  • DevOps still very much a work in progress, survey suggests

    That's the key takeaway from a recent survey of 2,045 IT managers and professionals, released by Quali, an IT automation solutions provider. While most people in enterprises would say at this point that they have DevOps underway in some shape or form, achieving agility is another story.

  • IBM chases Google, Microsoft with Kubernetes in the cloud

    It's only a matter of time before every major cloud vendor offers a version of Kubernetes as a service. Now it’s IBM’s turn.

  • In The Virtualization Space, Containers Are Making A Move

    Wow has it been a whirlwind over the last ten years in the virtualization space. Where once Xen and then KVM sat on the pedestal, the baton has been passed to the projects revolved around containers. Names like Docker, Kubernetes and Mesos are most often mentioned. As is generally the case in the FLOSS arena, evolution is a constant. Therefore, if one is in the DevOps arena, it is time to familiarize yourself with containers if you have not already done so.

  • The DOE and NSA Construct Doomsday Scenario for American HPC

    One last point. The Chinese economy continues to expand faster than that of the US, and, depending on who you talk to, will reach the size of the US sometime between 2018 and 2028. Such an economy would be expected to field an HPC capability on par with that of the US. Furthermore, China and the US should both be able to maintain an indigenous and self-sustaining HPC capability for their own use, and it’s unreasonable to think either could prevent the other from doing so. In such a world, the US may no longer enjoy technological supremacy, but it can surely have the wherewithal to control its own future in HPC.

  • [Older] Getting Down To Bare Metal On The Cloud

    When you think of the public cloud, the tendency is to focus on the big ones, like Amazon Web Services, Microsoft Azure, or Google Cloud Platform. They’re massive, dominating the public cloud skyline with huge datacenters filled with thousands of highly virtualized servers, not to mention virtualized storage and networking. Capacity is divvied up among corporate customers that are increasingly looking to run and store their workloads on someone else’s infrastructure, hardware that they don’t have to set up, deploy, manage or maintain themselves.

  • Avoid complex infrastructure when building simple things

    For local development, go crazy. For real production use.. I think you should avoid this until you’re the size of business that someone else will do this for you. If this seems controversial do the math: include backing it up, patching it, keeping it highly available, the time spent not working on your differentiating features etc. There are plenty of datastore services available that will do all this for you and let you focus your limited time on your app, and they’re really very cheap when you consider the actual cost of running a production database. Write your app so that the cost of moving to your own database later if you need to is unlikely to be high. Managing a simple web app instead of managing a web app, a production database, a message queue etc is a big win.

  • Docker to Donate its Container Runtime, containerd, to the Cloud Native Computing Foundation

    Docker plans to donate its containerd container runtime to the Cloud Native Computing Foundation, a nonprofit organization dedicated to organizing a set of open source container-based cloud-native technologies.

    In December, Docker released as open source the code for containerd, which provides a runtime environment for Docker containers. By open sourcing this component of the Docker stack, the company wanted to assure users, partners, and other actors in the container ecosystem that the core container component would remain stable, and that the community would have a say in its advancement.

  • Docker at 4: The Container Revolution Continues

    The open-source Docker container project held events around the globe last week as it celebrated its fourth birthday. Docker is more popular than ever as the standard bearer for the container microservices DevOps movement, though Docker Inc. as a company now faces more challenges than ever before as well.

    Three years ago, I wrote about the first anniversary of Docker, predicting significant growth in 2014. As it turned out, I was right about the growth, though I was wrong about Docker Inc. Back in 2014, I had predicted that Docker Inc. would likely be acquired, but to date that hasn't happened—though there has been no shortage of speculation over the last three years.

    Docker Inc. and the open-source container ecosystem that Docker helped create have evolved significantly since 2014, and over the course of the project's four-year existence. This past year has arguably been the most significant yet for Docker Inc., both as a business and an open-source project.

  • What is Linux VPS Hosting?

    Basically, Linux VPS stands for a virtual private server running on a Linux system. A virtual private server is a virtual server hosted on a physical server. A server is virtual if it runs in a host computer’s memory. The host computer, in turn, can run a few other virtual servers.

  • How the cloud can kickstart your business

    So, you’re a developer with a great tech idea. You have a vision for a world-beating product, perhaps even one that defines a new category. But the journey from idea to execution is long, painful, and often expensive. The cloud can help developers realize their dreams while minimizing capital outlay. Here’s how.

    In the early days and even into maturity, startups are experimenting. They are testing assumptions, prototyping new features and ideally looking at usage patterns to see how these features are being received. The technology to support this cycle of innovation can be one of the most critical costs for a tech startup. Developing, testing and deploying these experiments isn’t cheap. No startup wants to buy and maintain its own server technology while it churns new ideas. Infrastructure is a distraction for these companies.

