Let’s say you a computer is a like a whiteboard.
You need a 2x3m white board. You can just get one of that size. That would be like getting a physical computer that you need.
With virtualization, instead of getting a 2×3 whiteboard, you (your company, or a hosting company) get a 100×100 whiteboard, and you can rent a 2×3 chunk of it. Now if you realize that 2×3 isn’t big enough for you, you can easily move up to say 4×3. If you needed another chunk you can just rent another chunk of it. It’s very quick to do, compared to going to the store and buying a separate one. Then if you don’t need it anymore you can just stop using it.
What happens if the 100×100 board runs out of space? Well they hosting company will have multiple and they can rent you out a space on a different board. It’s all the same to you because it’s just space.
