Of Pies and Platforms: Platform-as-a-Service vs. Containers-as-a-Service

    I’m often asked about the difference between using a platform as a service (PaaS) vs. a containers-as-a-service (CaaS) approach to developing cloud applications. When does it makes sense to choose one or the other? One way to describe the difference and how it affects your development time and resources is to look at it like the process of baking a pie.

  • Understanding OpenStack's Success

    At the time I got into the data storage industry, I was working with and developing RAID and JBOD (Just a Bunch Of Disks) controllers for 2 Gbit Fibre Channel Storage Area Networks (SAN). This was a time before "The Cloud". Things were different—so were our users. There was comfort in buying from a single source or single vendor. In an ideal world, it should all work together, harmoniously, right? And when things go awry, that single vendor should be able to solve every problem within that entire deployment.
