I admit it, some tools confuse me. I know they must be amazing, because
programs don't get popular by being dumb (well, reality TV, but that's
another story). I have the same sort of confusion with Vagrant that I

its simplest form.
Because you're a reader of Linux Journal, you probably
already know that Linux has a rich virtualization
ecosystem. KVM is the de facto standard, and VirtualBox is widely used for desktop
virtualization. Veterans should remember Xen (it's still in a good shape,
by the way), and there is also VMware (which isn't free but runs on Linux
as well). more>>
It's time for another Readers' Choice issue of Linux
Journal! The format
last year was well received, so we've followed suit making your voices
heard loud again. I couldn't help but add some commentary in a few places,
but for the most part, we just reported results. Please enjoy this year's

We're all familiar with the idea of virtualized computers. Not only
are they a great way to better utilize resources in a server room,
but they also allow you to create and destroy servers in the blink of an
eye. That's perfect for a lab or training environment. Unfortunately,
it's always taken a rack of actual hardware to create a training lab
for Cisco hardware. more>>
Linux-based container infrastructure is an emerging cloud technology
based on fast and lightweight process virtualization. It provides
its users an environment as close as possible to a standard Linux
Take on "dependency hell" with Docker containers, the lightweight and nimble cousin
of VMs. Learn how Docker makes applications portable and isolated by packaging them
in containers based on LXC technology.
With Red Hat Enterprise Virtualization, data centers may take advantage of updated hardware without the expense of porting older applications to a new OS. See more in the following video from Red Hat, and then read the free white paper to go in-depth. more>>

Linux enthusiasts might think the idea of running a Linux virtual machine
on Microsoft's Azure service is like finding a penguin sun tanning in
the Sahara. Linux in the heart of the Microsoft cloud? Isn't that just
wrong on so many levels?
Virtualization is now a staple of the modern enterprise. As more and more
shops switch to the virtual paradigm, managing those new virtual
resources is a critical part of any deployment. For admins using
Microsoft- or VMware-based hypervisors, powerful management tools
are available to keep their virtual houses in order. more>>
