    Define virtualisation in layman terms

    We have to convince the governors that we'd like to go with virtualisation on our servers, but the last time we tried explaining to one governor her eyes glazed over.
    Are there any legitimate analogies we could use?
    Sort of like
    "imagine servers were tables, you have one table to hold a lot of files (a server role). you then have another table to hold another lot of files. virtualisation would be getting a much larger, sturdier table that could hold multiple files."

    i know its not great, but we need something that the governors can understand without delving into technical terms really.
    any help would be appreciated!

    Imagine we take one big, powerful server. Then we tell it that it's actually lots of little servers which we can do whatever we want with, without having to actually buy a new server each time.

    Any good?

    I've got my business manager believing there are 5 computers under his desk, only 4 of them are invisable. He's got to be careful were he put's his feet

    Still that's better than the conversation on our internet connection that involved tin cans and bits of string...


    Virtualisation: You buy 1 computer with a superiority complex, it becomes schitzophrenic.

    One I used a while ago was the people in a room scenario:

    One real server is like a room with its standard OS being a person, one person in a room has to do all the work and takes a certain amount of time to do so. If it is a big room/server then you can put more people in it so they can all work together to get the stuff done quicker.

    Assuming you have more work to do and no space for more people you can add another building/server and put more people in there to do yet more work. This also adds redundancy, if the power goes out to the server/building the other server/building can keep working.

    If you have a lot of stuff to work on files/boxes you can get a warehouse (centralised storage - SAN, NAS) where the stuff to be worked on can be stored and transported to/from.

    You can also get into trucks between the facilities being the network, bigger trucks etc. but its best to try and keep it only as complex as it needs to be.

    It is a way of caving up physical recourse to user computing, cooling and electrical power better.

    Best thing I did was to demonstrate it. Took my laptop to SMT and fired up a few different VMs to show how you could run multiple virtual computer on one physical computer.

    thanks for the ideas. we dont actually know what level they are expecting this to be pitched at, but all the ideas give us some options.
    thanks

    the problem is for those who dont really understand IT that is just you sat there running different programs on a PC. if they dont understand stuff in more depth then just showing them is like a mechanic showing you under the bonnet if you haven't got a clue about cars

    Okay, I've got it! You need a prop for this.

    Get 1x Russian doll (you know, the ones with more dolls in side).
    Keep the biggest doll hidden away to one side.
    Spread all the other dolls out in front of the audience.
    Point at the dolls and say "these are our servers".

    Now get the biggest dolls and say "If we buy 1 really big server, we can put all these other small servers inside the big"
    Demonstrate by putting the dolls away inside the big doll.

    "Thats Virtualisation - It'll save us money - Thank you" then bow

    "Server within a Server"
    Analogy: Hotel or Flats.. One Big building, with lots of little houses inside

    Or in a language they may understand: for £xx,xxx we can buy this really powerful server and on that we can put lots of other servers without having to spend more money..

    If its anything like our governor, go down the money route,

    10 servers = Lots of money
    1 server = 1/10th Lots of money

    They'll be buying in to the idea in no time!!

    it's not just the money aspect, they want to try and understand the reasoning and how it works.
