Network function virtualization

Okay kiddo, so imagine you have a big box of toys. Each toy has a unique function and is really good at doing that one thing. Now, let's say you want to play a game that requires you to build something specific with your toys, but you don't have the exact toy you need.

Network Function Virtualization (NFV) is like playing with your box of toys, but in a computer. Instead of having to physically find the toy you need, like a firewall or a router, NFV lets you create a virtual version of that toy in the computer.

This means that instead of having a bunch of big boxes with specific toys, you can create these toys virtually whenever you need them. This makes things easier and more efficient because you can use the same computer to make different toys for different games.

So, when someone talks about NFV, they're really talking about using computers to create virtual versions of specific networking tools that you might need to use. This makes things quicker, more flexible, and more cost-effective because you don't need to go and buy a new box of toys every time you want to play a new game.
