Owning it vs. renting it
Think of it like electricity. You don't own a power plant at home — you just plug in and pay for what you use. Cloud computing works the same way, but for computers.
Your own machine
You buy the hardware, install everything yourself, and fix it when it breaks. If it's too small later, you buy a bigger one.
A rented computer, online
Someone else owns and maintains the hardware, far away in a data center. You just log in and use exactly what you need.
How much do you want to rent?
Cloud services come in different "sizes" — think of it like renting a kitchen to cook a meal.
Rent the raw building blocks
Bare servers, storage and networking. You set everything up yourself. Good for teams who want full control.
Rent a ready-to-cook kitchen
The tools and appliances are already installed. You just bring your recipe — your code — and start building.
Order the finished meal
A complete app, ready to use in your browser. No setup at all — think email, video calls, or document editors.
Where does "the cloud" actually live?
It's not really in the sky — it's rows of real computers, called servers, sitting in huge buildings called data centers.
Your device
Phone, laptop, or tablet
The internet
Carries your request in milliseconds
A data center
Real servers, often on another continent
Cloud computing in everyday life
If you've done any of these, you've already used the cloud.
Streaming a show
Video is stored and played from a remote server
Checking email online
Your inbox lives on someone else's computer
Saving photos to a backup app
Files are copied to a data center, not just your phone
Joining a video call
The call is routed and mixed through cloud servers
The one-sentence summary
Cloud computing means using computing power, storage, or software that lives on someone else's servers — accessed over the internet, paid for as you go, and ready whenever you are.
