How does the cloud work?
Quick answer
The cloud works by letting you store data and run programs on powerful remote computers over the internet, instead of on your own device. Companies run huge data centers, and you rent a slice of their computing power and storage on demand.
Step by step
- Your data and apps live on remote servers in data centers.
- You access them over the internet from any device.
- Providers maintain the hardware; you rent what you need.
- It scales up or down instantly with demand.
- Examples: cloud storage, streaming, and web apps.
