  • Cloud Native Applications in AWS supporting Hybrid Cloud – Part 1

    Let us talk first about what is cloud native and the benefits of SUSE Cloud Application Platform and AWS when building cloud native applications.

  • Cloud Native Applications in AWS supporting Hybrid Cloud – Part 2

    In my previous post , I wrote about using SUSE Cloud Application Platform on AWS for cloud native application delivery. In this follow-up, I’ll discuss two ways to get SUSE Cloud Application Platform installed on AWS and configure the service broker:

  • 10 Top Data Virtualization Tools

    With the continuing expansion of data mining by enterprises, it's no longer possible or advisable for an organization to keep all data in a single location or silo. Yet having disparate data analytics stores of both structured and unstructured data, as well as Big Data, can be complex and seemingly chaotic.

    Data virtualization is one increasingly common approach for dealing with the challenge of ever-expanding data. Data virtualization integrates data from disparate big data software and data warehouses - among other sources – without copying or moving the data. Most helpful, it provides users with a single virtual layer that spans multiple applications, formats, and physical locations, making data more useful and easier to manage.

  • Running MongoDB with OCS3 and using different types of AWS storage options (part 3)

    In the previous post I explained how to performance test MongoDB pods on Red Hat OpenShift with OpenShift Container Storage 3 volumes as the persistent storage layer and Yahoo! Cloud System Benchmark (YCSB) as the workload generator.

    The cluster I’ve used in the prior posts was based on the AWS EC2 m5 instance series and using EBS storage of type gp2. In this blog I will compare these results with a similar cluster that is based on the AWS EC2 i3 instance family that is using local attached storage (sometimes referred as "instance storage" or "local instance store").

  • OpenShift 4.1 Bare Metal Install Quickstart

    In this blog we will go over how to get you up and running with a Red Hat OpenShift 4.1 Bare Metal install on pre-existing infrastructure. Although this quickstart focuses on the bare metal installer, this can also be seen as a “manual” way to install OpenShift 4.1. Moreover, this is also applicable to installing to any platform which doesn’t have the ability to provide ignition pre-boot. For more information about using this generic approach to install on untested platforms, please see this knowledge base article.

Ubuntu 21.04 (Hirsute Hippo) Reached End of Life, Upgrade to Ubuntu 21.10 Now

Dubbed by Canonical as the “Hirsute Hippo,” Ubuntu 21.04 was released nine months ago, on April 22nd, 2021. It was the first Ubuntu release to use the next-generation Wayland display server by default for its Ubuntu Desktop flavor, which uses a modified version of the GNOME desktop environment. Ubuntu 21.04 didn’t make the plunge into the GNOME 40 desktop environment series due to its redesigned Activities Overview, but it did ship with support for GNOME 40 apps while being built on top of the older GNOME 3.38 desktop environment series.

  • Supplino is a variable benchtop power supply that you can build yourself | Arduino Blog

    Working with electronics requires access to stable power in a variety of voltages. Some components require 3.3V and others require 5V. Still others need 9V or 12V — there are many possibilities. You could keep a variety of wall warts on hand, but a variable benchtop power supply is a more convenient option. Supplino is one choice and this guide from Giovanni Bernardo and Paolo Loberto will walk you through how to build one. Supplino can accept anything from 4 to 40 volts and can output anything from 1.25 to 36 volts, with a maximum of 5A. An XH-M401 module with an XL4016E1 DC-DC buck converter handles the voltage regulation. Technically, you could use that alone to power your components. But the addition of an Arduino Nano board (or Nano Every) makes the experience far friendlier. It monitors the power supply output and drives a 1.8″ 128×160 TFT LCD screen, which displays the present voltage, amperage, and wattage.

  • Relocating Fedora's RPM database [LWN.net]

    The deadlines for various kinds of Fedora 36 change proposals have mostly passed at this point, which led to something of a flurry of postings to the distribution's devel mailing list over the last month. One of those, for a seemingly fairly innocuous relocation of the RPM database from /var to /usr, came in right at the buzzer for system-wide changes on December 29. There were, of course, other things going on around that time, holidays, vacations, and so forth, so the discussion was relatively muted until recently. Proponents have a number of reasons why they would like to see the move, but there is resistance, as well, that is due, at least in part, to the longstanding "tradition" of the location for the database.

Server: MongoDB vs. DynamoDB, Mirantis, and More

  • MongoDB vs. DynamoDB: What you need to know

    NoSQL databases have become more popular because of the need for more flexible backend solutions. These databases run applications that require a more flexible data structure than traditional structured databases can provide. Robust feature-rich NoSQL database platforms famous for NoSQL databases include MongoDB and DynamoDB. This article guide will compare these two databases to help you choose the right one for your project.

  • Mirantis brings secure registries to Kubernetes distros | ZDNet

    Mirantis Secure Registry, formerly Docker Trusted Registry, provides an enterprise-grade container registry solution. You can use this as a foundation to build a secure software supply chain. It does this by providing you with access to a container image registry that has enhanced levels of security beyond that of public registries. This, in turn, gives you more control over this critical part of their software supply chain. The comprehensive, built-in security enables users to verify and trust the automated operations and integration with Continuous Integration/Continuous Delivery (CI/CD) pipelines to speed up application testing and delivery. You can use MSR alongside your other apps in any standard Kubernetes 1.20 and above distribution, via standard Helm techniques. While the new MSR is no longer integrated with Mirantis Kubernetes Engine (MKE) as it was earlier, it still runs as well as ever on MKE as it does with any other supported Kubernetes distribution.

  • The Success of ‘Open-hearted’ Partnerships in the Cloud | SUSE Communities

    The future is open — and it’s better together. At SUSE, we pride ourselves on our partnerships, and sometimes what we can achieve together surpasses even our greatest hopes. That’s what our award-winning, cloud-based, high-performance computing (HPC) partnership with UberCloud, Dassault Systèmes, and Google Cloud achieved, by enabling 3DT Holdings researchers to create an affordable, real-time heart surgery simulator for physicians to use when it matters most. This is an ongoing relationship with the Living Heart Project that we think is just the beginning of what this ground-breaking research can achieve — and the lives it can save.

Programming Leftovers

  • An outdated Python for openSUSE Leap [LWN.net]

    Enterprise distributions are famous for maintaining the same versions of software throughout their, normally five-year-plus, support windows. But many of the projects those distributions are based on have far shorter support periods; part of what the enterprise distributions sell is patching over those mismatches. But openSUSE Leap is not exactly an enterprise distribution, so some users are chafing under the restrictions that come from Leap being based on SUSE Enterprise Linux (SLE). In particular, shipping Python 3.6, which reached its end of life at the end of 2021, is seen as problematic for the upcoming Leap 15.4 release. [...] OpenSUSE and SLE have generally been aligned over the years. In 2020, Leap and SLE grew even closer together. The build system and repositories between the two were shared starting with Leap 15.2, which corresponded to the second "service pack" (SP) of SLE (i.e. SLE 15-SP2). In 2021, with Leap 15.3 and SLE 15-SP3, the two distributions effectively merged, such that all of the base packages were shared between the two. To a first approximation, Leap is an openSUSE-branded version of SLE, much like what CentOS used to be for Red Hat Enterprise Linux.

  • Make Your Python CLI Tools Pop With Rich | Hackaday

    It seems as though more and more of the simple command-line tools and small scripts that used to be bash or small c programs are slowly turning into python programs. Of course, we will just have to wait and see if this ultimately turns out to be a good idea. But in the meantime, next time you’re revamping or writing a new tool, why not spice it up with Rich?
