What Is Deployment

Simple Explanation

Deployment is like moving your app from your bedroom to a store so everyone can access it.

What Happens When You Deploy

• Your code goes from your computer to a server on the internet

• People can access your app by visiting a URL

• Your app runs 24/7 without your computer being on

Why You Need to Deploy

If you want anyone else to use your app, it needs to be online.
