Today, when we open a website, use a mobile app, watch videos, or use online government services, we are using cloud computing, even without knowing it.
What is Cloud Computing?
Cloud computing means using servers and computers through the internet instead of using your own computer or office server.
In simple words:
Cloud = Internet-based computers that store data and run applications
---Simple Example
Old Method (Without Cloud)
- Files saved only on one computer
- If computer fails, data is lost
- Access only from one place
Cloud Method
- Files saved online
- Access from mobile, laptop, or office
- Data remains safe even if device is lost
Saving files in Google Drive instead of saving only on your laptop.
Why Is It Called Cloud?
In computer network diagrams, the internet is drawn as a cloud shape. That is why internet-based services are called cloud services.
Users do not need to know where the server is located. They only use the service.
