  • Deploying Kubernetes at the edge – Part I: building blocks

    What exactly is edge computing? Edge computing is a variant of cloud computing, with your infrastructure services – compute, storage, and networking – placed physically closer to the field devices that generate data. Edge computing allows you to place applications and services closer to the source of the data, which gives you the dual benefit of lower latency and lower Internet traffic. Lower latency boosts the performance of field devices by enabling them to not only respond quicker, but to also respond to more events. And lowering Internet traffic helps reduce costs and increase overall throughput – your core datacenter can support more field devices. Whether an application or service lives in the edge cloud or the core datacenter will depend on the use case.

    How can you create an edge cloud? Edge clouds should have at least two layers – both layers will maximise operational effectiveness and developer productivity – and each layer is constructed differently.

  • Certifications for DevOps engineers

    DevOps teams appreciate using DevOps processes, especially in multi- and hybrid cloud infrastructures, for many reasons. For one thing, DevOps breaks down barriers and enables agile software development and continuous delivery of IT operations. It is also popular in enterprises because it helps accelerate business outcomes through digital transformation.

  • SUSE YES Certification for SLE 15 SP1 Now Available
  • Deploy a SUSE Enterprise Storage test environment in about 30 minutes
  • MTTR is dead, long live CIRT

    The game is changing for the IT ops community, which means the rules of the past make less and less sense. Organizations need accurate, understandable, and actionable metrics in the right context to measure operations performance and drive critical business transformation.

    The more customers use modern tools and the more variation in the types of incidents they manage, the less sense it makes to smash all those different incidents into one bucket to compute an average resolution time that will represent ops performance, which is what IT has been doing for a long time.

  • RHEL 8 enables containers with the tools of software craftsmanship

    With the release of the Red Hat Enterprise Linux 8, there is a new set of container tools which allow users to find, run, build, and share containers. This set of tools allows you to start simple with podman, and adopt more sophisticated tools (buildah, and skopeo) as you discover advanced use cases. They are released in two streams, fast and stable, to meet developer and operations use cases. Finally, these tools are compliant with the same Open Containers Initiative (OCI) standards, just like Docker, allowing you go build once, and run anywhere.

  • IBM's big deal for Red Hat gives it a chance to reshape open source
  • Cloudera Commits to 100% Open Source

    The old Cloudera developed and distributed its Hadoop stack using a mix of open source and proprietary methods and licenses. But the new Cloudera will be.

  • Cloudera relents, adopts pure open-source strategy

    Although billed as a “merger of relative equals,” last fall’s combination of Cloudera Inc. and Hortonworks Inc. was by all accounts a Cloudera acquisition of its smaller big-data rival. But it now appears that Hortonworks’ open-source business model has won the day. Cloudera Wednesday quietly announced changes to its licensing policy that will make its entire product portfolio available under open-source terms, effectively adopting Hortonworks’ business model.

    The move has important implications for the industry’s ongoing debate about how business models can be built upon a foundation of free software. Although Cloudera is a major contributor to open-source projects, its decade-old business has always been based on selling licensed software.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
