What is Cloud Computing & AWS?

Definition: Cloud computing means renting computing resources — servers, storage, databases — over the internet instead of buying and running your own. Amazon Web Services (AWS) is the world's largest cloud provider, offering hundreds of these services on demand.

The simple analogy

Owning servers is like owning a power generator: expensive, and you maintain it yourself. The cloud is like plugging into the electricity grid — you use what you need and pay only for that. AWS is one of the biggest "grids" for computing.

What you can do with AWS

• Run websites and apps on virtual servers
• Store unlimited files and back up data
• Host databases without managing hardware
• Run AI, analytics, and big-data workloads
• Scale instantly from one user to millions

AWS launched in 2006 and now powers a huge share of the internet — Netflix, Airbnb, and countless startups run on it.

💡 Why learn AWS? Cloud skills are among the highest-paid, most in-demand skills in tech, and AWS is the market leader.
