  • MAAS 2.5 : Growing the ecosystem and support for KVM micro-clouds

    Our latest release makes for a very exciting point in the MAAS evolution. As datacenter (DC) infrastructure grows at unparalleled scale fueled by new applications and services such as connected autonomous cars, augmented/virtual reality (AR/VR) and IoT, the need for automated bare metal provisioning has never been more important. Multi-access edge computing and the ongoing shift to 5G will continue to drive cloud architectures ranging from small clusters deployed at actual radio towers all the way to thousands of nodes running in core data centres.

    The agility and speed of discovering, allocating and also repurposing bare-metal servers will be crucial to new services and an automated physical infrastructure lifecycle management. MAAS 2.5 brings new capabilities and improvements to how this can be achieved in a repeatable and reliable way.

  • Container Storage Interface (CSI) for Kubernetes GA

    The Kubernetes implementation of the Container Storage Interface (CSI) has been promoted to GA in the Kubernetes v1.13 release. Support for CSI was introduced as alpha in Kubernetes v1.9 release, and promoted to beta in the Kubernetes v1.10 release.

    The GA milestone indicates that Kubernetes users may depend on the feature and its API without fear of backwards incompatible changes in future causing regressions. GA features are protected by the Kubernetes deprecation policy.

  • Happy Birthday, Chef!

    With Chef, you can automate the way your infrastructure is configured, deployed, and managed. When you’re operating with a single machine, configuration management can be fairly simple. But what happens when your organization scales up? That’s where Chef comes in and saves the day — and a whole lot more.

    Chef ensures your configurations are standardized and continuously enforced in every environment and at any scale. It allows your infrastructure configurations to be testable, portable, and auditable, saving your organization time and monetary resources. You could say Chef is a superhero with all the saving it does.

  • Community collaboration makes for some great OpenStack solutions

    If you follow the evolution of OpenStack, you know how it’s finding its way into all sorts of workloads, from high-level research to car manufacturing to all-new 5G networks. Organizations are using it for everything from the mundane to the sublime and sharing what they’re learning with the OpenStack community.

    Some of the examples offered up at the recent OpenStack Summit Berlin showed that OpenStack is a full-fledged part of the IT mainstream, which means there are a wealth of ideas out there for your own implementation.

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.
