Cloud computing might sound like something floating in the sky, but in reality, it’s all about delivering computing services — like storage, software, and processing power — over the internet. Instead of buying and maintaining your own physical hardware, you can access what you need from remote servers hosted by cloud providers.
What is Cloud Computing?
Cloud computing means using the internet (“the cloud”) to access computing resources like storage, software, and processing power — instead of relying on your personal computer’s hardware.
Instead of buying expensive servers or keeping all your files locally, you can rent these services from a cloud provider and access them anytime, anywhere.

How Does Cloud Computing Work?
Imagine the cloud as a massive network of servers spread across the globe. These servers store data, run applications, and process tasks for millions of users at the same time.
When you upload a photo to Google Photos or stream a movie from Netflix:
-
Your device sends a request to the cloud server.
-
The server processes the request and sends the data back to you in real time.

Real-Life Examples of Cloud Computing
You use cloud computing every day, often without realizing it:
- Google Drive, Dropbox, OneDrive → Store and share files without USB drives.
- Netflix, YouTube, Spotify → Stream videos and music without downloading large files.
- Gmail, Outlook, Yahoo Mail → Access emails from any device, anywhere.
- Zoom, Microsoft Teams, Google Meet → Video calls powered by cloud servers.
Why Use Cloud Computing?
- No need for expensive hardware → Cloud providers handle servers and maintenance.
- Access anywhere → All you need is an internet connection.
- Scalable → Easily increase storage or computing power when needed.
- Secure & backed up → Providers often have advanced security and redundancy.
Final Thoughts
Cloud computing has transformed the way we store, access, and use data. Whether you’re sharing holiday photos with friends, running a business app, or watching your favorite show, you’re probably using the cloud right now.
