What is AWS? A Beginner's Guide to Amazon Web Services
In this beginner’s guide, we’ll break down Amazon Web Services (AWS) — what it is, what it offers, and why it’s such a big deal in the world of tech.
🧠 What is AWS?
Amazon Web Services (AWS) is a cloud computing platform offered by Amazon. It provides on-demand access to computing resources, such as servers, databases, storage, and more — all through the internet.
Instead of buying and managing physical servers, you can rent what you need from AWS, scale it as your app or business grows, and only pay for what you use.
🚀 Why Do People Use AWS?
Here’s why millions of businesses and developers choose AWS:
- Scalability – Start small and scale big without switching platforms.
- Cost-Effective – Pay-as-you-go pricing means no upfront infrastructure costs.
- Reliable – AWS runs in multiple data centers around the world, ensuring high availability.
- Secure – Trusted by companies like Netflix, NASA, and Airbnb.
- Huge Ecosystem – Over 200 fully featured services for compute, storage, AI, IoT, and more.
