  • How SREs can achieve effective incident response

    Incident response includes monitoring, detecting, and reacting to unplanned events such as security breaches or other service interruptions.

  • Cloud consultants: 4 questions to ask about your strategy

    In the classic corporate satire Office Space, “the Bobs” – two management consultants brought in to trim the fat from fictional software company Initech – pepper a beleaguered “engineer liaison” with questions about his (apparently minimal) job duties before getting to the punchline: “What would you say … you do here?”

    It’s a great bit, but in a real-life IT shop the script should be flipped: It’s you who needs to ask the consultants about what they do – and ideally not months (or years) after you’ve engaged with them.

    Consultants can deliver significant value to IT leaders and their teams, especially when your strategic ambitions outpace the expertise and resources available in-house. But this usually only occurs when you have a strong shared understanding of their role and how you can best work together.

  • IT leadership: 6 questions mentors should ask mentees

    One of the most rewarding things I’ve done in my professional career is to serve as a mentor for others. Numerous people freely gave their time and expertise to help me get to where I am today, so I’m always happy to return the favor.

    The benefits of mentoring are plentiful. According to a SurveyMonkey study, nine out of 10 employees who have a career mentor are happy in their jobs.

    At Improving, we have an initiative that is part career coaching, part mentorship. The aim is to help our people reach their career goals, and the approach is customized to each person’s needs.

  • 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.
