  • World Backup Day: A plan of action

    World Backup Day reminds us all of just how important backups are. You don't get how important they are, perhaps, until you've experienced an outage that you can't recover from by any troubleshooting method. Backups are a pain but they are a necessary evil and can save you when things go bad. And things always go bad. This article helps you make a plan.

  • Running an event-driven health management business process through a few scenarios: Part 1

    In the previous series of articles, Designing an event-driven business process at scale: A health management example (which you need to read to fully understand this one), you designed and implemented an event-driven scalable business process for the population health management use case. Now, you will run this process through a few scenarios.

  • Getting to open hybrid cloud

    So, you’ve read our e-book and are convinced that adopting an open hybrid cloud Platform is a key part of digitally transforming. Great! Now how do you get your applications and associated infrastructure there?

    There are many aspects that should be considered when digitally transforming and adopting an open hybrid cloud including people, culture, process, and technology. While these are all important, in this post we will focus on process and technology.

    A common way of speaking about migrating or modernizing workloads to the cloud was popularized in 2016 by Amazon Web Services in their post, "6 Strategies for Migration Applications to the Cloud." We will use the categorization popularized in that article to explore how Red Hat is making it quicker and easier to move your applications and their associated infrastructure to the open hybrid cloud.

  • Command and control: The Red Hat Ceph Storage 4 Dashboard changes the game

    Ease of use was a key development theme for Red Hat Ceph Storage 4. In our last post, we covered the role that the new install UI plays in enabling administrators to deploy Ceph Storage 4 in a simple and guided manner, without prior Ceph expertise.

    Simplifying installation is only the first step—the second step is simplifying day-to-day management. To meet this challenge, Ceph Storage 4 introduces a new graphical user interface called the Dashboard.

  • Three ways our hybrid cloud architecture makes it easy to add AI to fulfillment
  • Gain transparency into fulfillment decisions

    In a previous blog, I introduced IBM Sterling Fulfillment Optimizer With Watson® and provided answers to five frequently asked questions. Once clients have implemented this AI-powered solution to optimize fulfillment, they tend to have another question: Why did Sterling Fulfillment Optimizer make the decisions that it did? In this blog, we’ll look at what’s in Watson’s head.

    When an order is sent to Sterling Fulfillment Optimizer, the order goes through many rules, configurations, constraints, and cost-optimization comparisons to determine the best fulfillment option. Sometimes, as a user, the recommendation intuitively feels right, but other times it may not – particularly if you’re dealing with complex orders and a complex fulfillment network. If an order is placed in Chicago and Sterling Fulfillment Optimizer recommends that different order lines for the order be fulfilled from nodes in Los Angeles and Dallas, you may have difficulty understanding why that was the best choice to maximize profits.

    What isn’t immediately evident is that behind the scenes, Sterling Fulfillment Optimizer is using big data analytics, AI, and machine learning to look for trends and patterns. It analyzes sell-through patterns, rate-of-sale and probability-of-sale data to determine the risk of stockouts or markdowns for each SKU node combination, automatically calculating the lowest overall fulfillment cost at that moment. This is critical because that moment in time is always changing as the fulfillment network and sell-through patterns continuously change, and business preferences may change as well. Remember from the last blog that I discussed how you may decide to prioritize one or more factors over the total cost due to promotions or seasonality. In this example, where the order is fulfilled from Los Angeles and Dallas, the solution determined — based on visibility into real-time data and balancing multiple factors simultaneously — that if the order had been fulfilled from a single node in Chicago, which at that moment was low on inventory, the risk of stockout would have been high.

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.
