  • Bring your Kubernetes workloads to the edge

    Although cloud-based applications continue to grow, some use cases require moving workloads out of cloud data centers. The reason is usually to keep your computing power closer to the users, the source of data, or other things you want to control. Instead of running these workloads as separate entities, you might want to create uniform systems, extending clouds to the edge. This technique is known as edge computing.

    The past few years have seen a proliferation of edge computing infrastructure. Today you have a wealth of options, from running containers directly in container runtimes (such as Podman), to joining nodes to Kubernetes clusters, to running whole lightweight Kubernetes distributions on edge nodes.

    As infrastructure becomes widely accessible, developers need to think through the edge computing journey. An important question in this arena is, How do we build our workloads for this new world? This article discusses the current state of tools for managing containers at the edge, including what WebAssembly (also known as Wasm) offers in this domain and what to expect from the field of edge computing in the near future.

  • Digital transformation: 4 ways to create a sense of urgency

    In the last 18 months, entire industries were pushed to make decisions in days that would typically be debated and planned for months or even years. Customer-facing brands, in particular, were forced to cope with rapid, unpredictable changes in supply, demand, and logistics.

    Adding to these challenges, a recent survey found that nearly 40 percent of respondents give a business only one chance to provide a satisfactory digital experience before moving to another supplier. With just one opportunity to make a lasting impression, many enterprises have made it a top business priority to create more personalized customer experiences.

    Here are four key actions that will bring increased urgency to your digital transformation strategies.

  • 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.
