  • RHELvolution: A brief history of Red Hat Enterprise Linux releases from early days to RHEL 5

    The launch of Red Hat Enterprise Linux 8 (RHEL 8) at Red Hat Summit 2019 was a jubilant event. Not only for the many team members around the world who worked to make the next-generation of the world?s leading enterprise Linux platform a reality, but also for customers who are excited to utilize its new capabilities in driving business innovation.

    This is a great time to reflect on what is so special about RHEL 8 by taking a walk through time on the evolution of RHEL. The RHELvolution, if you will. I'll be your guide on this journey, having been at the helm for RHEL engineering since the beginning (2001), starting with Red Hat Enterprise Linux 2.1. And yes, we'll explain why it started with 2.1.

    It has been thrilling to be part of the RHEL team all these years. Having worked on proprietary UNIX operating systems before being at Red Hat, constructing RHEL offered a first hand view of the power of open source. Through collaboration with customers, community and a highly motivated team, we have had a global impact on the IT landscape. Evolving from "lighting up the box" to dynamic infrastructure that helps to advance the state of the art while liberating customers from vendor lock-in (originally at the hardware level, later expanded to hybrid cloud).

  • How Developers Can Survive the Last Mile with CodeReady Workspaces

    As a way to piece together this explosion of available open source tools into simple and coherent single interface for cloud native deployments, the Eclipse Foundation offers the Eclipse Che integrated development environment (IDE).

    Today’s often desperate need for Eclipse Che can be traced back to the evolution of open source tools during the past 10 years. Not only have these tools been evolving, but in many cases, they have been outright created from scratch. That’s posed a bit of a problem for those out on the cutting edge of scalable microservices as the stable infrastructure components of old gave way to a hodgepodge of brand new open source and commercial products and tools.

    Inside each cloud provider, a host of tools can address CI/CD, testing, monitoring, backing up and recovery problems. Outside of those providers, the cloud native community has been hard at work cranking out new tooling from Prometheus, Knative, Envoy and Fluentd, to Kubenetes itself and the expanding ecosystem of Kubernetes Operators.

    Within all of those projects, cloud-based services and desktop utilities is one major gap, however: the last mile of software development is the IDE. And despite the wealth of development projects inside the community and Cloud Native Computing Foundation, it is indeed the Eclipse Foundation, as mentioned above, that has taken on this problem with a focus on the new cloud development landscape.

  • IBM is bringing Red Hat OpenShift to Its Platforms

    IBM is fully embracing Red Hat OpenShift. The company recently announced that it will use Red Hat OpenShift as the primary container environment for all its hybrid cloud offerings. This includes IBM Cloud, IBM Cloud Paks running on OpenShift, an entire field of IBM consultants and services people being trained on OpenShift, and OpenShift on IBM Power Systems and Storage, IBM Z and LinuxONE enterprise platforms. With this move, Red Hat OpenShift has become the preferred Kubernetes platform for IBM to address the needs of increasingly critical container workloads.

    With Red Hat OpenShift running on top of IBM’s cloud and systems, existing IBM customers can unlock the hybrid cloud model for software developers and systems architects. OpenShift can transform IBM systems that have been optimized for data, transaction processing and AI workloads into another resource for container-based infrastructure, inside the fold when it comes to networking, APIs and data access controls.

  • Disaster Recovery Strategies for Red Hat OpenShift

    As increasingly complex applications move to the Red Hat OpenShift platform, IT teams should have disaster recovery (DR) processes in place for business continuity in the face of widespread outages. These are not theoretical concerns. Many industries are subject to regulations that require data protection even in the event of massive failures. For instance, CFR 164.308(7)(ii)(Cool of the HIPAA regulation stipulates that companies must be able to “restore ANY loss of data” (emphasis added) in the event of a failure. Thus for some truly mission critical applications to run on OpenShift, disaster recovery is essential.

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.
