Before we get started with our list of virtual machine software products for you to review, I’d like to recommend reading my new guide to the best virtual software training. This guide covers salary ranges, job skills, and online training options for beginners to learn how to set up, configure, and support virtual servers and desktops. There is even a free training for VirtualBox.
A VPS runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software-defined, are able to be much more easily created and configured. They are priced much lower than an equivalent physical server. However, as they share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines.[1]
