A taxi instead of owning a car
Day 28 of 149
👉 Full deep-dive with code examples
The Car Analogy
Owning a Car (Traditional Server):
- Pay for the car even when parked
- Pay for gas even when not driving
- Maintenance, insurance, parking...
- Costs money 24/7!
Taking Taxis (Serverless):
- Pay when you ride
- No car sitting idle
- No maintenance worries
- Pay per trip!
How It Works
Traditional: Server runs 24/7, you pay 24/7
Serverless: Code runs on demand (when triggered)
User makes request →
Your code wakes up →
Runs →
Goes back to sleep
You usually pay based on execution time and usage.
Famous Examples
- AWS Lambda
- Vercel Functions
- Cloudflare Workers
When to Use
✅ Good for: Unpredictable traffic, APIs, webhooks
❌ Not great for: Long-running processes, real-time apps
In One Sentence
Serverless lets your code run on demand, charging you based on what you use.
