  • How much education do you need to be a Linux sysadmin?

    A recent Enable Sysadmin article by Kevin Casey asks the question, Do I need a college degree to be a sysadmin? I won't spoil his conclusions and findings, but my personal opinion is that all professionals should have a degree, even for entry-level positions. Certainly, this "should" can mean an Associate's degree with the intent of obtaining a Bachelor's degree during job tenure. Many companies provide tuition assistance or complete reimbursement, so there's no reason not to work toward a degree.

    Of course, a degree is no guarantee of employment or insulation from layoffs, but it can be a deciding factor in both instances. If you have two sysadmins and one has a degree and the other doesn't, the manager is more likely to retain the degreed individual with all other aspects of the two being equal or comparable. That assertion comes from observations from working in large enterprise organizations for more than twenty years, through dozens of layoff events.

    At least until an industry standard is created, I doubt that any educational requirements will ever be set. What currently happens is that educational requirements are company-specific and not job-specific.

  • 5 questions to ask before choosing a public cloud provider

    In today’s digital economy, companies are looking for an edge. They want to be more efficient, outpace the competition, and deliver a customer experience that builds loyalty and increases revenue. And they’re exploring hybrid cloud and multicloud strategies to accelerate that transformation.

    In doing so, more and more companies are realizing they’ll need to welcome public clouds into their IT environment. Of course, some might argue public clouds are not a requirement in either a hybrid cloud or multicloud approach—we’ll leave that debate off the table. But as a refresher, multicloud refers to the presence of more than one cloud deployment of the same type (public or private), sourced from different vendors, while hybrid cloud refers to the presence of multiple deployment types (public or private) with some form of integration or orchestration between them.

    Hybrid cloud and multicloud approaches are not necessarily mutually exclusive, but because they always involve more than one cloud deployment and/or cloud type, it’s likely that at some point, a public cloud will be added to the mix. After all, public cloud promises greater elasticity, scalability, and speed of deployment.

  • Architecting messaging solutions with Apache ActiveMQ Artemis

    Over the years, I have hardly seen two messaging architectures that are absolutely the same. Every organization has something unique in the way they manage their infrastructure and organize their teams, and that inevitably ends up reflected in the resulting architectures. Your job as a consultant or architect is to find the most suitable architecture within the current constraints, and educate and guide the customer towards the best possible outcome. There is no right or wrong architecture, but deliberate trade-off commitments in a context.

    In this article, I tried to cover as many areas of Artemis as possible from an architecturally significant point of view. But by doing so, I had to be opinionated, ignore other areas, and emphasize what I think is significant based on my experience. I hope you find it useful and learned something from it. If that is the case, say something on Twitter and spread the word.

  • 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.
