  • Kubernetes Adoption Challenges Solved

    The business wants better software, brought to market faster. Enterprise IT wants to manage cost and risk. The problem for large, complex organizations is that they need to accomplish these objectives and still maintain existing business operations. It is like changing the wheels of an F1 race car at full speed without a pit stop.

    While some see cloud as a cure-all for the digital transformation goals set by CEOs, the reality of running large systems at scale in the cloud is rife with inconsistent interfaces, and the differing topologies of multiple cloud providers.

    Cloud providers are painting themselves as the heroes that will enable digital transformation. Each one has a specific implementation of its infrastructure, and some are now offering on-premises datacenter hybrid-cloud appliances. The lack of homogeneity in their cloud technology will have a detrimental effect to those on the journey towards digital transformation, however. Developers and enterprise IT engineers have to learn the nuances of at least two clouds: public and private. Sometimes, they’re required to deal with even more. As a result, cost increases, complexity becomes common and developer productivity decreases.

  • Hardware Accelerated SSL/TLS Termination in Ingress Controllers using Kubernetes Device Plugins and RuntimeClass

    A Kubernetes Ingress is a way to connect cluster services to the world outside the cluster. In order to correctly route the traffic to service backends, the cluster needs an Ingress controller. The Ingress controller is responsible for setting the right destinations to backends based on the Ingress API objects’ information. The actual traffic is routed through a proxy server that is responsible for tasks such as load balancing and SSL/TLS (later “SSL” refers to both SSL or TLS ) termination. The SSL termination is a CPU heavy operation due to the crypto operations involved. To offload some of the CPU intensive work away from the CPU, OpenSSL based proxy servers can take the benefit of OpenSSL Engine API and dedicated crypto hardware. This frees CPU cycles for other things and improves the overall throughput of the proxy server.

    In this blog post, we will show how easy it is to make hardware accelerated crypto available for containers running the Ingress controller proxy using some of the recently created Kubernetes building blocks: Device plugin framework and RuntimeClass. At the end, a reference setup is given using an HAproxy based Ingress controller accelerated using Intel® QuickAssist Technology cards.

  • History of Container Technology Offers Lessons for Future

    Many of the issues associated with container technology are due to infrastructure decisions made long before containers, cloud and the internet even existed.

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.
