What is AWS, What is Cloud Computing? AWS SCOPE & CAREER

 

What is Cloud Computing?

Cloud Computing means using servers, storage, databases, networking, software, analytics, and intelligence over the internet instead of managing physical hardware.

👉 Example:

• Gmail → No mail server at home

• Netflix → No DVD or local storage

• Google Drive → No pen drive needed

In simple words:

“Pay only for what you use, when you use it, without owning hardware.”
