  • VMware vSphere vs Proxmox: Which is best for your business?

    Choosing a virtualisation tool can be tricky, so we've put two of the most popular side by side
    Customers are faced with a host of considerations when it comes to trying to decide on what virtualisation and containerisation software to use, and the differences between vendors are not always clear.

    In order to better inform buyers, we've decided to take a look at two of the best-known software packages out there, Proxmox and VMware vSphere, and break down what it is they do and how they may benefit your business.

  • KubeVirt Joins Cloud Native Computing Foundation

    This month the Cloud Native Computing Foundation (CNCF) formally adopted KubeVirt into the CNCF Sandbox. KubeVirt allows you to provision, manage and run virtual machines from and within Kubernetes. In joining the CNCF Sandbox, KubeVirt now has a more substantial platform to grow as well as educate the CNCF community on the use cases for placing virtual machines within Kubernetes. The CNCF onboards projects into the CNCF Sandbox when they warrant experimentation on neutral ground to promote and foster collaborative development.

    For our part, Red Hat has been a contributor and advocate for KubeVirt and we’ve been leveraging it to play with some technologies you may remember. At Red Hat Summit you watched us demonstrate the capabilities of a Kubernetes Native platform bringing together the capabilities of VMs, containers, networking and storage. If you’re an OpenShift customer you may have started to play with Container-native virtualization (CNV), available via tech preview — this uses KubeVirt under the hood.

  • Software Development, Microservices & Container Management – Part II – Why Containers and Cloud Native Application Platform?

    Lots of the developers, Solution Architects and Business Owners have doubts for Virtualization versus Containers and Cloud Native Application Platform; lots of questions are being discussed based on such doubts; Are containers and PaaS replacing Virtual Machines?

Raptor Computing Is Working On More AMD Radeon Driver Improvements For POWER

Similar to 64-bit ARM (AArch64) improvements we've seen with time for the Radeon Linux driver, Raptor's Timothy Pearson has been working to improve the Radeon support for PowerPC or more specifically POWER9. While NVIDIA offers a POWER9 graphics driver for IBM POWER servers, AMD Radeon graphics jive much better with Raptor's target customers thanks to the open-source driver stack -- allowing a fully open-source graphics/compute stack with the AMD hardware sans the closed-source microcode required by the GPUs, but much better than the completely closed-up NVIDIA driver stack.

Using Menus For Command Line Programs and Scripts

THE holidays are coming (Christmas approaching), so I've taken advantage of some spare time to menu-ise commands that I use frequently. Those commands aren't the mere opening of an application and they often require dealing with input and output (in the command line). So I've created menu.sh and used dialog to craft the following menu, e.g. for operations associated with Techrights. I invoke this menu with the click of one button (of the mouse).

Rianne has a similar menu for commands she often runs (which are long and would otherwise need pasting or typing in length). Her menu looks something like this:

Rianne's menu

Here's the code (bash file) that renders the menu above (it's really that simple!):

#!/bin/bash

HEIGHT=15
WIDTH=40
CHOICE_HEIGHT=4
BACKTITLE="Aloha, Rianne"
TITLE="Rianne @ Ted"
MENU="Choose one of the following options:"

OPTIONS=(1 "Start VPN"
         2 "REDACTED"
         3 "REDACTED"
	4 "REDACTED"
	5 "REDACTED"
	6 "REDACTED"
	7 "REDACTED"
)

CHOICE=$(dialog --clear \
                --backtitle "$BACKTITLE" \
                --title "$TITLE" \
                --menu "$MENU" \
                $HEIGHT $WIDTH $CHOICE_HEIGHT \
                "${OPTIONS[@]}" \
                2>&1 >/dev/tty)

clear
case $CHOICE in
        1)
            echo "You chose Option 1"
sh ~/vpn.sh ;;

        2)
            echo "You chose Option 2"
REDACTED COMMAND ;;
        3)
            echo "You chose Option 3"
REDACTED COMMAND ;;
        4)
            echo "You chose Option 4"
REDACTED COMMAND ;;
        5)
            echo "You chose Option 5"
REDACTED COMMAND ;;
        6)
            echo "You chose Option 6"
REDACTED COMMAND ;;
        7)
            echo "You chose Option 7"
REDACTED COMMAND ;;

Hopefully this inspires other people out there to do the same. It takes a while to set up, but it's a big time saver over the long run.
