Scalability

Alright kiddo, so imagine you have a toy box with all your favorite toys in it. You can easily play with all of them because they fit in the box, but what if you get a new toy and you want to play with it too? You can't just shove it in the box, right? You might need a bigger box to fit them all so you can play with them together.

Well, that's kind of what scalability means. When grownups talk about scalability, they are talking about how easy or hard it is to make something bigger. So, when a company, like Amazon, creates a website to sell stuff and more and more people start buying from that website, it's important that the website can handle all those people without breaking. If Amazon's website crashes because too many people are trying to use it at once, that's a bad thing for Amazon, and customers will get upset because they can't buy what they want.

So, Amazon needs to make their website scalable by increasing its capacity to handle more people using it without breaking. Just like you need a bigger box or a toy chest to store more toys, Amazon needs to upgrade its website so it can handle more customers using it.

Does that make sense, kiddo?
