🌐 Web Service Basics

To deploy a web app, you first need a server to run your code

Now that you have a server, you need a database to store user data

When repeated queries flood the DB, it slows down. Cache frequently accessed data in memory for faster responses

As users grow, a single server can't handle the load. Distribute traffic across multiple EC2 instances

Connect an easy-to-remember domain name to your service

Add a CDN to deliver content quickly to users worldwide
