What is cloud computing?

TechnologyLesson on requestFree to read

Quick answer

Cloud computing is using computing resources — servers, storage, software — over the internet instead of on your own machine. You rent capacity on demand from providers and access it anywhere, paying for what you use. Data and programs run on remote data centers, not your local device.

  1. Data and programs run on remote data centers, not your local device.
  2. You scale up or down instantly, paying only for what you use.
  3. Common models deliver storage, platforms, and software over the internet.
  4. It powers most modern websites, apps, and AI services.
