# What is Cloud Computing?

It is the provision of computing services via remote servers over the internet.

## Overview
It allows you to perform transactions not on your own computer, but on powerful servers at the other end of the internet. In this way, you can process large data or run applications even if your hardware capacity is low. It is a kind of digital rental warehouse and processing power service.

*Analogy: It's like getting electricity from the grid instead of having a generator in your own home; You use what you need and pay for what you use.*

## How it works
You upload your applications or data to remote servers accessible over the internet. The service provider manages this infrastructure, and you focus only on your software or data.

## Where it is used
It is used when hosting websites, big data analysis and backup systems.

## Commonly confused with
It may be confused with internet storage, but it is not just storage but also processing power service.
