Red Hat on Servers: Kubernetes, IBM, Latest Results and OKD

  • Will Kubernetes Slow Down My Database?

    I know my database will be slower on Kubernetes and cloud native storage, but HOW MUCH slower? This is a question everyone thinking of moving traditionally hosted stateful services like database to Kubernetes ask all the time. And until now, we haven’t had good answers. This presentation will detail a series of microbenchmarks on PostgreSQL running on and off Kubernetes in a variety of configurations, including bare metal, local storage, gluster, and rook. You’ll get a solid idea of what the cost in latency and throughput is for abstracting away your storage problems, and be able to make platform decisions for yourself.

  • Red Hat Global Customer Tech Outlook 2019: Automation, cloud, & security lead funding priorities

    As we round out 2018, it’s time to reflect on how the year has gone and our plans for the coming year. For the fifth consecutive year, we reached out to our customers to hear where they are in their technology journey and where they want to go in 2019. For our annual Red Hat Global Customer Tech Outlook, we surveyed more than 400 Red Hat customers around the world, with respondents from 51 countries. These IT leaders weighed in about their current challenges, their deployment strategies, technologies they are excited about, as well as budget and technology priorities for 2019.

  • IBM’s $37 Billion Acquisition of Red Hat

    IBM (NYSE: IBM) and Red Hat (NYSE: RHT), the world’s leading provider of open source cloud software, have reached a definitive agreement under which IBM will acquire all of the issued and outstanding common shares of Red Hat for $190.00 per share in cash, representing a total enterprise value of approximately $34 billion.

  • Red Hat sales softer than expected ahead of IBM purchase

    The company reported third quarter earnings of $94 million, or 51 cents a share, on revenue of $847 million, up 13 percent from a year ago. Non-GAAP earnings for the third quarter were 96 cents a share.

    Wall Street was looking for non-GAAP third quarter earnings of 87 cents a share on revenue of $852.8 billion. Red Hat said currency fluctuations hurt sales somewhat. On a constant currency basis, Red Hat sales would have been up 15 percent.

  • Will Anyone Be Fired for Hiring Big Purple?

    While the cloud offers a compelling cost advantage, lower cost is not the only differentiator that will define tomorrow’s winners and losers in the cloud marketplace. Might the purple cloud — made up of Big Blue’s cloud and Red Hat’s Linux and Kubernetes distro — be the most secure?

    Remember the saying, “No one ever gets fired for hiring Big Blue”? At a time when technology seemed to be changing fast, executives wanted to reduce risk and play it safe. This was before the cloud and at a time when distributed computing seemed like some new-age religion.

    While most bloggers seem focused on why IBM would pay $34 billion for Red Hat, I thought it might be timely to point out the recent Kubernetes vulnerability, CVE 2018-1002105. This vulnerability — announced by Google and credited to Darren Shepherd’s discovery — remains too new at the time of this writing to even be found in the NIST’s National Vulnerability Database.

  • A user story about an OKD update from 3.9 to 3.10

    The OpenShift community produces a lot of interesting tutorials about how to try new solutions and configurations but unfortunately they are mostly based on a minimal setup such as MiniShift, which is definitely a cool gimmick, but badly resembles a real cluster setup. Often those posts only concentrate on the known good path about how something is supposed to function in the best case. They rarely mention how it could be debugged or fixed if it doesn’t work as expected. As all of us know, the more complex a system is, the more can go wrong and this technology is no exception especially when run in a real distributed setup. To give you some insight in how such procedures can go wrong, I’d like to share the experience I made when I tried to update my multi-master/multi-node OKD cluster. As an experienced Linux engineer or developer you might think that version updates are nothing special or exciting, but this experience will disabuse you. I hit many issues and here is how I did it.

  • 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.
