Let’s talk about Virtualization !

 

One car, one driver

Look at the traditional datacenter infrastructure where single application runs on a single server so if you need to run 100 applications then you will be required to implement 100 physical servers, now just think about the cost of hardware, maintenance, electricity or power consumption and day to day operations for all these applications running on single physical servers.

This is analogous to a single car, single driver, where the car helps get the person from "point A" to "point B" and the single driver represents the driver and sole passenger of the vehicle. If this were a single driver on a energy-efficient motorcycle or scooter, than would be reasonable, but people often drive alone much bigger vehicles,what Jeff would call "over-provisioning". Computer Chips have increased in processing power much faster than individual applications have increased their requirements, so as a result,you have over-provisioning.

Carpooling - one bus, one driver, and many other passengers riding along

What about sharing resources? We all know that now a days we have more powerfull computers/workstations/servers so running a single application on a powerfull server with great CPU & RAM that’s not fair because single application on such server won’t consume all these resources, so how you are going to fully utilize resources? The Virtualization ! yes, Virtualization help you out to share hardware resources among multiple applications, you create multiple virtual machines on single server.

Hope this will help you to understand the basic concept of #Virtualization.
