  • Microservices and containers: 5 pitfalls to avoid

    Because microservices and containers are a match made in heaven, it might seem like nothing could go wrong. Let’s get these babies into production as quickly as possible, then kick back and wait for the IT promotions and raises to start flooding in. Right?

    (We’ll pause while the laughter subsides.)

    Yeah, sorry. That’s just not how it works. While the two technologies can be a powerful combination, realizing their potential doesn’t happen without some effort and planning. In previous posts, we’ve tackled what you should know at the start. But what about the most common problems organizations encounter when they run microservices in containers?

  • This Week in Numbers: Container Storage Preferences for Kubernetes

    The types of logical storage structures used in today’s Kubernetes deployments offer some deeper revelations into the nature of workloads being deployed. Block storage is king, having been cited by two-thirds (66 percent) of respondents in our survey for The State of the Kubernetes Ecosystem as being involved with their Kubernetes implementations.

    Few deployments are relegated to only one type of logical storage, so it is telling that just fewer than half of the respondents (46 percent) cited file storage as the type they’re using. Newer, cloud-native applications with microservices architectures and that utilize databases or data structures, typically don’t need a file system because they are not interacting with data through an operating system. A 46 percent figure is quite high, signaling that more integration with older application types is taking place.

    Object storage is used by 29 percent of respondents, which is relatively high compared with adoption rates for object storage that we’ve seen in the past. Since object storage is scalable, developers working on distributed systems likely have experience with it already. In addition, object storage is often used to deliver static content for websites, which is also a common type of workload for Kubernetes.

  • Patch CDK #1: Build & Release

    Happens all the time. You often come across a super cool open source project you would gladly contribute but setting up the development environment and learning to patch and release your fixes puts you off. The Canonical Distribution of Kubernetes (CDK) is not an exception. This set of blog posts will shed some light on the most dark secrets of CDK.

  • Maxta adds Red Hat in plan to help customers dodge ‘VMware tax’

    Hyper-converged infrastructure maker Maxta has announced it now supports the Red Hat Virtualization hypervisor and can allow customers to migrate data from VMware to Red Hat or run VM in both environments.

  • ​SUSE Studio merges with Open Build Service

    When SUSE first introduced SUSE Studio in 2010, it was a radical change. You could build your own Linux distribution without being a Linux expert. Today, we use custom Linux images inside containers, virtual machines (VM), and every cloud worth its name every day. So SUSE is updating SUSE Studio by merging it with its Open Build Service (OBS) to create a better tool for bundling packages with Linux distributions to deliver customized Linux images. The new product's name will be SUSE Studio Express.

  • When Microsoft met SUSE: This Windows-Linux partnership gets stronger every day [Ed: "Linux purists hated that partnership". Not Linux. Not purists. GNU. And people who value freedom.]

    Linux purists hated that partnership. But my, how things have changed! Today, Microsoft has joined The Linux Foundation; all the major Linux distributions, including Debian and Red Hat are available on Microsoft's Azure cloud; and Microsoft recently joined the Open Source Initiative.

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.
