  • Telco cloud: what is that? | Ubuntu

    Telco cloud or a network function virtualisation infrastructure (NFVI) is a cloud environment optimised for telco workloads. It is usually based on well-known technologies like OpenStack. Thus, in many ways, it resembles ordinary clouds. On the other hand, however, it differs from them. This is because telco workloads have very specific requirements. Those include performance acceleration, high level of security and orchestration capabilities. In order to better understand where those demands are coming from, let’s start with reviewing what kind of workloads are telcos running in the cloud.

  • OpenStack at 10 – from peak to plateau of productivity | Ubuntu

    This week is the latest Open Infrastructure Summit, in a week where the OpenStack Foundation became the Open Infrastructure Foundation to reflect the expansion of the organisation’s mission, scope and community to advance open source over the next decade to support open infrastructure. It is also ten years since OpenStack launched and a lot has changed during that time.

    We asked freelance journalist, Sean Michael Kerner, to share his views on the last ten years. Sean is a freelance journalist writing on myriad IT topics for publications around the world. He has spoken at more OpenStack events than he cares to remember. English is his second language (Klingon his first). Follow him on Twitter @TechJournalist.

    10 years ago in July 2010, I got an unusual pitch from a PR person. It was the beginning of a long and winding road that defines my experience and viewpoint on OpenStack.

    Unlike the usual spate of product and open source pitches from vendors that I got at the time (and still get), the pitch I got on the sunny July afternoon was an offer to speak with the CTO of IT at NASA. It was an offer I couldn’t refuse – and I suspect it’s also the reason why OpenStack got so much attention early on – it was literally ‘rocket science’. In a 2012 video interview I did with Chris Kemp after he left the role of CTO at NASA to start his own OpenStack startup, he told me that in his view OpenStack could well become one of NASA’s great contributions to society.

  • Canonical & Ubuntu at KubeCon NA Virtual 2020 | Ubuntu

    By now it’s no surprise that KubeCon NA is going virtual, like the majority of events worldwide. Is that bad news? Quite the opposite! According to CNCF, this year’s KubeCon EU – the first KubeCon to ever be hosted virtually – made it possible for over 18,700 Kubeheads to sign up, 72% of which were first-time KubeCon + CloudNativeCon attendees. In other words, as we have all believed for so many years now, tech is helping the community grow and get closer.

  • Production-Ready Notebooks for End-to-End ML Workflows With Kubeflow

    Machine Learning projects consist of several distinct steps: first, data validation verifies the state of the collected data. Processing prepares the features so an algorithm can consume them. Model training makes learning feasible, and model validation guarantees generalization. Fine-tuning adjusts the hyper-parameters to obtain the optimum results. Finally, after numerous iterations, the last step deploys a model to staging or production.

    Each of these steps can be a separate process, running at its own cadence, with well-defined inputs and outputs. Thus, data scientists and ML engineers tend to think of these projects like pipelines. If there is something wrong with incoming information, the process could fail or even worse corrupt downstream analytic tasks. Thus, standardizing the process of creating these interconnected actions can make the pipeline more robust.

    In this article, we demonstrate how to turn Jupyter Notebooks into Kubeflow Pipelines and Katib Experiments automatically. Such a system eliminates the erroneous process of manually extracting the bits that make sense in a Notebook, containerize them and launching a Pipeline using explicit Domain-Specific Languages.

  • Support for Istio 1.6 ends on November 21st, 2020

    According to Istio’s support policy, LTS releases like 1.6 are supported for three months after the next LTS release. Since 1.7 was released on August 21st, support for 1.6 will end on November 21st, 2020.

    At that point we will stop back-porting fixes for security issues and critical bugs to 1.6, so we encourage you to upgrade to the latest version of Istio (1.7.3). If you don’t do this you may put yourself in the position of having to do a major upgrade on a short timeframe to pick up a critical fix.

  • Cloud Foundry Foundation Announces Project Updates

    The Cloud Foundry Foundation (CFF) has announced the release of version 1.0 of cf-for-k8s, the release of version 2.5 of KubeCF, and the release of version 4.2 of Stratos.

Automating Server Provisioning in phoenixNap’s Bare Metal Cloud

  • Automating Server Provisioning in phoenixNap’s Bare Metal Cloud with MAAS (Metal-as-a-Service)

    As part of the effort to build a flexible, cloud-native ready infrastructure, phoenixNAP collaborated with Canonical on enabling nearly instant OS installation. Canonical’s MAAS (Metal-as-a-Service) solution allows for automated OS installation on phoenixNAP’s Bare Metal Cloud, making it possible to set up a server in less than two minutes.

    Bare Metal Cloud is a cloud-native ready IaaS platform that provides access to dedicated hardware on demand. Its automation features, DevOps integrations, and advanced network options enable organizations to build a cloud-native infrastructure that supports frequent releases, agile development, and CI/CD pipelines.

    Through MAAS integration, Bare Metal Cloud provides a critical capability for organizations looking to streamline their infrastructure management processes.

  • 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.
