Server: Ubuntu Server, Canonical's Embrace of Buzzwords and LF on Storage

Filed under
Server
  • Ubuntu Server development summary – 11 September 2018

    Cloud-init version 18.3.39 adds jinja template support for user-data scripts and cloud config. As part of this feature, any cloud metadata crawled by cloud-init is presented as template variables. Any cloud-provided metadata such as ip addresses, hostname, region, availability_zone can be referenced in user-data cloud config or scripts without having to crawl and parse metadata in separate tooling.

    Since cloud-init generalizes some of this instance metadata across all clouds, it now allows user-data to be more flexible when deploying to different cloud platforms. See Using instance metadata for more information.

  • What is multi-cloud?

    Tech companies, Canonical included, have a problem. That problem is living in buzzwords and jargon, and then assuming everyone knows what we are talking about.

    At Canonical we call them ‘Canonicalisms’, other companies have their own names for it.

    Whilst we can joke about it, this over-reliance on jargon is a genuine barrier to our audience, developers, customers, people in need of technical help, people in need of assistance in understanding what all these buzzwords are. The jargon is a barrier to people understand what something like the cloud is, in its many different guises, and how these different architectures and strategies can be used for tangible business benefits.

    Fortunately, that’s a problem which is solvable.

    Canonical has decided to produce a whitepaper that details everything you need to know to understand every type of cloud from public to private and managed to multi-cloud. But, we haven’t stopped there, because these technologies don’t live in a bubble, they’re connected to technologies such as Kubernetes, containers, serverless computing, servers and virtual machines.

    Still, understanding the basics about these different technologies is only a piece of the picture, which is why we’ve also included guidance on the best strategies to use, use cases, when and where to deploy and make it a success.

  • Know Your Storage: Block, File & Object

    Dealing with the tremendous amount of data generated today presents a big challenge for companies who create or consume such data. It’s a challenge for tech companies that are dealing with related storage issues.

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.
