Serverless vs Traditional: The Architecture of Infinite Scale

## The End of the Idle Server
In traditional hosting, you rent a server 24/7. If no one visits at 3 AM, you still pay. If 1 million visit at noon, the site crashes.

### The Serverless Revolution (Functions as a Service)
- **Zero to Infinite Scale**: Code only 'wakes up' when there is a request.
- **Pay per Use**: You pay per millisecond of computing, not per server hour.
- **Global Resilience**: Code runs at the Edge, close to the user, not in a single data center.

### Why RET Uses Serverless?
We use Next. js and Vercel/AWS Lambda to ensure that:
1. Your site loads fast in Tokyo or San Francisco.
2. Your e-commerce withstands Black Friday without crashing.
3. You don't pay for infrastructure you don't use.

**Performance isn't luck. It's architecture.**
