  • Kubernetes Monitoring with Prometheus

    Kubernetes makes management of complex environments easy, but to ensure availability it's crucial to have operational insight into the Kubernetes components and all applications running on the cluster. I believe monitoring is the backbone of a good production environment.

    Applications running in containers and orchestrated by Kubernetes are highly automated and dynamic, and so, when it comes to monitoring applications in these environments, traditional server-based monitoring tools designed for static services are not sufficient.

  • CNCF’s Vitess Scales MySQL with the Help of Kubernetes

    A technology developed by YouTube to shard large MySQL databases across multiple servers, Vitess, has become the 16th hosted project of the Cloud Native Computing Foundation.

    Vitess was created for “people who love MySQL for its functionality, but have chosen not to use it because it does not scale well,” said Sugu Sougoumarane, one of the creators of Vitess who is now co-founder and chief technology officer at PlanetScale Data, a still-stealth startup centered around Vitess, in an interview with The New Stack.

  • Deepfence Emerges from Stealth with Container Security Platform

    Sandeep Lahane has been been quietly building his container security startup Deepfence since 2016. On Feb. 13, Deepfence emerged from its stealth mode, announcing the company's Security as a Microservice technology for container security.

    The Deepfence approach uses what the company refers to a a lightweight sidecar container, which runs alongside an organization's existing Docker and Kubernetes container deployments. Deepfence's technology makes use of artificial intelligence (AI) as well as policy driven rules, to help detect potential threats and enforce workload isolation.

  • What is Software Defined Storage?

    Software defined storage (SDS) decouples storage software from the underlying storage devices. It does this by creating a virtualized software management layer that operates above the storage hardware.

    While that definition may reasonably straight forward, many players in the data storage industry debate the specifics and details of what, exactly, is the true definition of SDS.

    Oracle uses the open-source OpenStack cloud platform as the basis for its cloud services. Oracle has been actively involved in OpenStack since at least 2014, when it announced support for OpenStack on both Oracle Linux and Solaris-based systems.

  • Oracle’s Cloud: Perception vs. Reality

    Oracle announced an impressive cloud computing initiative this week; it was very nicely packaged. But the company initially did not even take the cloud seriously, and was very slow to realize that this cloud thing was going to be massively disruptive.

  • 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.
