Serverless doesn't mean there are no servers; it just means the cloud provider takes care of them so you don't have to.

Invisible Server Management

This is a way to run small pieces of software independently only when they are needed, rather than keeping a whole app running constantly.

Running Code as Functions

Instead of building everything from scratch, you use pre-made tools for things like user logins or sending notifications.

You are only charged for the exact time your code is running, which is like paying for electricity only when the light is on.

The system automatically adds more power if many people use your app at once and scales back down when they leave.

Your code acts like a reaction to a specific action, such as a user clicking a button or uploading a photo.

Each time your code runs, it starts from scratch without remembering what happened before, which helps keep things simple and fast.

If your code hasn't been used in a while, it might take a few extra seconds to 'wake up' and start running again.

This is a special helper that takes incoming requests from the internet and sends them to the right piece of code.

The service provider automatically handles all the boring maintenance, like fixing security holes and updating the underlying systems.

These are databases that automatically store your information and adjust their size based on how much data you have.

Instead of one giant program, you build your app out of many small, specialized parts that talk to each other.
