  • Red Hat Bolsters Cloud-Native and Edge Portfolio

    Red Hat today at the KubeCon + CloudNativeCon North America conference unfurled a bevy of updates that promise to both make it easier to build and deploy applications on fleets of clusters based on its distribution of Kubernetes and manage the overall environment.

  • Software’s Big Skill-Up, Learning The Way To Cloud-Native

    In this regard, Red Hat is providing ways for cloud-native deployments to be executed more quickly and accurately. Red Hat Advanced Cluster Management for Kubernetes 2.4 provides ‘policy templating’ (a policy being the prescripted way data is managed in any given system) and zero-touch provisioning. Of particular use in edge i.e. Internet of Things (IoT) computing environments, Red Hat also here combines what the company calls ‘validated patterns for edge’ to reduce deployment complexity, save time and improve the accuracy of the cloud-native systems being developed.

  • Automotive transformation to software-defined vehicles: Red Hat point of view and synergies with state-of-the-art IT

    Building a dream car doesn’t just revolve around factors like horsepower and interior finishes anymore. The automotive industry is going through some big changes as the electric vehicle market revs up and edge computing extends new capabilities for vehicle connectivity.

    At Red Hat, we are working to enable a number of edge use cases—from telecommunications use cases with core network infrastructure for radio access networks to distributed computing for retail environments and manufacturing environments.

    During the "Automotive transformation to software-defined vehicles" Ask the Expert session at Red Hat Summit this year, we discussed the car as the ultimate edge server and the role of Red Hat and other open source contributors in this fast-evolving industry. This post will cover some of the highlights from the session.

  • Remote and hybrid work: 4 tips to ease onboarding

    Onboarding new team members has been a struggle for many companies that rapidly switched to remote work or hybrid work. As an IT leader, you know that business success depends on having reliable and talented colleagues working together, whether virtually or in person. So how do you overcome the remote onboarding challenge?

    Answering this question can be particularly difficult if yours is a "traditional" industry with a baked-in corporate culture. A company that’s been in the financial services industry for 100 years, for instance, is likely to have a tougher time revamping its onboarding processes than, say, a start-up that specializes in cloud services.

    That’s not corporate ageism; it’s a trend that's been seen time and time again – and it will, unfortunately, inhibit your ability to onboard talented developers and other technologists with a diversity of backgrounds and experience.

    The good news? Any organization, in any industry, can successfully “virtualize” its onboarding practices. In doing so, they invigorate their IT teams and add collaborative, innovative people.

  • How to install Docker Engine on CentOS

    Docker Engine is an open containerization program for Linux and other platforms. Docker Engine manages self-contained “containers” that operate similar to virtual machines.

  • How to Use the Terraform Command Line Interface (CLI) on Ubuntu

    Terraform is a framework for building and configuring infrastructure as code, with a command-line interface and DSL language. Terraform can manage existing and popular service providers as well as custom in-house solutions to build and configure complete distributed data centers. The Terraform Command Line Interface (CLI) lets you use Terraform without having to write any code or configuration files. It's an ideal way to prototype infrastructure changes with your team before writing code, deploying configurations locally on your machine, or pushing them into production. The CLI builds off of the terraformspec file format that was created for this purpose by third parties such as HashiCorp Nomad CLI Toolkit. The CLI toolkit implements a JavaScript DSL to define the infrastructure and uses the same configuration format in both Terraform and the CLI. The CLI toolkit also provides commands to generate infrastructure templates, compose infrastructure components into complete solutions, and manage changes. The entire Terraform workflow is driven by stateless functions that are defined in code and executed by Terraform every time you make a change. This allows you to think about your infrastructure as a single design that can be easily modified at runtime without reloading your configuration or modifying your codebase. A number of IT professionals and companies use the Terraform command-line interface to manage and even create new infrastructure or new cloud infrastructures. The terraform command-line interface can provide a more robust method for automating changes that would take too long to perform by hand. It is a powerful tool for managing infrastructure.

  • Transfer Files Between Dropbox And Google Drive With Rclone - OSTechNix

    Rclone has a wealth of features. Generally, Rclone is used to copy files from the local drive to a cloud storage provider like Dropbox or Google Drive and vice versa. How about copying files between two different cloud providers? Yes, It is also possible! In this brief guide, we will see how to transfer files between Dropbox and Google Drive with Rclone in Linux. As you may already aware, Rclone doesn't use the local drive while synchronizing files between two different cloud providers. Rclone employs server-side transfers to minimize the local bandwidth use and transfers the data from one provider to another without using local disk. Hence, it reduces disk writes and local network bandwidth significantly.

  • Grafana Weather Dashboard using InfluxDB and an ESP32 - In-Depth Tutorial - The DIY Life

    Following one of my previous projects where I built a weather station dashboard using InfluxDB and Grafana on the reTerminal, I had quite a few requests to do a more in-depth tutorial on how to get each part set up and running. So in this tutorial, I’m going to be going through each part of the process, step-by-step, so that you can get a similar setup running on your Raspberry Pi. In this example, we’re going to use an ESP32 as our data collection node to collect temperature, humidity and pressure readings from some attached sensors. It’ll then post these readings to an InfluxDB database and we’ll then use Grafana to visualise the data. Don’t worry if you don’t understand what these are or how they work together just yet, I’ll explain them each in more detail as we work through them.

  • The Evolution of Linux: a success story from Fujitsu and SUSE | SUSE Communities [Ed: Revisionism that omits GNU]

    Technological innovations are often considered to be ideas and solutions that take off immediately. But the evolution of Linux tells a different story: From humble beginnings in the 1990s, Linux has grown slowly and steadily to become a leading operating system in the business world, and now a business-critical operating system to run SAP. During this time, Fujitsu and SUSE have continued to innovate together, helping businesses everywhere to realize the benefits of Linux by running their SAP applications on it. I caught up with Jürgen Ellwanger and Martin Werner at the Global Fujitsu SAP Competence Centre to find out more about how Fujitsu and SUSE supported the evolution of Linux through a partnership of collaboration and innovation.
