      The simple answer is because of consolidation, footprint, energy, cooling, cost savings, administration simplification.

      The long answer is paging @scottalanmiller.

      okay.. How does it work?

      How does virtualization work? Just like running a program on Windows 10, each VM is a separate program that runs on the hypervisor.

      and in a regular set up you'd use this to run servers? controllers? back ups? Images?

      Those are weird things to list together.

      A VM is nothing more than a server running in a container instead of directly on the hardware it's running on.

      i.e. You have a physical server - you install a hypervisor (the thing that allows you to have VMs running under it)... then you create VMs under the hypervisor. Each VM acts like it's own piece of physical hardware - in general, the Operating System running in the VM has no idea that it's not running on physical hardware (OK before someone blasts me, most OSes today do know they are running in a VM, but that's beside the point)... now treat each VM as if it was running on it's own hardware.

        one of the major benefits you get is hardware abstraction - this means you can move the VM to almost any other hardware and it doesn't know any difference. In the case of a disaster, you build a new server with the hypervisor, restore the VM from backups and just go.

          Is there a certification course?

          It is very important to have a basic understanding virtualization because damn near everything is virtualized these days. Once you have a basic understanding, you would be better off learning Cloud technologies. It is virtualization on steriods.

              You have to be careful with the container term as a VM and a container are technically different, but using container is a good term to help get the point across.

                yeah - I know... containers came on the scene.. now we have to be extra careful in how we explain things...

                                Go to the Youtube vids or Udemy course if you want focused material on it. Then the sidebar conversations will make more sense.

                                  The simple answer to "why virtualize" is that if you don't, everyone here will make fun of you (ask me how I know).

                                    It is difficult to have a valid reason to run a physical server anymore.

                                      There's always a snowflake reason, but you should always virtualize unless you have super specific reasons not to.

I later found out that like 10+ years ago they got SCREWED by a poorly implemented VM Ware setup for production systems. Cost them some customers and a bunch of money, so it kinda made sense. I've been working really hard to break them out of their late 90s mindset.

                                          Yeah, that's not your fault and totally out of your hands. It's extremely hard to change the mind of older generations no matter how right you are and no matter how grossly wrong they are. There's usually a lot of emotion in their reasoning as well.

                                            @Obsolesce exactly, plus the IT guy before me sucked, so I had a while before they really listened to my advice. We are about to roll out a physical SQL server, but I'm trying to get them to put hyper-v 1st and then just the 1 VM with all available resources to test the performance.
