Server

The Cloud Foundry Foundation on Wednesday announced the launch of a worldwide cloud-native developer certification initiative.

The foundation created the cloud developer certification program to fill the widening gap of trained programmers for cloud apps and services. The Linux Foundation -- which has trained and certified more developers on open source software than any organization in the world -- will provide the instruction.

More than a dozen leading technology, education and systems integration organizations around the world will participate in the cloud certification program. Companies involved in the initial training and certification rollout include Engineer Better, IBM, Pivotal, Resilient Scale, SAP, Stark and Wayne, and Swisscom.

  • Setting the Record Straight: containers vs. Zones vs. Jails vs. VMs

    I’m tired of having the same conversation over and over again with people so I figured I would put it into a blog post.

    Many people ask me if I have tried or what I think of Solaris Zones / BSD Jails. The answer is simply: I have tried them and I definitely like them. The conversation then heads towards them telling me how Zones and Jails are far superior to containers and that I should basically just give up with Linux containers and use VMs.

    Which to be honest is a bit forward to someone who has spent a large portion of her career working with containers and trying to make containers more secure. Here is what I tell them:

  • [Old] Hadoop Has Failed Us, Tech Experts Say

    The Hadoop community has so far failed to account for the poor performance and high complexity of Hadoop, Johnson says. “The Hadoop ecosystem is still basically in the hands of a small number of experts,” he says. “If you have that power and you’ve learned know how to use these tools and you’re programmer, then this thing is super powerful. But there aren’t a lot of those people. I’ve read all these things how we need another million data scientists in the world, which I think means our tools aren’t very good.”

  • Docker at Travis

    The Travis CI service offers a free Continuous Integration (CI) service for open source projects hosted at GitHub.

  • Kubernetes 1.6: Multi-user, Multi-workloads at Scale

    In this release the community’s focus is on scale and automation, to help you deploy multiple workloads to multiple users on a cluster. We are announcing that 5,000 node clusters are supported. We moved dynamic storage provisioning to stable. Role-based access control (RBAC), kubefed, kubeadm, and several scheduling features are moving to beta. We have also added intelligent defaults throughout to enable greater automation out of the box.

  • Core OS offers Tectonic preview for Microsoft Azure

    If you recall the early days of Docker and OpenStack, it was quite a challenge to get OpenStack cloud up and running, and even when you got it running, managing it was a tricky task in its own right.

  • VisionMobile Report Lays Out Developer Salaries by Skill, Software Sector, and Location

    In 2017, that means skilled cloud and backend developers, as well as those who work in emerging technologies including Internet of Things (IoT), machine learning and augmented/virtual reality (AR/VR) can make more money -- tens or sometimes hundreds of times more -- than frontend web and mobile developers whose skills have become more commoditized.

    “In Western Europe, for example, the median backend developer earns 12% more than the median web developer; a machine learning developer makes 28% more,” according to the report.

  • Cilium leverages Linux kernel for advanced container networking

    Networking has always been one of the most persistent headaches when working with containers. Even Kubernetes—fast becoming the technology of choice for container orchestration—has limitations in how it implements networking. Tricky stuff like network security is, well, even trickier.

    Now an open source project named Cilium, which is partly sponsored by Google, is attempting to provide a new networking methodology for containers based on technology used in the Linux kernel. Its goal is to give containers better network security and a simpler model for networking.

  • Modules vs. microservices

    Much has been said about moving from monoliths to microservices. Besides rolling off the tongue nicely, it also seems like a no-brainer to chop up a monolith into microservices. But is this approach really the best choice for your organization? It’s true that there are many drawbacks to maintaining a messy monolithic application. But there is a compelling alternative which is often overlooked: modular application development. In this article, we'll explore what this alternative entails and show how it relates to building microservices.

  • What Is Kubernetes?

    Kubernetes is open source software for automating deployment, scaling, and management of containerized applications. The project is governed by the Cloud Native Computing Foundation, which is hosted by The Linux Foundation. And it’s quickly becoming the Linux of the cloud, says Jim Zemlin, executive director of The Linux Foundation.

    Running a container on a laptop is relatively simple. But connecting containers across multiple hosts, scaling them when needed, deploying applications without downtime, and service discovery among several aspects, are really hard challenges. Kubernetes addresses those challenges with a set of primitives and a powerful API.

  • 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.

  • 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.