  • NFV vs. VNF: What's the difference?

    Networking professionals sometimes use the terms virtual network functions, or VNF, and network functions virtualization, or NFV, interchangeably, which can be a source of confusion. However, if we refer to the NFV specifications the European Telecommunications Standards Institute, or ETSI, sets forth, it becomes clear the two acronyms have related but distinct meanings.

  • Parity Check: Expectations Around Monitoring Have Changed

    Monitoring software company BigPanda recently published its second annual State of Monitoring report, which provides data and a few answers. It is based on responses from over 1,500 IT pros. When comparing the 2017 and 2016 reports we found that many things have not changed. The top IT concerns are about security and downtime. The top IT monitoring challenges are quick remediation of service disruptions, getting money to buy monitoring tools and reducing the number of unimportant alerts being generated. Interestingly, even the top performance key performance indicators (KPIs) are the same, with customer satisfaction cited by 73 percent, followed service level agreements (SLAs) compliance, incident volume and mean time to repair (MTTR).

  • IT Automation Best Practices for Network Engineers and Architects

    Software-defined networking (SDN) for L2 and L3 (layer two and three) networking and network function virtualization (NFV) for L4-L7 network services have remained elusive for many IT departments due to the lack of maturation of the technology or specialized skills needed to implement them. But, network automation doesn’t have to be an all or nothing proposition. Software-defined approaches for application and networking services combined with scripting and orchestration tools such as Ansible are enabling practical approaches to network automation that doesn’t require boiling the ocean. In this article, I’ll examine some best practices for network automation in L4-L7 services that can drive immediate improvements in your network.

  • Serverless: Redefining DevOps

    There is a dramatic shift underway in how many in house, and commercial, DevOps tools are being created and used

    The growth in interest in serverless computing continues at pace, and for many organisations serverless technologies such as AWS Lambda, Azure Functions or Google Cloud Functions are becoming an essential part of their development and operations toolkit.

  • IT Workers Say Their Companies Are Migrating to Virtual Infrastructures, Study Says

    An overwhelming 86 percent of respondents to a Chef survey of IT practitioners have completed or are in the progress of migrating from a physical infrastructure to a virtual one.

    Chef interviewed more than 1,500 global IT workers that use Chef servers and found that many emerging and legacy technologies are being rebuilt around the needs of developers. In addition, companies are piloting and adapting new technologies like cloud, containers, and microservices in search of speed.

  • ARM Antes Up For An HPC Software Stack

    The HPC community is trying to solve the critical compute challenges of next generation high performance computing and ARM considers itself well-positioned to act as a catalyst in this regard. Applications like machine learning and scientific computing are driving demands for orders of magnitude improvements in capacity, capability and efficiency to achieve exascale computing for next generation deployments.

    ARM has been taking a co-design approach with the ecosystem from silicon to system design to application development to provide innovative solutions that address this challenge. The recent Allinea acquisition is one example of ARM’s commitment to HPC, but ARM has worked with the HPC community to develop compilers, libraries, and other key tools that are now available for ARM HPC deployments in 2017.

  • Mesosphere Extends Data Services Reach

    In general, Hsu says, IT organizations are making it clear that they need platforms that go well beyond merely orchestrating containers and images. Applications running in production environments require access to a full range of services that IT operations teams need to be able to manage at scale, he says. Container orchestration engines such as Kubernetes may meet the requirements of an individual developer, but most IT operations teams are looking manage multiple applications accessing hundreds of services that all need to be centrally managed, says Hsu.

  • 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 peril in counting source lines on an OSS project
    There seems to be a phase that OSS projects go through where as they mature and gain traction. As they do it becomes increasingly important for vendors to point to their contributions to credibly say they are the ‘xyz’ company. Heptio is one such vendor operating in the OSS space, and this isn’t lost on us. :) It helps during a sales cycle to be able to say “we are the a big contributor to this project, look at the percentage of code and PRs we submitted”. While transparency is important as is recognizing the contributions that key vendors, focus on a single metric in isolation (and LoC in particular) creates a perverse incentive structure. Taken to its extreme it becomes detrimental to project health.
  • An Open Source Unicycle Motor
    And something to ponder. The company that sells this electric unicycle could choose to use a motor with open firmware or one with closed firmware. To many consumers, that difference might not be so significant. To this consumer, though, that’s a vital difference. To me, I fully own the product I bought when the firmware is open. I explain to others that they ought to choose that level of full ownership whenever they get a chance. And if they join a local makerspace, they will likely meet others with similar values. If you don’t yet have a makerspace in your community, inquire around to see if anyone is in the process of forming one. Then find ways to offer them support. That’s how we do things in the FOSS community.
