Notes: Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here.

  • Snap Vs Flatpak Vs Appimage: Know the Differences | Which Is Better
    Published on Tux Machines (http://www.tuxmachines.org) Home > content > Snap vs Flatpak vs AppImage: Know The Differences | Which is Better Snap vs Flatpak vs AppImage: Know The Differences | Which is Better By Rianne Schestowitz Created 08/12/2020 - 8:29pm Submitted by Rianne Schestowitz on Tuesday 8th of December 2020 08:29:48 PM Filed under Software [1] Every Linux distribution has its own package manager tool or command-line based repository system to update, install, remove, and manage packages on the system. Despite having a native package manager, sometimes you may need to use a third-party package manager on your Linux system to get the latest version of a package to avoid repository errors and server errors. In the entire post, we have seen the comparison between Snap, AppImage, and Flatpak. Snap, Flatpak, and AppImage; all have their pros and cons. In my opinion, I will always prefer the Flatpak package manager in the first place. If I can?t find any packages on Flatpak, then I?ll go for the AppImage. And finally, Snap is an excellent store of applications, but it still requires some development. I would go to the Snap store for proprietary or semi-proprietary applications than main applications. Please share it with your friends and the Linux community if you find this post useful and informative. Let us know which package manager do you prefer to use on your Linux system. You can write also write down your opinions regarding this post in the comment section.

  • Ubuntu Server Guide Basic Installation Preparing to Install
    Ubuntu Server Guide Welcome to the Ubuntu Server Guide! This site includes information on using Ubuntu Server for the latest LTS release, Ubuntu 20.04 LTS (Focal Fossa). For an offline version as well as versions for previous releases see below. Improving the Documentation If you find any errors or have suggestions for improvements to pages, please use the link at thebottomof each topic titled: “Help improve this document in the forum.” This link will take you to the Server Discourse forum for the specific page you are viewing. There you can share your comments or let us know aboutbugs with any page. PDFs and Previous Releases Below are links to the previous Ubuntu Server release server guides as well as an offline copy of the current version of this site: Ubuntu 20.04 LTS (Focal Fossa): PDF Ubuntu 18.04 LTS (Bionic Beaver): Web and PDF Ubuntu 16.04 LTS (Xenial Xerus): Web and PDF Support There are a couple of different ways that the Ubuntu Server edition is supported: commercial support and community support. The main commercial support (and development funding) is available from Canonical, Ltd. They supply reasonably- priced support contracts on a per desktop or per-server basis. For more information see the Ubuntu Advantage page. Community support is also provided by dedicated individuals and companies that wish to make Ubuntu the best distribution possible. Support is provided through multiple mailing lists, IRC channels, forums, blogs, wikis, etc. The large amount of information available can be overwhelming, but a good search engine query can usually provide an answer to your questions.

  • Install a Microk8s Single Node Cluster Locally on Windows 10
    Install a MicroK8s single node cluster locally on Windows 10 By Philippe Beraud, Microsoft France This walkthrough guides you through all the steps required to create and configure a MicroK8s cluster on Windows 10. Kubernetes1 runs on Linux. As such, MicroK8s2 provides a single command installation of the latest Kubernetes release on a Linux machine for development and testing. MicroK8s is easy to install and use on Ubuntu or any other Linux distro which supports snaps, i.e. pre-packaged applications (similar to Docker containers). Although Windows 10 now has some very useful features, such as the ability to install Ubuntu as an app, the integration of Windows Subsystem for Linux 2 (WSL2) doesn’t provide (yet) all the Ubuntu functionalities required to make MicroK8s run smoothly right out-of-the-box (OOB) and thus use the snap daemon. If you wish to experiment with running MicroK8s semi-natively, see: • Discourse post Using snapd in WSL2 • Post Running Snaps on WSL2 (Insiders only for now) along with the short YouTube video Use this ONE trick to run Linux Snap packages in Windows Subsystem for Linux 2 (WSL2) For now, and for the sake of simplicity for anyone looking to try out Kubernetes on Windows 10, let’s run MicroK8s on Windows 10 with virtualization. MicroK8s will install without problems on Ubuntu on a virtual machine (VM). The Canonical way to get a Linux VM on Windows 10 and to run MicroK8s in it is with multipass. Multipass gives you an easy to use interface to manage VMs on Windows 10 – Same is true on MacOS and Linux -.
