Servers, Buzzwords and Red Hat

  • Containers and microservices and serverless, oh my!

    A new round of buzzword-heavy technologies are becoming relevant to—or at least discussed among—developers, operations professionals, and the tech staff who lead them. Need to come up to speed on the changing cloud and container trends and technologies? If you feel out of the loop, this tech-transfer explainer should provide enlightenment.

    Once upon a time, virtual machines changed how we thought about servers. Then, the cloud changed how we thought about IT. Now, containers have started a new transformation. The latest entry is “serverless”—though I should point out immediately that the term serverless is a misnomer. Future cloud-native applications will consist of both microservices and functions, often wrapped as Linux containers.

    VMs and the cloud enabled DevOps, the practice of developers and IT operations staff collaborating to optimize technology processes. Cloud technologies’ dynamic compute and storage resources made it easier to provision resources. The idea behind DevOps is that developers no longer need to worry about infrastructure because that's taken care of in the background by programs such as Ansible, Chef, and Puppet.

    Then along came containers. Containers use far fewer resources than VMs by using shared operating systems. Containers are also easier to spin up and down when circumstances require it.

  • Scaling AMQ 7 Brokers with AMQ Interconnect

    Red Hat JBoss AMQ Interconnect provides flexible routing of messages between AMQP-enabled endpoints, including clients, brokers, and standalone services. With a single connection to a network of AMQ Interconnect routers, a client can exchange messages with any other endpoint connected to the network.

    AMQ Interconnect can create various topologies to manage a high volume of traffic or define an elastic network in front of AMQ 7 brokers. This article shows a sample AMQ Interconnect topology for scaling AMQ 7 brokers easily.

    AMQ Interconnect does not use master-slave clusters for high availability. It is typically deployed in topologies of multiple routers with redundant network paths, which it uses to provide reliable connectivity. AMQ Interconnect can distribute messaging workloads across the network and achieve new levels of scale with very low latency.

    The router accepts AMQP protocol–based connections from clients and creates AMQP connections to brokers or AMQP services. The router classifies incoming AMQP messages and routes the messages between message producers and message consumers.

    A messaging client can make a single AMQP connection into a messaging bus built with routers, and over that connection it can exchange messages with one or more message brokers connected to any router in the network. At the same time, the client can exchange messages directly with other endpoints without involving a broker at all.s

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.
